摘要
生态足迹分析法现已广泛应用于各种可持续发展的测度,文章应用该方法对甘肃省的可持续发展状况进行了评价和分析.在1996-2003年间,每隔一年计算出甘肃省的生态足迹,以此来对甘肃省可持续发展状况的动态变化进行测度和分析.计算结果表明,人均需求足迹整体为上升趋势,人均供给足迹整体为下降趋势;生态冗余只有1996年为正,即处于可持续发展状态;其余4个年份均为负值,即为不可持续发展状态.在历年人均生态足迹需求的各组成土地类型中,化石燃料用地和耕地是主要的两个组成类型,其次是草地;在人均生态足迹供给的组成中,耕地和草地是最主要的两个组成类型.
Ecological footprint has been widely used for sustainable development measurement. This paper,with the ecological footprint method,makes a time sequence calculation of the ecological footprints of Gansu Province from 1996 to 2003,incorporates the dynamic characteristics of the Province＇s resources utilization into ecological footprint model, and, based on these, analyzes the development trends of this Province. It shows that the per capita demand of ecological footprint presentes increase trend, while the per capita supply of ecological footprint downwards trend;Gansu Province is in a sustainable status in 1996 and in a unsustainable status in other remaining four years,suggesting that the development status of Gansu Province from 1996 to 2003 was not optimistic.
