| 摘 要： | 选择北京市为研究区域,采用1998—2007年的统计年鉴数据,以谢高地等的研究方法为基础,从影响森林资源生态系统服务价值因素的角度,建立修正指标体系,对传统生态系统服务价值测算方法进行修正,分析北京森林资源生态系统服务价值的变化情况。结果表明,北京1998—2007年森林资源生态服务价值总体上呈现先降后升的趋势,引入协调系数修正后的价值也呈这一趋势,但价值量总体降幅为9%。该结果显示在综合了社会和经济因素对森林资源生态系统服务价值的影响因素后,其价值在一定程度上更接近于实际,变化趋势良好。

| Abstract: | An index system for forest ecosystem service value in Beijing was amended by means of influencing factors,according to the data of Beijing Statistical Yearbook and China Forestry Statistical Yearbook from 1998 to 2007.The method proposed by Xie Gaodi was applied to the amendment of the traditional ecosystem service evaluation model,and the change in forest ecosystem service value in Beijing was analyzed.Results showed that the forest ecosystem service value in Beijing first declined and then escalated from ... |
