摘　　要：计算分析了肃南县、天祝县2个少数民族自治县在甘肃祁连山自然保护区区域内2009年的生态足迹、生态承载力、生态盈余/赤字和万元GDP生态足迹.在进行生态承载力计算时,根据研究区实际情况,对森林资源二类调查中12类地类按生态足中的6类生物生产性土地进行了重新归类.结果表明:肃南县和天祝县在祁连山自然保护区范围内生态承载力都出现赤字,人均生态赤字分别为3.164 4hm2和0.074 7hm2;由于祁连山保护区所在各县(区)进出口贸易量较小,所以进出口贸易对计算生态足迹的影响较小;2个区域人均万元GDP生态足迹分别为1.983 6hm2和2.175 9hm2,均大于甘肃省2009年的1.902 3hm2;研究区2009年的发展模式处于一种不可持续状态.The ecological footprint,ecological capacity,ecological surplus/deficit and the ecological footprints per 104 yuan GDP of Sunan and Tianzhu County in Qilian Mountains national nature reserve in 2009 were calculated and analyzed.During the calculating of ecological capacity,twelve land groups based on forest inventory were reclassified to 6 class of biological productive land.The results showed that in the research areas,the ecological deficits per capita were 3.164 4 hm2 and 0.074 7 hm2.The import and export trade in the county（district） of Qilian Mountains national nature reserve were relatively small.Thus,the development of the research areas in 2009 was not in a sustaining condition.Ecological footprints per 104 yuan were 1.983 6 hm2 and 2.175 9 hm2 in the research areas,it was higher than the 1.902 3 hm2 of Gansu Province in 2009.
