Assessment of the agricultural sustainability of Shaanxi Province,China

It is significant for the study on the sustainable development of regional agriculture to monitor and measurethe trend of agricultural development with an effective method. The sustainable development of regional agricultureshould accord with regional population, rural economic development, social progress, resource and environmentalsupport. This paper establishes the evaluating indicators system of sustainable development of regional agriculture,evaluates the agricultural sustainable development in Shaanxi Province with a comprehensive multi-indicator method,analyzes the support of resource and environment for regional agriculture by the resource-development index and theenvironment-development index, and gets the conclusion that the indicators, such as education level, the income gapbetween urban and rural residents, the per capita area under cultivation and the consumption of pesticides and chemicalfertilizers per hectare, are the main factors to restrict agricultural sustainability, and that the pressure of the developmentof subsystems of population, economy and society on the subsystems of resource and environment turns out to bestronger and stronger. Agricultural environment gets better, but resource becomes one of the important factors to restrictthe development of regional agriculture. In a word, this paper highlights the potentials and limitations of sustainableagriculture of Shaanxi and helps identify the development direction in the future.

Research on mechanism of technological diffusion in industry cluster

The main aim of the paper is to explain the reason and mechanism of technological diffusion in industry cluster. Following the idea showed in Zhou Qin＇s model, we further develop the theoretical analysis that how the technological gap between strong enterprises and weak enterprises determines the level and speed of technological diffusion. The bigger the technological disparity between strong enterprise and weak enterprise is, the quicker technology spreads and knowledge overflows; on the contrary, the smaller the technological disparity between strong enterprise and weak enterprise is, the slower technology spread and knowledge overflows. Therefore, this kind of mechanism is helpful for enterprises in an industry cluster to learn from each other and to enable each enterprise close to the ＂the average level＂ of technology or knowledge. As a result, we think that, there exists a close relation between technological gap and technological diffusion. The paper puts forward the way of knowledge overflows of the strong enterprises： imitationdemonstration effect, the longitudinal connection in the industrial chain, the labor force flow and transfer, informal exchange.     

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.

Study on agricultural structure and non-point source pollution： a case in Dapu Town of Yixing City

The water body of Taihu Lake has been eutrophicated because of area-source pollution. 83% of the total nitrogen and 84% of the total phosphorus of the pollutant that have washed into Taihu Lake originated from the fertilizer of crop land, rural animal husbandry and living sewage and rubbish in rural area. The goal of adjusting agricultural structure is to improve agricultural development, and to increase the peasants＇ income by planting non-grain crop, centralizing animal husbandry, and intensifying aquaculture, etc. It is necessary to research on the influences of agriculture industrial structure on area-source pollution. This paper studies a case of Dapu Town in Yixing City, which is a typical drainage place beside Taihu Lake. On the basis of the analysis on the status quo of area-source pollution and agriculture industrial structure in Dapu Town, the conflicts between them are discussed. Non-grain crop production with a great deal of fertilizer and developing aquaculture with a great deal of organic pollutant, which are directly discharged, make area-source pollution more serious and accelerate the eutrophication in Taihu Lake. This paper suggests taking corresponding technological measures and policies, which have been tested in Dapu Town and demonstrated in Taih, Lake area.
