摘　　要：根据遥感和相关统计数据,运用生态足迹模型和GIS分析方法对塔里木河中下游地区尉犁县农用地的生态足迹、生态承载力和生态足迹变化程度进行了分析。结果表明,1990～2007年,除耕地以外,其他农用地均处于不可持续状态,表现为生态赤字,其中以牧草地的生态赤字最大;农用地总体的生态赤字逐年减小,生态环境有恢复的趋势;1990～2000年,生态足迹的决定因素是牧草地,而2000～2007年,决定因素变为耕地。According to remote sensing data and related statistical data,ecological footprint model and GIS Analysis were adopted to analyze the ecological footprint,ecological carrying capacity and variation degree of ecological footprint of agricultural land of Yuli County located in middle and lower reaches of the Tarim River.Results showed that besides the cultivated land,the other agricultural lands were unsustainable with ecological deficit from 1990 to 2007,in which the ecological deficit of pasture was the maximum.The total ecological deficit of agricultural land was decreasing gradually and ecological environment showed a restoring trend.The decisive factor of ecological footprint from 1990 to 2000 was pasture while that from 2000 to 2007 was cultivated land.
