| Natural resource is the cornerstone of human civilization. The development of human economics and social system depend on the continued use of natural resources. In 1970s, the idea "the depletion of natural resources" proposed by Rome Club has triggered the research on the supply and necessity of natural oil and other important resources of energy supply and demand, leading to the social concern about natural environment. In 1990s, whether resources can be used sustainably has caused great attention of resources in the society.This paper mainly focuses on An Ji County, which lies in the west of the Yangtze River Delta, one of the most well- developed economic regions in China. According to the preliminary exploration, the main reasons why An Ji County can gain similar economic growth amongst Changjiang Delta and maintain an environment-friendly ecological environment will be listed below. First, An Ji County possesses special ecological resources advantage. The methods formed during historic evolvement to use resources fit the characteristics of natural elements in different elevation distribution and fit the production and lifestyles of ecological resources evolution. Second, the residents pay their attention to the distribution of resource profit. Third, the local government promotes ecological construction for the county. These three reasons are the indispensable foundation to carry our sustainable development for the county.This paper is based on field survey data collected for more than two years, and utilizes the application of satellite remote sensing technology and GIS analysis methods and distills elevation distribution distribution for ten types of land-use patterns, including eight species of ecological resources, rural land-use and unused land.. Emphasis is laid on the value of eight ecological resources in An Ji County amongst twelve types of ecological service types , including net plant productivity, fixing carbon-dioxide and releasing oxygen, air purification, water conservation, soil formation and retention , nutrient cycling, waste treatment, food production, biodiversity, entertainment and culture, plus the different distribution of each service value in different elevation distribution. The total service value of ecosystem in An Ji County is 5.5 billion yuan, which is lower than its actual GDP value in 2002, 6.125 billion yuan. Judging from the relative research achievements from home and abroad, the main reason that causes the low service value of ecosystem is due to the limited research conditions and relatively little investigation contents.By means of comparison analysis of the field survey data, we got the TSV and the corresponding GDP value as well as the distribution in different elevation distribution of eight ecological resources, ten special physiognomy resources and county land use. We conducted the analysis on speciality of the coupling status quo of regional economics and all natural resources as well as the initial analysis on the relationship between regional economics and eight ecological resources coupling. We also completed the analysis on coupling of regional economics and natural resources of An Ji County in 2006 via the recent data collection. We found out that the key way to increase economy in An Ji County is to attract external resources and conduct intensive production by developing land use in the recent four years. We got the coupling model of regional economy and all natural resources, including the model of TSV distribution of natural resources and coupling GDP model of regional economics and all natural resources. We estimated the distribution of TSV and GDP elevation distribution of the year 2010, 2015, 2020, 2030, 2040 and 2050 with the current developing method as well as the total change of TSV and GDP via the models. With the continuous economic development, GDP increased rapidly as the sign of regional economic development with the increasing rate between 10% and 12%. However, TSV, the economic value of local natural resources transform, increased relatively slowly with the increasing rate between 2. 5% and 6. 3%. The difference between the growth rate indicated that the growth of different connotations of the growth difference is enormous. Meanwhile, we could conclude that the current economic growth pattern in An Ji County is not sustainable.In order to achieve the sustainable development in An Ji County, the current mode of economic growth must be changed to carry out ecological compensation. Direct ecological compensation will accord with the actual situation of compensating ecological protection areas' economic expense. However, it' s hard to implement regional compensation. Currently, central government will provide the direct financial compensation. Indirect compensation is relatively effective only in the overseas private enterprises with clear anticipation and transparent property rights and profit margins. An Ji County is located in developed area, and is centralized by government organizations with advanced concepts and high income people and highly educated groups. The regional community as a whole has better awareness and consciousness of environment protection and ecological value concepts, which could lead to tremendous consuming market with oriented significance. Only on the basis of win-win ecological compensation can ecological conservation areas be protected. It's the same with people's mentality. Moreover, it's possible to make the maintenance of ecological resource value be the core requirement of local citizens to gain economic profits, thereby improving the protection of ecological resources. This paper raised the theory of win-win ecological compensation first independently, which could not only make up for the inadequance of direct and indirect ecological compensation, but also increase the income of local citizens and improve the life quality. Thus we could reach the purpose of environment protection and ecological quality maintenance.The implement of ecological compensation strategy can be realized by means of changing the parameter of model which is used to forecast the future development. On the basis of maintaining the GDP growth rate, the TSV growth rate of ecological resources in An Ji County keeps growing. Its TSV growth rate will exceed its GDP growth rate after the year 2030, which fully demonstrated the possibility of maintaining ecological resources and gaining long-term profit via providing ecological services.We posted the essence difference between maintaining the existing economic growth method and a win-win implementing ecological compensation model in sustainable development via suitable discounting of gross economy in the near future. If we keep the current economic growth mode, its TSV growth rate will only account for 4.4% of ecological service value and its corresponding GDP will only account for 16.4% of ecological service value. In this case, An Ji County will have to rely largely on foreign investment and market and labor resources to keep its development, which will not be sustainable development. However, if we implement a win-win strategy for ecological compensation, TSV will increase year after year and finally account for 128.6% of local ecological service value, which indicates that the basic survival information such as air, water and food exceeds the special ecological value of survival information in city. This value will be returned to residents via win-win ecological compensation, and thus safeguarding the sustainable development in An Ji County.If we carry out the dimensional comparison analysis of TSV, GDP and the ecological service value under the win-win ecological compensation model as well as the existing economic growth mode, we can figure out the differences more clearly. The ratio of TSV and ecological resource value and the ratio of GDP and ecological resource value under the model of maintaining current economic growth method was less than 30% in the year 2002. The higher the altitude is, the lower the ratio will be. The total proportion in elevation distribution will be less than 15% in the year 2050. If we implement the win-win ecological compensation model strategy, the economy development between 2002 to 2006 and between 2040 to 2050 will be totally different. The characteristics of TSV and GDP from ecological resource transform are absolutely different. The proportion of ecological resource transform will exceed 100% below 1,000 meters elevation distribution in 2050. The ecological value of resource and service in the areas with higher altitude has not been fully excavated yet.
