A dynamic analysis of water footprint of Jinghe River basin

Water footprint in a region is defined as the volume of water needed for the production of goods and services consumed by the local people, Ecosystem services are a kind of important services, so ecological water use is one necessary component in water footprint. Water footprint is divided into green water footprint and blue water footprint but the former one is often ignored.In this paper waterJootprint includes blue water needed by agricultural irrigation, industrial and domestic water demand, and green water needed by crops, economic forests, livestock prochtcts, forestlalands and grasslands. The study calculates the footprint of the Jinghe River basin in 1990, 1995, 2000 and 2005 with quarto methods. Results of research show that water footprints reached 164.1 ×10^8m3, 175. 69 ×10^8m3 and 178. 45 ×10^8m3 respectively in 1990, 1995 and 2000 including that of ecological water use, but reached 77.68×10^8m3, 94.24×10^8m3, 92.92×10^8m3 and 111.36 ×10^8m3 respectively excluding that of ecological water use. Green water.footprint is much more than blue water footprint; thereby, green water plays an important role in economic development and ecological construction The dynamic change of water footprints shows that blue water use increases rapidly and that the ecological water use is occupied by economie and domestic water use. The change also shows that water use is transferred from primary industry to secondary industry In primary industry, it is transferred from crops farming to forestry, and animal agriculture. The factors impelling the change include development anticipation on econonomy; government policies, readjustment of the industrial structure, population growth, the raise of urbanization level, and structurul change of consumption, low level of waler-saving and poor ability of waste water treatment.With blue water use per unit, green water use per unit, blue water use structure and green water use structure, we analyzed the difference of the six ecologieal function districts of the Jinghe River     

Study on the Definition and Allocation of the Rights to Water Utilization in the Ecological Environment

With the rapid development of population and economy, the conflict between the supply and demand of water resources is becoming outstanding increasingly, In China, many people concern about the problems of ecological environment water expenditure.However, owning to the shortage of water resources and indefinite water rights, “the hustle effect” of per capita water resource is appeared, Moreover. it caused a series of environment problems. This article differentiates and analyzes the relevant concepts about the ecological enviromnent, and puts forward the defined concept of the rights to the ecological environment water utilization. In addition, it points out the characteristic of those rights, and does elementary study on the allocation principle, methods, and steps on the rights.     

Research on industrialization of eco-agriculture：theoretical framework and the case of Yunnan,Chinav

The industrialization of eco-agriculture has applied modern science technology in accordance with ecological principles and has promoted agricultural production.As a subsystem of agricultural industrial clusters,the industrialization of eco-agriculture is the specific applications of cluster concept in the industrialization of eco-agriculture development.Industrialization of eco-agriculture cluster will achieve eco-agriculture and interact with industrial cluster which forms eco-agriculture integration and composite industry and ultimately realize the new benign circulation eco-agriculture model.According to the ecological engineering basic principles of recycling of the overall coordination,industrialization of eco-agriculture is focusing on the main systems operating coordination between the various subsystems and its various factors,and will maintain a reasonable ecological and economic structure to ensure the recycling of natural resources.Industrialization of eco-agriculture in Yunnan has adjusted the agricultural production structure to keep the stability of the gross grain production and economic development and has taken effective measures to vigorously improve land use and land productivity.Various ways of improving soil fertility has vigorously promoted other water-saving agricultural technologies.Ecological protection of rice no-tillage,cultivation of crop cultivation of the integrated control crop disease pests grass and agricultural production have taken the sustainable development.     

Measuring economic loss caused by ecological damages： a case study of China＇s forest ecosystem in 2005

At present about 60% of ecosystem has been damaged and degraded severely, resulting in enormous ecological loss globally. The essential cause is the irrational utilization of ecosystem by humankind, so it is tire key to changing improper environmental performance of humankind so as to prevent ecosystem from being damaged The quantitative valuation on the loss of ecological damage is an effective tool to guide human eco-environmental performance. In this paper, the concepts related to the valuation on ecological damage cost are introduced,＂ uncertainties that might arise in the valuation on the loss of ecological damage such as area coverage of valuation, ecological damage quantity, borders of ecological damage cost and data support are analyzed and the valuation approaches for the loss of ecological damage are also discussed As a case study, the economic losses of ecological damage of forest in 2005 in China are valuated.     

Ecological footprint analysis on the traditional rice-fish agricultural area： a case study of Qingtian County, Zhejiang Province, China

Qingtian County of Zhejiang Province, China has maintained the traditional rice-fish agriculture for about 2,000 years and formed exceptional cultural heritage based on this kind of production mode, so it was ed by FAO as a pilot site for the rice-fish agricultural heritage systems in 2005. This research has applied the indicators of ecological footprint and biocapacity to monitor the environmental conditions of Qingtian County, aiming to find the impact that the traditional agricultural production mode and the local inhabitants lifestyle have placed on the local environmental conditions as well as the role they have played in maintaining ecological balance, cultural inheritance and regional sustainable development. Results show that Qingtian County is characterized by a nearly breakeven total ecological balance, as opposed to Zhejiang Province, the world and other agricultural regions. However, compared with another rice-fish agricultural region, Congjiang County which enjoys a considerable ecological reserve, Qingtian County has consumed a greater amount of environmental resources. Specifically, about half of the ecological footprint of Qingtian County can be attributed to the cropland （50.8%） while the CO2 area only accounts for 11.2%, which is dramatically different from that of the modern industrialized regions. And a vast of percentage of energy is caused by the combustion of fuelwood which not only requires the land to absorb the CO2 emission it has generated but also occupies the forest where it has been chopped.     

Quantitative evaluation of sustainable development based on ecological footprint method： a case study of Tianjin

Since the coneept of sustainable devetopment emerged in the late 1980s, more and more countries and regions have been utilizing sustainable development as their developing stratety. But decades have passed without any effective methods available to quantitatively assess sustainable development. Since the ecological footprint evaluation method initiated in 1992, it has become popular in quantitative assessment of sustainable development because of its convenience, easy-understanding, and rehability. As one of the biggest coastal cities in north China and the economic center of the Bohai Coastal Region, Tianjin＇s gross domestic product （GDP） was 369. 762 billion yuan in 2005, accounting for 2.0°of the whole nation＇s GDP. The paper analyzes Tianjin＇s development with the ecological footprint method, and the results show that Tianjin＇s ecoiogical footprint and biocapacity in 2005 were 2.507gha/cap and 0.2 76gha/cap respectively. The ecological deficit was 2.230gha/cap.And from 1980 to 2005,Tianjin＇s ecological deficit per 10^4 yuan GDP decreased;while per capita ecological deficit has been tending to increase rapidly in recent years.All these result demonstrate that Tianjin is in a state of unsustainable development.     

Application of ecological footprint in ecological industrial systems：a study case of maize-MSG production systems

To improve the comparability of the research results of ecological industry, the ecological footprint is appliedto analyze the resource utilization and environmental pollution in various subsystems, taking maize-MSG as a case.Results show that the production process from maize to MSG is a extended process of ecological footprint, and that theecological footprint of the maize production is the biggest; the extension of ecological footprint is followed by the increaseof footprint profit, which means that the extension of production chain is an important method to improve the resourcesprofit; the systems have a big proportion of the indirect energy ecological footprint; the air and water pollution in MSGsubsystem is the most serious. At last, it can be identified that ecological footprint is a good method to measure resourceutilization and environmental pollution in various subsystems of an integrated ecological industry.     

Areal differentiation of virtual water for agricultural products and its effect on regional agricultural structure adjustment in China： 1995-2007

With a vast territory, the space-time distribution of water resources is uneven in China. There is a great dif ference in natural conditions and farmland management of agricuttural production in different regions. The areal differentiation of agricultural products virtual water is obvious. Comparison with the agricultural products virtual water from 1995 to 2007 in China shows an increase in the first ten vears and a little decrease in recent years. There has been a tendency of increase all the time in Northeast and Northwest. but a decrease after an increase firstly in other regions. The virtual water offood crops is the maximum which accounts for more than 70% in China. and that of vegetables is in a fast growth. The proportion of agricultural products virtual water to the total water resources in each region has a large difference, showing the imbalance of agricultural water in different regions, which accounts for 50%-90% in Northeast, and 125%-185% in North China. Under the guidance of virtual water strategy, based on the differences of resource endowment, each region should adjust agricultural structure, decide production by water, and select water suitable crops. In water-rich region, agricultural produets of high water consumption should be planted appropriately, which will make full use of the abundant local water resources. In water-shortage region the crop production of high water consumption and low efficiency should be depressed, and that of low water consumption and high efficiency should be supported and increased. It will achieve reasonable disposition of water resources, promote ecological restoration and environmental protection, as welt as ensure food security.     

Comprehensive evaluation of regional ecological security for land use: a case study of Yanchi County, Ningxia Province

As an abstract study conception, most researches of ecological security generally are macro-scale theoretical study with a regional, national or global perspective. Micro-scale research mainly concentrates on ecological risk, ecosystem health and ecosystem safety. In order to assess regional ecological security and to accomplish the transition from micro-scale to macro-scale research, a Driving-Function-State-Output-Respond model framework （DFSOR model） is put forward in this paper according to the analyses on regional population, society, economy resources, environment and ecological risks＇. In empirical research an index system is set out to evaluate ecological security of land use. The DFSOR model comprises five group of indicators： （1） driving indicators, which include social population pressure and economic pressure; （2）function indicators, which include human function, hydrodynamic function, wind function and gravity.function; （3） state indicators, which include soil resources, water resources and land use/land cover; （4） output indicators, which include production output and ecological risk output; （5） response indicators, which are composed of all sorts of policies and measures for improving production of ecosystem. The method and procedure for ecological security evaluation is put forward based on DFSOR model as well. In the case study, Yanchi, the ecotone between agriculture and animal husbandry, is chosen for the study. An index system is built to evaluate ecological security based on the evaluation of regional ecological risks which including sandification, water erosion, soil salinization, soil pollution and shortage of water. The comprehensive evaluation result shows the regional ecological security index of land use in the research area increase obviously. But it is still in the state of low-graded danger.     

Rebuilding water rights system from the perspective of usufruct

As the source of life,water is indispensable to human beings.Being aware of the water stress imposed by population growth,climate change,rapid urbanization,pollution,many scholars and decision makers argue that the establishment of water rights and their system is the primary measure to tackle the water crisis problem.However,no consensus has been reached regarding the definition,nature and content of water rights both practically and academically.By examining the existing theories regarding water rights,this article tries to redefine the entitlements from the aspect of civil law.Meanwhile,it provides a system which classifies various rights by the four functions of usufruct.     

Review on the Study of the Allocation of Corporate Control in Enterprise Theory

With the establishment of a modem corporate system, the separation of ownership and management appears in the company. The rational allocation of corporate control between different behavioral agents has attracted more and more attention. This paper points out that scholars have studied the allocation of corporate control from the angles of the agency cost theory, property rights theory, corporate finance theory, and the theory of corporate governance, which has great value. However, the existing theories also have some flaws on the allocation of corporate control. First, people still have different understandings and views over the meaning of corporate control. Secondly, the existing research theoretically only observes and studies an arrangement of sheer level control, the allocation between final control and real control. This paper argues to build the two-tier allocation of corporate control： The first tier relation is between ultimate control rights and actual control rights, the second tier relation is between indirect control rights and direct control rights which are in actual control rights. This study can explain the resource allocation effects of corporate control, promote the development and improvement of the theory of the firm.     

Conception of Allocating Farming Water Resource with Option System

The uncertainty of natural fall results in the uncertainty of water resource, which brings difficulty in allocating farming water resource characterized by ＂more use when it is lack but less when enough＂. By analyzing the endurance of farming households of water price and the shortcoming of transaction system of farming water fight, options of farming water are deviated from water fight market, which allows farming households to evade the natural and market risks by means of purchasing call or put option contracts in order to raise the utilization ratio of water and to realize the allocation optimum.     

Effect of total resource allocation effect and economic growth：Chinese experience of 1978-2004

The analytical method of total resource reallocation effect is an evolution of the analytical method of the factors of economic growth. Since the marketization reform in China in 1978, market mechanism has played a more and more important role in resource allocation, and Chinese economy has developed greatly, which is called ＂the Chinese Miracle＂. This paper analyzes the economic growth in China from 1978 to 2004 with the analytical method of total resource reallocation effect. The result shows that the annual growth rate of total resource reallocation effect was 0.2%, which was 5.1% of the comprehensive productivity and 0.21% of the gross output growth, i.e. the total resource allocation played a weak role in the economic growth in China. When analyzing it in Chenery＇s multinational model, we find that Chinese comprehensive productivity growth rate was higher than that in all the income phases of the model, but the total resource allocation effect was obviously lower than that in all the income phases of the model. It indicates that the total resource allocation in China has a great potential, and that to accelerate marketization reform is one of the important issues for Chinese economic development.     

Policy of giving rewards and subsidies for grassland ecological conservation in Tibetan Plateau

This paper aims to explore the impact of policy of giving rewards and subsidies(GRS) for grassland ecological conservation in Tibetan Plateau implemented by the Chinese government since 2009.Taking Gerze County in Ngari Prefecture in the Tibetan Autonomous Region(TAR) as an example,it discusses the objective,implementation and outcome of that policy with regard to the ecological reconstruction and problems that have ensured.Located in the northern part of the Qiangtang Plateau,Gerze is the largest county in Ngari Prefecture.It covers more than 7.8 million acres of pastureland,of which 6.2 million acres are usable for pastoralism; 3.4 million acres,however,lack water source.In recent decades,due to the increased population and other reasons,pastures of the area have shown signs of overgrazing,thus leading to serious degradation,desertification and salinization of the grassland.Since 2009,when neighboring Coqin County was chosen as a pilot site for the national ecological incentive and subsidy policy(or: ecological compensation policy),Gerze has also started to adopt this policy and brought ful implementation in 2010.Its purpose is to solve the problem of overgrazing.But like other policies carried out in Gerze,its implementation is faced with many challenges.First,it is difficult to define the types and scopes of the incentives and subsidies,which have become a major source of complaints of the local herdsmen.Second,the local herdsmen are also concerned with the fairness of assigning rewards and subsidies.Third,the high cost of the policy’s implementation and supervision reduces its effects.Fourth,the fact that the herdsmen are not willing to reduce livestock population makes it difficult for the policy to achieve actual results.The author thinks it’s necessary to revise and improve the current ecological incentive and subsidy policy.     

The difficulties of ＂polluter pays＂ policy in agricultural pollution in UK and methods to improve it

Agricultural wastes poll,tion became serious after great improvement in technology and the encouragement of production for the government since the end of the World Wai Ⅱ. Economists and environmental scholars suggested that ＂polluter pays＂ policy be employed in agricultural pollution control. However, it was hard to implement ＂polluter pays ＂ policy alone in agricultural wastes pollution.In practice, there were two social faCtors which contrih,ted to the improvement of water quality in the southwest of United Kingdom. One method is to communicate with farmers and then give farmers some advice or exhortation on facilities and management. The other method is to set up a telephone hotline for public to report water quality and probable pollution. Therefore, the consideration and combination of social factors in the control of agricultural wastes pollution are necessary, and important. Edueation of basic natural sciences relevant to agricultural pollution, system management of agricultural pollutants and laws relevant to agricultural pollution is suggested to be the third .social factor that British government can consider.     

Environment investment： transition from end-investment to multi-investment

Environmental investment must change its direction from end-investment to multi-investment, such as ecological construction, recycling economy and environmental protection. Only it can meet the needs of breaking the bottleneck of resources and environment for Chinese sustainable development. And the transition can hero us realize low-ost and highspeedy increasing of economy, as well as the construction of ecological health, beautiful environment economic development and harmonious new society. Material recycling in ecosystem can run well by self-organization and self-regulation by nature with low-cost and even non-cost. So, the environmental investment in ecological construction should be the profits maximum investment. But it needs country＇s support in financial policy on ecological or environmental compensation. Recycling economy is a brand-new pattern of economic growth, which formed gradually in the course of mankind exploring and practicing sustainable development. Fountainhead prevention, reducing and whole processing control are its significant characteristics, which are digerent from any former economic and environmental protection system. Investing in technology development and relevant industry of recycling economy should be the other major field of environment investment in China in the future.     

Assessment of the immigration effect and choice of development pattern for scenic areas： a case study of Wuyi Mountain, China

Mountainous regions face a series of Conflicts betWeen the natural resources conservation and the economic development, especially in protected areas, where are the home to some of the poorest people in＇the world In China, the Protected Areas Authorities （such as Protected Areas Authorities of Wuyi Mountain） transferred the mountainous people out of the protected areas. We found that it is not a good approach of immigration project, as fal economic and ecological effect is concerned. Although remote and majestic, beauty attracted many tourists, mass tourism is not a good approach to soh,e the development problem in mountainous areas because it can not provide enough opportunites to make local people live a comfortable life, and the high volume of tourists indicates that the resources, face significant threats. Because many fandscapes,are run by Private enterprises, local residents and government only get limited benefits. Alihough ecotourism principles expatiate on economic development and resource, onservation, local people income and tourists feelings, it has discordance between the theory and the praciice Therefore. the term of ＂integrated ecotourism ＂ was coined in the paper.based on the ecotourism theory, Integrated ecotourism means a broadly tourism resources and pendulum spatial pattern which will come into being with the movement of local,people and tourists from protected areas io the nearby town or city： and it also tries to solve the property right conflict of mountain land between the local people and the private enterprises according to property right theory.     

A study of economic development in Tibet of China based on the ecological economic mode

The purpose of this paper is to study the issues on keeping the continuous development of Tibetan economy and the relative stability of its ecosystem. Hence, in order to achieve the object, the study analyzes the status quo of economic development in Tibet and the problems of resource exploitation. It especially discusses frailty of Tibetan eco-environment, and evaluates the contradictions between the traditional economic developing mode and the safety of plateau＇s ecosystem. It concludes that there is an inevitable clash between the development of Tibetan economy and the safety of plateau＇s eco-system; this problem cannot be avoided by any decision maker, Therefore, the character of Tibetan econvironment and the requirement of its economic development strategy determine that ecological economy developing mode is the only choice for Tibet. This paper suggests that it should be compensated by the national government to assure that Tibetan economy can keep a higher developing speed. In accordance with the feature of plateau eco-economy system and demand of Tibetan economic development, this paper also suggests several methods to apply the ecoeconomy developing strategy of Tibet.     

Research on the Development Model of Ecological Agriculture in Loess Hilly-Gully Region of Northern Shannxi, China

On the Loess Plateau of China, facing the vulnerable environment, local people have to try their best to guarantee the security of food, and at the same time, to control the most serious soil erosion in the world. The paper introduces two typical models of ecological agriculture: ecological agriculture with commodity and agriculture with soil and water conservation. According to the local natural condition, the model of eco-agriculture with commodity could be characterized by the structure of “agriculture-byproduct”, “agriculture-fruit” or “agriculture-forestry-husbandry”. The development of agriculture with soil and water conservation has decreased the soil erosion rate from 12, 184 ton/kin^2 in 1980 to 458.4 ton/kin^2 in 1999, while the farmers‘ income has increasingly risen. Analyses on the two models‘ benefits both in terms of ecological and agricultural economy show that there is a great possibility to construct or restore good eco-environment with comprehensive control in the hilly-gully area of north Shannxi. Further more, the paper points out the potential problems of foodstuff production and stockbreeding development in forming ecological agriculture and eco-environmental restoration.     

Economic valuation of gas regulation as a Service by rice-duck-fish complex ecosystem

Valuating the fimction of ecosystem services is crucial for accounting green GDP, making a conservation policy of ecological environment and the decision of regional development as well as sustainable development strategy. R ice-duck-fish symbiosis has been promoted in several developing countries as a way of increasing incomes for rice farmers, but investigations of its value have mainly focused on direct economic＇ benefits, such as food and raw material production. Few studies have been conducted on the estimation of indirect services provided by rice-duck-fish complex ecosystem. The gas regulation service and its economic values provided by rice-duck-fish complex ecosystem were studied in Wuhan, China. The major components of gas regulation are O2 emission and greenhouse gases （GHGs, CO2） regulation. The results show that O2 emission from different treatments （including rice-duck （RD）, rice-fish （RF）, rice-duck-fish （RDF） and rice （CK）） ranged from 26,370 kg/ha to 33,910 kg/ha per year. with an economic value of 10,050-12,920 yuan/ha per ）,ear （Chinese currency： 1 euro =10.2475 yuan, August 28, 2007）. The net GHGs exchange varied from 1,200 to 3,320 kg/ha per year; and its economic value ranged from 1,040 yuan/ha to 2,900 yuan/ha per year Consequently, the total economic value of gas regulation provided by symbiosis complex ecosystems ranged from 11,090 yuan/ha to 15,820 yuan/ha per year. and the maximum overall economic value of gas regulation was provided by RDF complex ecosystem. The work will be useful for further understanding of the functions of rice-duck-fish complex ecos.vstem services and supplying the theoretical references to agricultural policy.
