基于生态系统服务功能价值理论的土地利用总体规划环境影响评价探讨——以湘乡市为例

Environment Impact Assessment of Overall Planning of Land Use Based on Biological System Service Function Value Theory

在应用Costanza、谢高地等对生态系统服务功能价值研究成果的基础上,结合区域实际情况确定湘乡市各种土地利用生态系统的单位面积服务功能价值,根据湘乡市规划期内各种土地利用类型的面积变化,预测湘乡市新一轮土地利用总体规划实施前后土地生态系统服务功能价值的变化,评价规划实施后将产生的生态环境影响,引入弹性系数对生态价值的敏感性指数进行计算。实现了土地利用总体规划环境影响定性分析与定量分析的结合,对制定正确的土地利用决策具有重要而深远的意义。

Ecosystem Services values was applied to assess the environmental impact assessment of the land-use master planning by calculating the ecosystem services value of actual and future land use types in Xiangxiang.In order to minimize the impact to the result of assessment by adjust coefficient of ecosystem services values,the sensitive coefficient was applied.The introduction of the theory of ecosystem services value realizes the combination of qualitative analysis and qualitative assessment of environmental impact of land-use master planning.It is significant to the revision of the land-use master planning.
