张掖市甘临高地区生态系统服务价值变化及其敏感性分析
S tudy on change of ecosystem service value and sensitivity analysis in Gan-Lin-Gao district in Zhangye City
摘要
Abstract
Taking the case of Gan-Lin-Gao district in Zhangye City , the total ecosystem service value in response to land use changes are evaluated by geographic informational system and remote sensing between 2000 and 2007 at temporal and spatial scale . Also the sensitivity analysis is conducted as to the uncertainty on ecosystem service value coefficient and area of different land use type . It is found that arable land and urban construction land expand rapidly but the wetland and grassland resources decrease gradually . And the total ecosystem service value dropped from 57.44 × 108 Yuan in 2000 to 55.31 × 108 Yuan in 2007 . The magnitude amounts to 3.71% . Areas with great changes on ecosystem service value are mainly located in southwest region in the study area . The results of sensitivity analysis are less than one ,which reveal that although there are uncertainty in ecosystem service value coefficient and the digitalization process , the results are still credible .关键词
