摘　　要：本文基于生态足迹计算模型,以2003年开县生态足迹和生态承载力的计算为基础,计算并分析了开县2003—2006年的生态足迹和生态承载力,对开县的土地承载力和社会经济发展的可持续性作出了评价.从2003年的数据计算结果来看,消费和产业结构单一是造成开县生态赤字的主要原因.从时间序列上看,开县的生态足迹连续多年高于生态承载力,人均生态承载力基本保持稳定在0.426 538~0.434 438 hm2之间,但生态足迹却呈现较大的波动且与耕地的生产性土地面积的波动以及生态赤字的波动趋于一致.开县生态赤字严重,处于不可持续的发展状态,主要原因是开县经济对农业的依赖过强.This study calculated and analyzed the ecological footprint of Kaixian county from 2003 to 2006 based on ecological footprint model.According to analysis of the data in 2003,it is concluded that the oneness of the consumption structure and industry structure was the main cause of ecological deficit in Kaixian county.In addition that,although the ecological footprint fluctuated drastically,it appeared that eco-capacity of this district stayed stable between 0.426 538 hm2·cap-1 to 0.434 438 hm2·cap-1.Development of society and economy in this area was generally in an unsustainable condition,which can be attributed to its excessive dependent on the agriculture.
