【摘要】 生态服务功能及其辐射效应的研究是将经济学融入生态学的研究热点。文章评估了吴中区太湖区及其下游各区湿地生态系统生态服务功能价值,界定了生态服务功能辐射类型,运用辐射模型、断裂点模型分析了吴中区太湖区对其下游各区的生态服务功能辐射范围及辐射量,在此基础上尝试性地计算了下游各区的生态补偿分担量。分析得出如下结果:吴中区太湖区及下游阳澄区、杭嘉湖区、浦东浦西区湿地生态系统生态服务功能价值分别为184.9、63.7、61.0、50.7亿元/a,其中旅游功能和航运功能占最大比例;吴中区太湖区湿地生态系统调节功能、支持功能具有辐射效应,辐射价值总量为43.7亿元/a;下游阳澄区、杭嘉湖区、浦东浦西区各区对吴中区太湖区的生态补偿占比分别为18%、81%、1%。更多还原

【Abstract】 The research on the ecological service function and its radiation effect is a hot spot in the research of ecological economics. This paper evaluated the value of ecosystem services of wetland ecosystem in Taihu area of Wuzhong District and the lower reaches of Taihu River Basin,then the radiation types of ecological service function were defined,and the radiation range and radiation strength were calculated by using radiation model and fracture point model, and the ecological compensation of the downstream areas has been calculated. Results showed that the value of Taihu area and its lower reaches of wetland ecosystem service function are 18.49,6.37,6.10,5.07 billion per year,in which the tourism culture function and shipping function value are the largest. Total amount of radiation value of Taihu area of Wuzhong District wetland ecosystem is 4.37 billion per year. The ecological compensation of Yangcheng Lake area,Hangjia Lake area,Pudong and Puxi regions accounted for 18%,81%,1% respectively.更多还原
