摘要
本文以大连旅顺口区为研究区域,采用Constanza生态系统服务价值计算公式,参考谢高地的中国生态系统服务价值当量因子表(2007年),计算得出1994-2008年旅顺口区的生态系统服务价值增加了2383 52万元,较好的实现了经济与生态的协调发展。通过敏感性分析,表明各类土地利用方式对生态系统服务价值变化是缺乏弹性的,其中林地的变化对生态系统服务价值变化起放大作用。
Based on Costanza' s calculation of ecosystem service value and using the coefficients advanced by Xie Gaodi and coworks, who made a table listing the ESV of unit area in land ecosystem and providing the average unit price of ESV in China,this paper calculated the change of the ecosystem service values in 1994 and 2008 of Lvshunkou District,and the results showed the ESV had been changed a little and increased 6.84 million yuan RMB.The sensitivity analysis suggested that the coefficients of sensitivity were all inelastic,and these estimates are relatively reasonable.The change of forest land mainly were influenced the ecosystem function.
