基于生态足迹模型的矿区可持续发展评估--以神木县为例

Evaluation of the sustainable development in mining area based on ecological footprint model:a case study of Shenmu County

运用生态足迹模型对陕西神木县2007年的生态足迹进行了计算和分析,分别以神木县总能源消费量(包括工业生产能源消费和非工业生产能源消费)和以非工业能源消费量计算了其生态足迹,前者生态赤字达17.058 ha/cap,后者生态盈余为0.209 ha/cap,说明神木县生态赤字主要来源于工业能源消费,即是通过高能耗产品将其他地区的生态足迹转移到了神木县。最后根据生态足迹分析结果,提出了关于神木县可持续发展的建议。

Ecological footprint model was used to analyze the ecological capacity and deficit/surplus of Shenmu County.The results show that the ecological deficit is 17.058 ha per capita when the total energy consumption（energy consumption coming from industrial and non-industrial production） is used to calculate the ecological footprints,whereas the ecological surplus is 0.209 ha per capita when the non-industrial energy consumption is used.The ecological deficit is mainly derived from the industrial energy consumption,and that energy is provided by Shenmu County but consumed outside of it.This means the ecological footprints of Shenmu County are shifted from the outside.Based on the analysis of ecological footprints,some measures for the sustainable development of Shenmu County were suggested.
