摘　　要：基于改进的生态足迹模型,分析了石羊河流域生态经济系统2001～2007年的生态供需状况、可持续发展及发展能力。结果表明,生态盈亏表现为生态赤字,供需矛盾尖锐,生态环境处于不安全状态,但生态赤字缓慢下降,说明生态环境有所改善。同时,可持续发展指标较低,生态-经济处于极不协调的状态,生态足迹多样性指数和发展能力几乎没有变化,石羊河流域实现可持续发展的任务依然艰巨。Ecological supply/demand,sustainable development and development ability of Shiyang River Basin 2001-2007 economic system were analyzed with the improved model of ecological footprint.The results show that the ecological gains and losses performance of ecological deficit,the supply and demand contradiction,the ecological environment are not safe,but slow decline in ecological deficit shows that the ecological environment has improved.At the same time,sustainable development indicators low,ecological economy is far from the coordination of state,the ecological footprint diversity index and the development capacity is almost no change in Shiyang River Basin is still arduous task of achieving sustainable development.
