摘要
将生态足迹模型应用到三峡库区的可持续发展分析中,选取重庆市忠县作为研究区,对重庆市忠县2005年生态足迹进行定量计算和分析,结果表明:2005年忠县人均生态足迹为1.1415 hm2,可利用人均生态承载力面积仅为0.4635 hm2,生态足迹是生态承载力面积的2.46倍;三峡库区正在通过过度消耗可供利用的自然资源来维持目前的生物生产现状,其发展模式处于一种不可持续的状态。在分析的基础上提出了实现三峡库区可持续发展的措施。
By using ecological footprint model and selecting Zhongxian county of Chongqing city as study zone,this paper discusses the sustainable development capacity through quantitative and analysis on 2005 ecological footprint of Zhongxian county of Chongqing city.The analysis results show that per capita ecological footprint of Zhongxian county is 1.1415 hm 2,per capita utilizable ecological bearing area is 0.4635 hm 2,ecological footprint is 2.46 times of ecological bearing capacity,the present production in TGP reservoir area is maintained by excessive consuming uitilizable nature resources and its development is undevelopable.On the base of analysis,the suggestions for the sustainable development for TGP reservoir area is put forward.
