摘要
应用生态足迹模型对白银市2003年生态足迹进行了计算和分析。结果表明:白银市人均生态赤字达1.341 28 hm2,超出生态承载力的186%,处于不可持续发展状态;生态足迹的需求空间以化石燃料用地为主,其需求空间占全部需求空间的65.5%,是生态足迹总供给面积的1.52倍。针对计算和分析结果,提出了城市可持续发展对策。
The ecological footprint of Baiyin city in 2003 was conducted for calculation and analysis by applying the ecological footprint model, The resuits showed that Baiyin city had per capita ecological deficit of 1. 341 28 hm^2, exceeding 186% of the ecological capacity, which was in the unsustainable state. The main requirement room of ecological footprint was fossil energy land, which accounted for 65.5% of the flail demand room, being 1.52 times of the total supply area of ecological footprint.
