摘要:
在分析1995-2000年三峡库区（重庆段）土地利用变化的基础上，计算了由此导致的生态系统服务价值变化。采用Costanza的生态系统服务价值计算公式和谢高地等人的中国陆地生态系统单位面积生态服务价值表进行计算，结果发现：1995-2000年研究区林地、草地、水域和难利用地面积在减少，其中草地减少最多，其次为林地；耕地和建设用地在增加，且增加面积都较大；生态系统服务价值（ESV）由1995年的549.387 9亿元减少到2000年的546.706 5亿元，5年减少了2.681 4亿元；敏感性分析表明，ESV对生态价值系数（VC）缺乏弹性，研究结果可信。
Abstract:
Based on the analysis of the land-use change in Three Gorges Reservoir Area (Chongqing) from 1995 to 2000, the ecosystem services value is calculated. The purpose of this paper is to examine the effects on ecosystem services value(ESV) in 1995 and 2000 according to the concrete analysis of the land use of the Three Gorges Reservoir Area (the part of Chongqing).The methods are based on ESV computing formula and ESV coefficients.The result shows that from 1995 to 2000, the area of woodland,grassland,water area and unutilized land decreased,while farmland and built-up land increased, and the total value of ecosystem services declined from 54.387 9 billion yuan in 1995 to 54.670 65 billion yuan in 2000,with the net decline of 0.286 14 billion yuan in 5 years in the study area and the sensitivity analysis suggests that these estimates are relatively lacking in elasticity,so the result is credible.
