基于生态足迹与生态承载力的城市可持续发展分析——以成都为例

摘要

应用生态足迹和生态承载力的数学模型,计算了成都市2009年生态足迹和生态承载力。结果表明,成都市生态承载力远小于生态足迹,导致生态赤字巨大,其中人口的过快增长,对生态环境造成了巨大的压力,同时也是成都市可持续发展的主要阻碍。在此基础上,进一步揭示了成都市人多地少的尖锐矛盾,并对成都市的可持续发展提出了合理的建议和对策。%By applying mathematical models of the ecological tracks and ecological bearing capacity,this paper caculated the ecological tracks and ecological bearing capacity of Chengdu city in 2009.The result showed that the ecological bearing capacity in Chengdu city is far less than its ecological tracks,leading to the huge ecological deficit.Among them,the overspeeding increase in population created great pressure for the ecological environment,and meanwhile,it is the main impeding for the sustainable development of Chengdu city.Based on this,this paper further disclosed the intense contradiction with more people and less land in Chengdu,and proposed some reasonable suggestions and measures for the sustainbale development in Chengdu.
