摘要
在分析1990～2006年土地利用的数量、结构和程度变化特点的基础上,参考Costanza、谢高地等人的研究成果,结合研究区的实际情况,估算出研究区各年度生态系统服务价值并分析其变化特点及其原因.然后通过敏感性分析,结果表明研究区ESV对生态服务功能价值指数是缺乏弹性的,研究结果是可信的.
Supported by the land use/cover change（LUCC）survey data from 1990 to 2006,the feature of LUCC in Guyuan County have been analyzed.According to partial ecosystem services value evaluation results obtained by Costanza、Gaodi Xie et al and the concrete conditions of Guyuan County,the authors have estimated the economic worth of ecosystem service function of Guyuan County and analyzed the feature and reason of the changes of the economic worth of the ecosystem service function in different periods.The analysis on the sensitive coefficient shows that the ESV is short of flexibility in the study area and the result is credible.
