摘要
分析土地利用变化数据,采用土地利用动态度,结合谢高地等的单位面积生态服务价值表,评估上轮规划实施期间道县土地利用变化引起的生态系统服务价值的变化。研究表明,区域土地利用变化对生态系统服务价值有重大影响,要加强研究优化土地利用结构的措施,确保经济发展的同时环境不恶化。
Based on the Constanza＇ s ecosystem service value theory and coefficients advanced by Xie Gaodi, who made a table listing the ecosystem services of unit area in land ecosystem and provided the average unit price of ecosystem services in China, this authors calculate the change of the ecosystem service values in 1996 and 2005 of Daoxian County, Hunan Province on ecosystem respectively. The results have been concluded as follows ： the change of regional land-use has great impact services value, it is necessary to strengthen study of measures for optimizing land-use to ensure the economic development without environmental degradation
