测度可持续发展指标的探讨--以生态足迹方法为例

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.　通过介绍生态足迹的概念、计算模型、生态足迹模型中使用的生物生产面积类型,计算出了韶关市2002年的生态足迹.　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,提出了进一步完善该模型的思考方法.

Study on Indicators of Measuring Sustainable Development Method of Ecological Footprint

It is a core of quantitatively measuring sustainable development whether human exists within ecological capacity. Ecological Footprints are a kind of new method of quantitatively measuring the extent of humanity's use of nature. Here we give an introduction to the concept of ecological footprints and computer model, and the types of biologically productive lands. Shaoguan's ecological footprint in 2002 is calculated. Moreover, its analytical reasonability, relevance with sustainable develop- ment, and measurability are expounded. It is put forward that the model should be perfected further.
