2003-2007年广州市生态足迹动态研究

The Dynamic Study of Ecologic Footprint from 2003 to 2007 in Guangzhou City

生态足迹是近年发展的用于定量研究和判断一个国家或地区可持续发展状况的新方法。本文在简要介绍生态足迹的概念与计算模型基础上,定量研究了广州市2003年-2007年五年间的生态足迹和生态承载力变化规律和特征,并分析其原因。结果表明:五年间广州市人均生态足迹分别为2003年1.701 6 ha,2004年1.930 9 ha,2005年2.039 3 ha,2006年2.095 8 ha,2007年2.247 1 ha;人均生态承载力依次为2003年0.263 2ha,2004年0.259 1 ha,2005年0.253 9 ha,2006年0.238 7 ha,2007年0.216 2 ha;生态赤字呈逐年增加的趋势,从2003年的1.438 4 ha上升到2007年的2.030 9 ha,根据计算得到的广州市生态赤字的现状值,分析了生态赤字的成因,为广州市可持续发展提供生态承载力的参考指标。

Ecological Footprint Analysis is a new method which has been developed in recent years for quantitative study and judging the sustainable development of a country or region.The paper quantitatively studied the ecological footprint and ecological capacity and features of variation of Guangzhou between the year 2003 and 2007 on the basis of briefly introducing the concept of Ecological Footprint and calculation model,and also analyzed the cause of changes.The results showed that：the per capita ecological footprint of Guangzhou was 1.701 6ha for 2003,1.930 9 ha for 2004,2.039 3ha for 2005,2.095 8ha for 2006,2.247 1ha for 2007;The per capita ecological carrying capacity was 0.263 2ha for 2003,0.259 1ha for 2004,0.253 9 ha for 2005 years,0.238 7ha for 2006,0.216 2ha for 2007;The ecological deficit was gradually increased,from 1.438 4 ha in 2003 up to 2.030 9 ha in 2007,according to the calculated ecological deficit in Guangzhou,the paper analyzed the causes of the ecological deficit and provided the reference index of ecological carrying capacity for the sustainable development of Guangzhou.
