1. Introduction The mainstream of present economy is the green eco-economy, including green products, green production, green consumption, green market, green industry, and so on. These are the concrete demands of sustainable development for economic life. With the development of economy, society and science and technology and the increase of the population, the abundant ecological resources become more and more scarce [1]. So the quantity and quality of eco- logical resources can’t increasin… 相似文献

1.China's economic development and resources
In the course of world industrialization, resources have been reduced and environment is deteriorating. This results from two factors. One is growth of world population.World population went up to 1 billion in 1800, 2 billion in 1930; accordingly, it cost 130 years to grow 1 billion. And then, it reached 3 billion in 1960, 4 billion in 1975, 5 billion in 1987 and 6 billion in 1999. 相似文献

Recent development in the use of the environmental radionuclide caesium-137 for documenting rates and soil redistribution on the cultivated or uncultivated land and estimating rates of sediment deposition on represents an important advance that overcomes many of the limitations of the conventional techniques commonly applied in such investigations. A study on soil redistribution (including soil erosion and deposition) was carried out in the Dian Lake catchment, Yunnan Province, using ^137Cs and selected chemical properties. The average soil erosion rate was 1,280.2 t km^2 yr^-1. Soil erosion rate occurring on different parts of the slope was significantly different on different parts of the slope, increasing.from the top. the bottom to the middle slope. The average soil erosion rate is also different with the land use type and that of the cultivated land (1, 672. 8 t km^-2 yr^-1) is higher than oJ the uncultivated land (1.161.2t km^-2 yr^-1 ). The result shows that landform, slope gradient and land use type are key factors that influence the size of soil erosion. In addition, we also find the SOC and TN contents and amount of the soil erosion to be correlated in the soil. With the soil erosion occurring, there are land degradation and the local eco-environmental problems, such as water eutrophication in Dian Lake. 相似文献

1. Introduction Studies on land eco-recovery and ecology re- construction emerged in1960s in the world, but it didn't begin until 1980s in China. Actually, the stud- ies on land recovery and ecological reconstruction began in China in 1990s. Many large progresses have been made in the study on the theory of eco- logical recovery of disused land in recent 10 years [1-3]. According to the characters of terrene and min- eral resources, the research areas of ecological re- covery consist of: (1) … 相似文献

Each nationality has formed unique ethnic culture in the long history. Ethnic culture is spatially reflected byethnic distribution. The distribution of nationalities is influenced by ethnic history, culture, society and religion, alsoaffected by regional physical setting. This paper analyzes the relationship between ethnic distribution pattern and naturalsetting with contrast analytical method. The digital elevation model (DEM) is established on basis of contour map on ascale of 1:250,000 in the Nujiang River basin, Yunnan Province by ArcGIS, a Geographic Information System (GIS)software. Based on DEM, the spatial analysis and statistical function of GIS, the landscape patterns of populationdistribution of the selected minorities is described, and 4 sub-regions are divided in the Nujiang River basin of YunnanProvince while the features and disparity of landscape pattern and its forming mechanism are discussed, along withhistorical and archaeological data. The conclusions are as follow: (1) The ethnic distribution is mosaic in the matrix ofother racial distribution, and have a distinct spatial correlation. (2) For the difference in cultivation between differentnationalities, certain nationality lived in the area suitable for production mode of its own and coincident with appropriategeographical setting. (3) The spatial distribution of settlement spots of the minorities is controlled by the convenience ofwater supply. The landscape pattern of ethnic distribution is closely relative to natural environment. 相似文献

Birdwatching tourism can be a good model for nature conservation and economic development if it is managed with the well-being of local ecosystems and human communities. Birdwatchers can bring financial sources to local nature conservation. Many communities and local leaders consider birdwatching as a significant mean to develop local economics and publicize regional image, but only few research have tried to study the impacts of relevant activities on destinations. The purpose of the paper is to give a comprehensive review on impacts of birdwatching from conservation economics and biology perspective. Use a behavioral approach study impacts of birdwatching tourism on environment and economy. Specific objectives here are: (1) review the value and significance on environment and economy; (2) economic potential of non-residential birdwatching for community-based conservations; (3) using a behavioral approach, combine quantitative and qualitative methods study birdwatching impacts; (4) outline the economic and environmental benefits and problems associated with the activity; and (5) aid community leaders and tourism business related company in their efforts to improving the value of birdwatching; help the leaders of natural reserve areas develop birdwatching tourism. 相似文献

This paper discusses the model construction and the association between the Italy and the Germany's stock markets. The period of study data is from January 3, 2000 to June 30, 2008. This paper also utilizes Student's t distribution to analyze the proposed model. The empirical results show that the two stock markets are mutually affected each other, and the dynamic conditional correlation (DCC) and the bivariate asymmetric-GARCH (1, 2) model is appropriate in evaluating the relation between them. The empirical result also indicates that Italy and Germany's stock markets show a positive relationship. The average value of correlation coefficient equals to 0.8424, which implies that the two stock markets return volatility have a synchronized influence on each other. In addition, the empirical result also shows that there is an asymmetrical effect between Italy and the Germany's stock markets, and demonstrates that the good news and bad news of the stock returns' volatility will produce the different variation risks for Italy and the Germany's stock price markets. 相似文献

The basis of community participation of ecotourism in Shangri-La Tibetan area In 1980, the Canadian scholar Clande Molin put forward community participating ecology and cul- ture tourism in his academic thesis [1]. Based on this, Mexico scholar H. Ceballos Lascurain first used the term “ecotourism” in his book in 1983, and was con- firmed by International Environment Conference in Mexico 1986[2]. In 1993, the Ecotourism Society re- defined ecotourism and pointed out its two impor- t… 相似文献

Economic globalization has promoted the formation of global production network, and correspondingly the high-quality environmental factors are reconfigured behind the physical commodities exchange. Export trade not only drives China's economic growth, promotes industrial upgrading and technological progress, but also may have a negative impact on the environment. After reviewing and summarizing the existing relevant literatures, tire paper collects the required statistic data from 2003 to 2006 and uses the panel data model to measure the environmental effects of export trade in the Yangtze River Delta. The results show that the export trade of Yangtze River Delta has a negative impact on the environment. When the variables of economic scale, economic structure areftxed, with the export trade growth of 1%, the industrial sulfur dioxide emission and industrial waste water emtsston will increase by 0.12% and 0.23% respectively. So we must pay serious attention to the negative effects, and promote regional sustainable development rapidly through adjusting the export structure and strengthening environmental regulations. 相似文献
