【摘要】 为了探究土地利用变化与生态系统服务价值的关系,本文以2007年和2015年重庆市沙坪坝区的TM影像为基础,以量化方法对生态系统服务价值的评价与土地利用变化的信息进行分析。结果表明,重庆市的耕地、林地、水域等面积均在减少,建筑用地的面积却不断增加。从动态度的角度分析,变化幅度最小的区域为林地,变化指数为-0.13;变化幅度最大的区域为建筑用地,变化指数为0.13。下降明显的指标为生态服务总价值,从2006年的11.27亿元减少到2015年的7.77亿元。敏感性分析表明,ESV对生态系统价值系数缺乏弹性,结果具有可信性和参考性。更多还原

【Abstract】 In order to explore the relationship between land use change and ecosystem service value, this paper analyzes the evaluation of ecosystem service value and land use change information by quantitative methods based on the TM images of Shapingba District in Chongqing in 2007 and 2015. The results show that the area of cultivated land, forest land and waters in Chongqing is decreasing, and the area of construction land is increasing. From the perspective of dynamic degree, the area with the smallest change is forest land, and the change index is-0.13; the area with the largest change is construction land, and the change index is 0.13. The obvious decline in indicators is the total value of ecological services, from 1.127 billion yuan in 2006 to 777 million yuan in 2015. Sensitivity analysis shows that ESV lacks flexibility in the ecosystem value coefficient, and the results are credible and informative.更多还原
