基于生态足迹理论的凤阳县矿产资源规划生态承载力分析

Application of Ecological Footprint to the Mineral Resources Planning Environmental Impact Assessment——A case study ofmineral resources planning of ecological capacity of Fengyang County

采用可变世界单产法计算了2007～2011年凤阳县的生态足迹,得出人均生态盈余由2007年的1.412hm2下降到2011年的1.263hm2,说明了近年来凤阳县人口对自然资源的消费量逐年增加,生态足迹与生态承载力之间的矛盾加剧。根据凤阳县矿产资源总体规划实施内容,规划末期2015年人均生态足迹为0.960hm2/人,生态承载力为2.013hm2/人,生态盈余为1.053hm2/人,评价区域仍有一定的生态承载力,说明规划区在规划的指导下有序、合理的开发,生态承载力能满足凤阳县矿产资源规划方案的实施。

Ecological footprint is an important indicator to analyze the sustainable use of natural resources . This article calculates the ecological footprint of Fengyang County from 2007 to 2011 by adopting variable world yield method .The results show that the ecological surplus per capita has decreased from 1 .412 hm2 of2007 to 1 .263 hm2 of2011 ,w hich is highly possibly resulted from gradually increased natural resource de-velopment in the past few years .It shows the conflicts between ecological footprint and ecological capacity are going up .According to mineral resource development plan of Fengyang County ,in the year of 2015 , theecological footprint per capitawill reach0 .960 hm2 ,the ecological capacity per capitawill reach2 .013 hm2 and ecological surplus per capita willreach1 .053 hm2 .It indicates that the ecological capacity can fulfill the implementation of mineral resource development plan of Fengyang County if the development is under scien-tific and reasonable indication .
