基于灰色理论的矿业城市生态足迹演变研究

Evolvement of ecological footprint in mining city based grey theory

利用生态足迹分析方法对矿业城市生态足迹的变化情况进行分析,为矿业城市可持续发展提供重要理论依据。研究结果表明焦作市为了调整产业结构,促进经济转型,加快工业发展和城市化进程,人均生态足迹正在逐年上涨。利用灰色理论分析了生态足迹和社会发展指标体系之间的定量关系,最后预计到2010年,焦作市的人均生态足迹为4.2208 gha,生态容量为0.3535 gha,生态赤字进一步加大。

Mining city plays an important role in China. however, with the reform of system of economy and mining resource decreasing, many problems appear in mining city, which affect the sustainable development. The change of ecological footprint in typical mining city is studied in this paper to provide theoretical base for economical reconstruct. The studied result indicates that the ecological footprint of per capita and ecological footprint deficit is increasing year after year in Jiaozuo City due to industrial structure adjustment. The total ecological footprint has a little wave. Then the relationship between ecological footprints is analyzed based on grey theory. Finally, based on the data of economical development plan, the ecological footprint in year 2010 is predicated to be 4.2208gha and ecological capacity to be 0.3535gha, ecological footprint deficit will increase.
