基于改进生态足迹模型的中国31个省级区域生态承载力实证研究

发达地区通过向欠发达地区转移污染型行业,导致污染由发达地区向欠发达地区转移。同样,在资源的开发利用过程中,生态破坏在区域之间也存在着明显的间接转移。一个地区使用了大量的生态资源,但其绝大部分资源都可能是靠输入,在这种情况下,输入资源地区的生态系统受到了很好的保护,而输出资源地区的生态系统却承受了巨大的生态压力。通过实证研究,应用改进生态足迹模型分析比较了2008年中国31个省市区生态承载力,并讨论了区域间生态破坏转移问题,为实现以生态文明为核心价值取向的区域协调发展战略目标提供决策参考。

Ecological Carrying Capacity of 31 Provinces Based on Improved Ecological Footprint Model

During the process of regional industrial transfer and industrial restructuring, the evolution of regional industrial structure sharply contradicts with decreasing of resources and lowing of environmental carrying capacity because of lacking industrial economic and ecological efficiency from the overall view. The pollution was transferred from the developed regions to the developing regions caused by the transfer of polluting industries. Similarly, in the process of development and utilization of resources, conspicuous transfer of ecological destruction exists among regions. A province uses a large number of ecological resources, but most of which are likely to rely on imports, in this case, the ecological system of this province has been protected, but the ecological system of provinces which export the resources are under great ecological stress. Through the empirical studies, this paper analyzed and compared the ecological carrying capacity of 31 provinces of China in 2008, based on the improved ecological footprint model, and discussed the problem of transfer of ecological destruction between regions. The empirical analysis shows that the ecological damage transferred clearly among the regions, the ecological system in the eastern region of China has been well protected, while the pressure of ecological system is increasing in the central and western areas of China where export resources. Therefore, the economic development mode for various areas should be further changed, and the the regional policy made by central government should be further improved.
