摘　　要：用生态足迹与生态承载力方法计算结果表明,2 0 0 4年草海流域人均总生态足迹为2.7 2 8 hm2/人,生态承载力为0.0 5 8 hm2/人,生态赤字高达2.6 7 0 hm2/人。从动态变化来看,2 0 0 0～2 0 0 4年草海流域人均总生态足迹呈逐渐上升的趋势,而人均生态承载力略微呈下降趋势,故生态赤字逐渐增加。从横向对比分析,与昆明市与云南省相比,草海流域的生态足迹较高,而生态承载力较低,因而生态赤字远远高于昆明市及云南省平均水平,人均万元GDP生态足迹也较高。同时,基于生态足迹和生态承载力计算结果,可对草海流域生态适度人口进行估算并对其合理性进行分析。Calculation results of ecological footprint and ecological Caohai is 2. 728 hm^2 for per capita, the ecological carrying capacity up to 2. 670 hm^2 for per capita. From the dynamic changes of view, carrying capacity show that the ecological footprint in is for 0. 058 hm^2 for per capita. The ecological deficit is the ecological footprint for per capita rose gradually from 2000 to 2004, while the ecological carrying capacity for per capita went down slightly. It results ecological deficit increased gradually. Compared with the Kunming City and Yunnan Province, the ecological footprint of Caohai was higher, while the ecological carrying capacity was lower and thus the ecological deficit is much larger than that of Kunming and Yunnan Province. At the same time, based on the calculation results of ecological footprint and ecological carrying capacity, the ecological optimum population of Caohai can be estimated.
