摘要
选取国家"两型"社会建设综合配套改革试验区为研究对象,采用对比分析法、土地利用类型动态度法、土地利用程度综合指数法、生态系统服务价值当量计算法,探讨两型社会对生态环境的要求和该地区土地生态系统服务价值变化。结果表明,研究区10年土地利用变化主要体现为耕地、水域的减少和林地、建设用地的增加;除建设用地外土地利用总体变化速度较慢;生态系统服务价值量总体下降。价值系数的差异造成土地利用变化产生的生态系统服务价值相互抵消,但生态系统服务价值仍减少,与"两型"社会建设的目标不协调,今后应适当调整土地利用结构。
The effect of land use change was explored on the ecosystem service value at county level of national comprehensive development experimental area by using such methods as combination of theoretical and empirical,dynamic degree of land use,integrated index of land use degree,and ecosystem services value.The results showed that land use change was mainly reflected on the decrease of cultivated land and waters area as well as the increase of woodland and construction land in Liling city from 1996 to 2005.Except construction land,the overall rate of change of land use was slow.Although the value of ecosystem services arising from land-use change caused by the value of the coefficient differences was to offset each other,the value of ecosystem services was dropped.It＇s not coordinate with resource-saving and environment-friendly society.So adjusting land use structure should be pay more attention.However,in the experimental area,ecological protection and resources conservation measures were taken,such as returning farmland to forest and intensive use of land and saving use of land.In the near future,this would be gradually improved,and in line with the requirements of resource-saving and environment-friendly social development.
