| Abstract: | Wetland ecosystem and resources in Beijing have huge service function, and are very important in maintaining balance of ecosystem and urban ecological security. Because of change of globle climate change and population increaseing of population, area of Beijing wetlands is decreasing sharply, and water is heavily polluted heavily. Service function of wetland ecosystem is degrading by a large margin. Based on remote sensing survey and field investigations, this study has established the classification system, the index system framework and methods of evaluating the serving functions and value of wetland ecosystem in Beijing city with an integrated use of comprehensively applying resource economics and ecological economics methods and then evaluated. tThe service value of wetland ecosystem of Beijing in 2009 was evaluated. In the evaluation, the serving functions of wetland ecosystem were divided into economic service function value, social service funcion value and the ecological service function value. The total wetland area of Beijing in 2009 was 49921.48 hm2 and its total ecosystem service value was quantitatively estimated at 213.7.31 billion Yuan (Chinese RMB), with. The 3.399 billion RMB of economic service function value, 134.094 billion RMB of social service funcion value and 76.238 billion RMB of ecological service function value. They respectively was 33.99 billion Yuan contributed 1.59%, 62.74% and 35.67% toof the total value., among which, fishery value was 10.47 billion Yuan, water supply value was 20.20 billion Yuan and pumped storage power value was 3.32 billion Yuan. The social service funcion value was 1340.94 billion Yuan contributed 62.74% of the total value, among which, culture and travel value was 297.76 billion Yuan, landscape added value was 1042.92 billion Yuan and scientific research and education value was 0.26 billion Yuan. The ecological service function value was 762.38 billion Yuan contributed 35.67%, among which, climate regulation value was 457.73 billion Yuan, water resources conservation value was 91.12 billion Yuan, environmental purification value was 10.06 billion Yuan, biodiversity value was 78.30 billion Yuan, flood control and disaster reduction value was 125.15 billion Yuan, water and soil conservation value was 0.02 billion Yuan. According to the amount of these servicethese services value, landscape added value, climate regulation value and culture and travel value took occupied the main positions in the total value of wetland ecosystem service of Beijing in 2009. These service value results, to some extent, objectively reflected the position and function of wetland ecosystem in Beijing in which served economic development and people's living in the aspects of production, life and ecology city constructiony to some extent and. It canould provide scientific basis for the protection and recovery of wetland ecosystem in Beijing. However, some deficiencies and uncertainties still existed in this study, which should be improved in the future studyies. |
