生态足迹:测度可持续性的指标框架

Ecological Footprint: An Indicator Framework of Measuring Sustainability

可持续发展定量测度的核心是确定人类是否生存于生态系统的承载力范围之内 .生态足迹是一种定量测量人类对自然利用程度的新方法 .介绍了生态足迹的概念、计算模型、生态足迹模型中使用的生物生产面积类型 .另外 ,阐述了生态足迹指标自身分析的合理性、与可持续发展的相关性、可度量性 .

It is a core of quantitatively measuring sustainable development whether human exists within ecological capacity. Ecolo-gical Footprints are a kind of new method of quantitatively measuring the extent of humanity's use of nature. Here we give an introd- uction to the concept of ecological footprints and computer model, and the types of biologically productive lands. Moreover,its analy- tical soundness, and relevance with sustainable development, measurability are analysed.
