摘　　要：巫山县地处三峡库区的腹心地带,三峡水库蓄水后,人地矛盾将更加尖锐。以巫山县为研究对象,运用生态足迹模型对巫山县2006年生态足迹进行定量计算和分析,结果表明:2006年巫山县的人均生态足迹为1.296 9 hm2,可利用的人均生态承载力仅为0.559 2 hm2,人均生态赤字高达0.737 7 hm2。其中,生态赤字部分主要来源于耕地产品、草地类产品和能源的消费。可见,巫山县的人类社会活动对自然资源的消耗已经超过了巫山县生态系统的承受能力,区域发展处于不可持续状态。并在结果分析的基础上提出了实现巫山县可持续发展的措施。Wushan county is located in the central region of the Three Gorges Reservoir area.When the Three Gorges Reservoir impounds,the contradiction between people and land in the Three Gorges Reservoir area will become even more acute.Taking Wushan county as the research object,counting and analyzing the ecological footprint of Wushan county in 2006 based on ecological footprint model.The result shows that： its per capita ecological footprint is 1.296 9 hm2,available ecological capacity per capita is only 0.559 2 hm2,and per capita ecological deficit is as high as 0.737 7 hm2 in 2006.Among them,the major ecological deficit of products derived from cultivated land,lawn land and energy consumption land.Thus,human＇s consumption of natural resources in social activities exceeded the capacity of ecosystem in Wushan county,its regional development is unsustainable.On the base of analysis,the suggestions for the sustainable development of Wushan county is put forward.
