三峡库区土地生态资产价值新评估——以重庆市巫山县为例

On a New Evaluation of Land Ecological Assets in The Three Gorges Reservoir Area——A Case Study of Wushan County,Chongqing

在已有文献的基础上,结合三峡库区实际情况,以重庆市巫山县为研究对象,采用层次分析法确定生态资产价值估算指标体系,并根据巫山县2005年和2012年土地变更数据,对巫山县土地生态资产进行价值估算和评价,得到巫山县2005年和2012年的生态资产总价值分别为50.44亿元和56.98亿元,在此基础上,进一步分析发现林地生态系统对巫山县生态环境重要性最高,其次是水域、耕地、园地、未利用地和建设用地.
