矿业城市生态承载力与可持续发展研究——以河北省武安市为例

Study on Ecological Carrying Capacity and Sustainable Development in Wuan,Hebei

矿业城市生态足迹的变化是其经济发展对生态环境影响的综合反映。文章采用生态足迹评价模型对矿业城市武安2007年的生态足迹进行计算和分析。结果表明:武安市的生态足迹远远大于生态承载力、资源利用效率不高、生态足迹多样性水平较低、武安市处于严重的生态赤字状态,而造成生态赤字的主要原因是由于武安市的能源消耗量大。武安市应转变经济增长方式,提高资源利用率,加大生态环境建设的投入,发展循环经济,提高生态承载力,进而促进武安市的可持续发展。

Sustainable development situation of a mining city reflects the coordination of its industrial structure and environment-friendly society. This paper uses ecological footprint assessment model to calculate and analyze the ecological footprint of Wuan. The results show that the ecological footprint of Wuan is far greater than its ecological capacity, and the efficiency of resource utilization and the diversity of ecological footprint are fairly low. As a result, Wuan is in the serious situation of ecological deficit. The main reason for the ecological deficit is the great demand of energy consumption. In order to promote the sustainable development, Wuan should both change the mode of economic growth and improve the efficiency of resources utilization. In addition, it is also necessary to increase the input of the ecological environment constmction, to develop circular economy and to improve the ecological capacity.
