基于GIS和RS的上海市近海岸生态系统服务价值评估

以2010年上海市遥感影像数据为主要数据源，利用GIS和RS技术，获取上海市近海岸土地利用类型空间分布信息。基于供给、 调节、 支持和文化服务四种生态系统服务类型，确立上海市近海岸生态系统服务体系；采用气候生产力修订单位生态服务价值当量因子的经济价值，从而评估上海市近海岸生态系统服务价值。研究表明：2010年上海市近海岸生态系统服务价值总量为373.32亿元，其中湿地的生态系统服务价值最高。从服务功能角度出发，调节服务功能的生态系统服务价值最高，占总量83.22%。

Valuation of Ecosystem Services in Shanghai Coastal Zone Based on GIS and RS

Based on the remote sensing image of Shanghai in 2010, using GIS and RS technologies, the spatial information of land use in Shanghai coastal zone is achieved. The ecosystem services value system in Shanghai coastal zone is established based on the four first-level service categories: provision services, regulating services, supporting services and cultural services. And then the ecosystem services values in Shanghai coastal zone are evaluated, using the revised economic values of the coefficients of the ecosystem services value that are revised by the climate productivity. The results showed that: the total ecosystem services value in Shanghai coastal zone in 2010 is 37332 millions. The ecosystem services value of the wetlands is the highest. And the ecosystem services value of urban lands is the lowest. The value of regulating services is the highest, which occupies 83.23% of the total ecosystem services.
