| 摘 要： | 生态足迹作为一种非货币化的生态系统评估工具,是近年来国际上一种重要的判别可持续发展程度的生物物理量方法。均衡因子是生态足迹计算中的一个重要参数,其是否准确直接影响到计算结果的可靠性与可比性。随着生态足迹方法的广泛应用,其标准化和本地化研究成为迫切的需要。为便于区域水平上的生态足迹空间分析,采用中国2001年1km MODIS数据,根据植被的净初级生产力(net primary production,NPP),计算出全国和不同省份各种土地类型的均衡因子。结果表明,就中国平均均衡因子而言,农地和建筑用地为1.71,林地和能源用地为1.41,畜牧地为0.44,渔业水域为0.35;就不同省份而言,由于区域内不同土地利用类型的相对生产能力不同,因而均衡因子各不相同,但大体上呈现农地>林地>畜牧地>渔业水域的规律。

| Abstract: | Ecological footprint(EF),being a kind of non-monetary tool for ecosystem evaluation,has been a major biophysical measuring method used recently worldwide to determine degrees of sustainable development,and has drawn much attention from both domestic and abroad since it was developed by Wackernagel and Rees in 1996.To sum up types of areas different in productivity,equivalence factor was introduced to relate average primary biomass productivities of lands different in land use(i.e.cropland,pasture,forest,fis... |
