基于生态足迹模型分析了湖北省1991-2011年耕地生态足迹、生态承载力及生态赤字,并且使用ArcGIS软件分析了2011年湖北省17个市（州）耕地生态足迹的空间分异规律,在此基础上,基于生态可持续指数（ESI）对湖北省耕地利用状况进行了评价。结果表明,湖北省耕地生态足迹不断增加,而生态承载力逐年下降,耕地的生态赤字呈波动增大趋势,全省耕地属于弱不可持续类型;湖北省耕地生态足迹可持续状况的空间分异表现在东西两端好于中部,神农架林区和恩施自治州生态盈余分别为0.289 0 hm2/人和0.096 0 hm2/人,耕地属于强可持续和弱可持续类型;西部的宜昌和十堰,东部的黄石和咸宁都较好;中部地区的荆门、天门、...

Based on the ecological footprint model and dynamic characteristics, the ecological footprint, ecological carrying capacity and ecological deficits of arable land in Hubei province (1991-2011) were analysed. Spatial variation regulars of ecological footprint of arable land in Hubei province (17 cities) in 2011 were stedied using the ARCGIS software. Pased on ecological sustainable index (ESI), utilization status of cropland in Hubei province was evaluated. The results showed that ecological footprint per capita of cropland in Hubei province was increasing, but ecological carrying capacity decr...
