| 摘 要： | 为了弄清汉源县的可持续发展现状,根据2003-2007年的统计资料,运用生态足迹模型对汉源县的生态足迹和生态承载力分别进行了分析。结果表明：（1）5a平均生态足迹为0.867hm2/人,年均增长率为3.48%;生态承载力变化不大,为0.311 2hm2/人;平均生态赤字0.513hm2/人,年均增长率为8.69%,处于一种相对不可持续的发展模式。（2）耕地和化石燃料用地占生态足迹的73.44%,说明当地主要通过消耗本地的自然资源来维持区域的发展;耕地供给对生态承载力贡献率为81.09%,供给类型比较单一。

| Abstract: | To understand the status quo of the sustainable development in Hanyuan County,the dynamic analysis had been made separately on the ecological footprint and the bio-capacity of Hanyuan County by using mathematic models,which is based on statistics from 2003 to 2007.The results showed that: first,per capita of ecological footprint was 0.867 hm2 per person in five years,whose annual increase rate was 3.48%;the bio-capacity was 0.311 2 hm2 per person,which had not changed apparently;the average eco-deficit was ... |
