摘　　要：以往国内外关于草地生态足迹的研究都采用牛肉来换算,这种方法对过度荒漠化草原地区来说不太适合。目前国内大多数研究者引用固定转换因子计算生态承载力。应用生态足迹法、"RS"技术及实地调研等方法,通过调整通用产量因子,弥补固定转换因子本身的不足,提高生态足迹模型的区域适合度。在此基础上,开展乡(苏木)尺度生态足迹定量研究。结果显示:2005年各区域生态足迹需求已超出草地生态承载力范围,这表明当地资源利用程度及现有的发展模式已对本地区可持续发展战略的实施构成了威胁。Ecological footprint is always obtained by the conversion of beef.This kind of means,however,is not suitable for the severely degenerated grasslands.At present,most domestic researchers quote the fixed conversion factor to calculate ecological carrying capacity.In this paper,the ecological footprint method,＂RS＂ means and field research are integrated to research the temporal and spatial change of the ecology footprint by taking townships in Plain Blue Banner of Inner Mongolia as the study units based on ecological footprint theory.The deficiency of the fixed conversion factor is improved and the regional suitability of ecological footprint model is increased after adjusting the grassland yield factor.On which the values of ecology footprint in all the townships are calculated and analyzed.The results show that the ecological footprint requirement was exceeded the ecological carrying capacity in all the townships in 2005,which reveals that the utilization degree of local resources and the current development mode have become as a threat to the implementation of sustainable development strategy in the study area.
