由于三峡工程的开工建设,巫山县大量移民就地后靠,土地所承载的压力剧增,阻碍了巫山县社会经济的可持续发展。利用生态足迹原理和模型对巫山县2005~2010年土地生态承载力进行分析,并运用相关分析、主成分分析等方法将生态足迹指标与传统经济指标相结合,分析了巫山县社会经济的发展对生态足迹的驱动作用,为巫山县的生态建设及可持续发展提供依据及参考。结果表明:巫山县生态足迹呈现逐年增加的趋势,且近几年增加速度明显加快,而生态承载力则基本持平,人均生态赤字由2005年的1 336 2 hm~2 增长至2010年的2 194 2 hm~2,说明巫山县对自然资源的消费远远超过了区域所能提供的资源供给,阻碍可持续发展...
