采煤业生态足迹及地区间的差异

在计算江苏徐州市和山西长治市生态足迹的基础上，提出了计算采煤业生态足迹的方法.并用3种不同的方法比较了徐州和长治两地采煤业生态足迹的地区差异：徐州市开采万吨原煤的生态足迹占矿区生态承载力的比例为26%，长治市为51%；采煤业万元产值的生态足迹徐州市为0.74 hm²，长治市为0.78 hm²；按产值比重算，万吨原煤产量的生态足迹徐州市为52.07 hm²c长治市为66.81 hm².同时还分析了同一地区单位产值的采煤业与其他产业生态足迹的差异，长治市采煤业生态足迹与其他行业生态足迹较为接近，而徐州市采煤业生态足迹则远大于其他行业的生态足迹.

Ecological footprints in coal mining industry and inter-area differences

Based on ecological footprints model and the calculation of the ecological footprints of Xuzhou city in Jiangsu Province and Changzhi city in Shanxi Province in 2003,proposed the calculation method of ecological footprints of coal mining industry.Furthermore,by there different methods compared the inter-area differences of ecological footprints of coal mining industry: The ecological footprints of 104 tons coal mining accounted for 26% of ecological carrying capacity in Xuzhou city and for 51% in Changzhi city;The ecological footprints of 104 yuan production value of coal mining was 0.74 hm2 in Xuzhou city,while 0.78 hm2 in Changzhi city;According to production value proportion,the ecological footprints of 104 tons coal mining production was 52.07 hm2 in Xuzhou city,while 66.81 hm2 in Changzhi city.The difference of the ecological footprints demand per unit production value also was analyzed between coal mining industry and other industries in the same area.We found no significant in Changzhi city,while the ecological footprints demand of coal mining industry was much greater than other industries in Xuzhou city.
