生态占用模型是可持续发展定量评价中的一种直观而有效的方法。甘肃省经济比较落后,支柱产业对自然资源的依赖性强,属于资源输出型地区。从消费的角度计算甘肃省的生态占用,难以准确反映其资源利用程度。本文利用生态占用的理论和方法,从生产的角度对甘肃省2005年的生态占用进行计算,并与其生态容量进行比较。结果表明,2005年甘肃省的人均生态占用为2.24hm2,而人均生态容量为1.13hm2,人均生态赤字高达1.11hm2,超载98.58%。这说明甘肃省对自然资源的开发利用程度已大大超过其生态承载力,其发展是不可持续的。
Ecological footprint model is an intuitive and effective method for quantitative evaluation of sustainable development. Gansu Province, the economy is relatively backward, the pillar industries rely on natural resources and strong, belong to the resource-export areas. Calculating the ecological footprint of Gansu Province from the perspective of consumption makes it difficult to accurately reflect the degree of resource utilization. In this paper, the ecological occupancy of the theory and method of production from the perspective of Gansu Province in 2005 to calculate the ecological footprint, and its ecological capacity to be compared. The results showed that in 2005, the per capita ecological footprint of Gansu Province was 2.24hm2, while the per capita ecological capacity was 1.13hm2. The per capita ecological deficit was as high as 1.11hm2 with an overload of 98.58%. This shows that the development and utilization of natural resources in Gansu Province has greatly exceeded its ecological carrying capacity, and its development is unsustainable.
