| 摘 要： | 根据安宁市2003～2009年土地利用变更调查数据,采用Costanza等专家提出的生态系统服务价值计算方法和谢高地等提出的中国不同陆地生态系统单位面积生态服务价值表计算安宁市2003～2009年生态系统服务价值并对其进行评价。结果表明2003～2009年安宁市生态系统服务价值总量减少了0.24亿元,主要原因是建设用地占用了大量的林地和耕地等生态用地,因此在安宁市的新一轮规划中应注重对生态用地的保护,确保生态系统的稳定。

| Abstract: | Based on the ecosystem service value calculation method proposed by Costanza and Chinese ecosystem services value unit area of different ecosystem types proposed by Xiegaodi,with the land use change datas of AnNing between 2003 and 2009,this paper calculated the ecosystem service value of Anning between 2003 and 2009.The result showed that the totalecosystem service value of Anning reduced 0.24 billion yuan,the main reason is lots of forest land and farmland changed into construction land,during new programming the protection of ecological land must be taken into accounted to stabilize the ecological system. |
