摘　　要：基于生态足迹模型对杂谷脑河流域发展的可持续性做出评价。结果表明,不同生态生产性土地类型间生态供需差异明显。林地人均生态盈余4.729 5 hm2/人,构成杂谷脑河流域生态盈余的主体,是保障流域生态屏障功能的重要支撑;草地人均生态盈余0.532 3 hm2/人,表明理县畜牧业具有较大发展空间;而耕地出现生态赤字,人均生态赤字0.683 7 hm2/人,表明理县耕地资源相对缺乏的现状。综合林地、草地、耕地、能源用地及建设用地等单因素生态供需数据,经标准化处理,目前,理县人均生态盈余3.793 8hm2/人,整体处于可持续发展状态。Based on the ecological footprint analysis,the article evaluated the sustainable development status of Zagunao River Basin.The results showed that the supply-demands of different ecological productive lands had great defferences.The ecological surplus of the forest lands was 4.729 5 hm2 per capita,which was an important support to guarantee the ecological function for it was the composition subject of the ecological surplus;The ecological surplus of the grass lands was 0.532 3 hm2 per capita,which showed animal husbandry of Li county had great decelopment;However cultivated lands had ecological deficit of 0.683 7 hm2 per capita,it reflected the shortage of cultivated lands in Li county.According to the ecological supply-demands normalized statictics of forest lands,grass lands,cultivated lands,energy lands and construction lands,at present the ecological surplus in Li county was 3.793 8 hm2 per capita,the study area was at the sustainable development status in the whole.
