鄱阳湖流域生态足迹与生态环境协调度的计算与分析

生态足迹是一种基于消费度量区域是否可持续发展的新参考方法,而经济与环境协调度从横向角度衡量可持续发展。本研究介绍了生态足迹的概念及生态足迹和生态环境协调度的计算评价方法,并对鄱阳湖流域2003年的生态足迹和生态环境协调度进行了计算和分析。结果表明,2003年鄱阳湖流域存在生态赤字,人均生态协调系数DS=1.3802<1.414,生态环境协调度为43,表明本地区2003年的发展模式是基本不协调和基本不可持续的。

Calculation and analysis of ecological footprint and ecological environment coordination degree of Poyang Lake area

Ecological footprint is a new reference method based on the consumption to evaluate the sustainable development of an area,while the ecological coordination degree assesses the sustainable development of an area transversally.The concept of ecological footprint,the calculation methods of ecological footprint and the ecological coordination degree are introduced in this paper.And the calculation and analysis results of the ecological footprint and the ecological coordination degree of Poyang Lake area in 2003 are presented.The results show that there is an ecological deficit in Poyang Lake area in 2003 and the ecological coordination quotiety is 1.3802,the ecological coordination degree is 43 showing that the development of Poyang Lake area is not coordinated and not sustainable.
