摘要
利用生态足迹分析方法的模型,对宁夏1980、1985、1990、1995、1998-2005年的生态足迹和生态承载力进行计算。结果表明在1980-2005年间,除1990-1995年宁夏人均生态足迹有所降低以外,其余期间均处于增长趋势;宁夏人均生态足迹由1980年的0.61 hm^2增加到了2005年的2.39 hm^2,草地、化石能源和耕地是生态足迹的主要供给部分。人均生态承载力由1980年的1.22 hm^2降低到2005年的0.76 hm^2,生态承载力一直处于降低趋势,耕地和草地是生态承载力的主要供给部分。1995年是宁夏生态经济系统可持续发展状态的转折点,此前宁夏的生态承载力大于生态足迹,此后生态承载力开始小于生态足迹并出现生态赤字,即现在的经济发展处于不可持续发展状态。
Ecological footprint analysis is a new method for measuring regional economic sustainable development. The ecological footprint and ecological capacity of Ningxia Hui Autonomous Region in 1980, 1985, 1990,1995 and 1998-2005 are calculated using this method. The results show that the ecological footprint per capita increased from 0.61 hm^2 to 2.39 hm^2 except the period of 1990- 1995 in which it reduced. The pasture, fossil energy land and arable land are the main parts of ecological footprint. The ecological capacity per. capita is reduced year by year from 1.22 hm^2 to 0.76 hm^2. The arable land and pasture are the main parts of ecological capacity. Before 1995, the ecological capacity was higher than the ecological footprint and the economic develop- ment was sustainable. But, the ecological deficit arose in 1995. The results show that the economic developing model of Ningxia is not sustainable after 1995.
