摘要

摘要: 运用上海市宝山区海岸带遥感数据、DEM数据和气象数据，基于研究区域生态系统服务功能具体情况建立了海岸带生态资产评估的指标体系.利用改进的月总太阳辐射模型和基于遥感的生态资产计算方法，对宝山区海岸带的生态资产进行了评估.结果表明：1998年、2005年和2008年上海市宝山区海岸带生态资产总量折合人民币分别为3.226109元、2.292109元和3.075109元;1998年到2005年减少了28.94%，年均减少4.13%；2005年到2008年增加了34.16%，年均增加11.39%.湿地在海岸带生态资产总量中具有巨大的贡献，1998年占92.47%，2005年占89.91%，2008年占92.92%.驱动力分析表明：人口增长、城市规划等社会经济因素和气温、降水、植被覆盖等自然环境因素变化是影响宝山区海岸带生态资产变化的主要因素.

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, 3.226109 ￥, 2.292109 ￥ and 3.075109 ￥ 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.
