摘　　要：应用生态足迹模型对西昌市1985—2005年的生态足迹进行计算,结合土地利用转移矩阵,剖析了西昌市20a生态足迹动态变化的空间表现,以及生态承载力变化和对可持续发展的影响。结果表明:1985—2005年人均生态足迹总平均从1.1753hm2.人-1增加到5.2479hm2.人-1;除建设用地人均承载力上升,耕地、林地、草地、水域人均承载力均下降,总人均生态承载力从1985年的1.0372hm2.人-1下降至2005年的0.7769hm2.人-1;人均生态赤字呈现显著上升,生态足迹的供需矛盾十分突出,处于不可持续的状态;万元GD,P生态足迹呈下降趋势。The dynamic changes of ecological footprint and ecological carrying capacity in Xichang from 1985 to 2005 were analyzed by means of transfer matrix of land use and ecological footprint model. Results show that per capita ecological footprint in Xichang increased greatly from 1.1753hm^2 in 1985 to 5.2479hm^2 in 2005. Per capita ecological carrying capacity of cultivated land,forest land,pasture,water area all declined except that of construction land. Per capita ecological carrying capacity decreased from 1.0372hm^2 in 1985 to 0.7769hm^2 in 2005. Per capita ecological deficit increased greatly,which reflects that the regional ecosystem is under great pressure and the regional economic development of Xichang is far from sustainable. The demand for ecological footprint for ten thousand yuan Gross Domestic Product （GDP） of Xichang exhibited a decreasing tendency.
