基于生态足迹模型,对四川省西昌市土地利用生态承载力进行计算分析,结果表明:西昌市人均生态足迹为0.695541,按12%生物多样性扣除后人均生态承载力为0.610628,人均生态赤字为0.08491;西昌市人均资源利用水平远低于中国人均资源利用率。从生态足迹的组分来看,不同土地利用类型的生态足迹由大到小排序,依次为耕地、化石能源用地、水域、建筑用地、草地、林地;西昌市目前的发展模式主要以消耗自然资源存量为主。
基于生態足跡模型,對四川省西昌市土地利用生態承載力進行計算分析,結果錶明:西昌市人均生態足跡為0.695541,按12%生物多樣性釦除後人均生態承載力為0.610628,人均生態赤字為0.08491;西昌市人均資源利用水平遠低于中國人均資源利用率。從生態足跡的組分來看,不同土地利用類型的生態足跡由大到小排序,依次為耕地、化石能源用地、水域、建築用地、草地、林地;西昌市目前的髮展模式主要以消耗自然資源存量為主。

Based on the ecological footprint mode, the authors calculated and analyzed the land utilization ecological carrying capacity on Xichang city of Sichuan Province. The results showed that the per capita ecological footprint of Xichang City was 0.695541, which dropped to 0.610628 after deducting 12%biodiversity, and the per capita ecological deficit was 0.08491. The utilization level of resources per capita of Xichang City was much lower than that of China. From the compostion of ecological footprint, the ecological footprint of different land use types from big to small order, followed by arable land, fossil energy land, water area, construction land, grassland and woodland. At present, the development mode of Xichang city was mainly to consume natural resource stock.
