生态足迹理论的微观分析-成分法的算法及应用

The arithmetic and application of component-based methodology: micro-analysis of ecological footprint theory

随着可持续发展研究不断深入,生态足迹理论逐渐成为国内外可持续发展量化研究的热点。成分法作为生态足迹分析模型中应用于微观单位的一种算法,能够较为简便形象地估算微观单位对各种资源的消耗程度,为制订可持续发展战略提供理论依据。该文对该算法的基本思想、分类方法、计算方法和优势缺陷等进行了介绍。同时,利用成分法进行生态足迹分析尚需根据国情进一步完善和加强,在我国应用生态足迹的成分法分析模型的主要困难是数据的收集和均衡因子的取得,但根据我国可持续发展的战略性需求,成分法分析模型必将得到广泛应用。

With the deepening study of sustainable development, the theory of ecological footprint （EF） has become a focus in the quantitative research of it. As a methodology for micro-analysis of EF, the component-based EF （CEF） can be used to estimate the consumption degree of resources in micro-units conveniently and visually, so as provide the theoretical foundation for the formulation of sustainable development strategy. In this thesis, the basic concept, way of classification, methodology, advantages and shortcomings of the CEF will be stated. Meanwhile, the difficulty in acquiring data and equivalences in China should be considered too. It is indicated that ecological footprint theory and component-based methodology will be wildely used in future.
