基于遥感的上海市宝山区海岸带生态资产评估
Assessing the ecological assets in coastal zone using remote sensing data: a case study of Baoshan, Shanghai
摘要
Abstract
With remote sensing data, DEM and meteorological data of the coastal zone in Baoshan, Shanghai, we built a coastal indicators system for ecological assets assessment based on the specific ecosystem service of the area. Moreover, we evaluated ecological assets in coastal zone of Baoshan based on an improved total solar radiation model and an ecological total assets model. The results show that total ecological assets in coastal zone of Baoshan are, respectively, 3. 226 X 109 ￥ , 2. 292 × 109￥ and 3. 075 × 109 ￥ in 1998, 2005 and 2008} it decreases 28. 94% and has an average 4. 13% reduction per year from 1998 to 2005, and increases 34. 16% and has an average 11. 39% rise per year from 2005 to 2008. At the same time, the wetland has dominant contribution for the ecological assets in coastal zone, accounting for 92. 47% in 1998, 89. 91% in 2005 and 92. 92% in 2005, respeclively. With driving force analysis, we find that socio-economic factors like population growth, urban planning, and natural factors such as temperature, precipitation and vegetation, are the main reasons for the change of ecological assets in coastal zone of Baoshan, Shanghai.关键词
