近年来生态足迹研究进展

本研究对国内外生态足迹的理论假设、计算方法、贸易赤字、生态超载和基于生态足迹分析的可持续发展静态和动态评估进行了简要介绍,详细讨论了生态足迹的理论假设、计算方法等;回顾了近年来国内外的进展,其研究应用范围从省级行政区进一步扩展到乡镇级行政区和能源、旅游、种养殖业、交通、贸易、大学等产业领域的研究,动态研究也大量增加;对生态足迹理论和应用研究在流动人口、地区生态足迹分析的理论假设、基于生态足迹分析的可持续状况横向比较、各类土地互斥假设、生态足迹分析理论在用于城市型国家或城市等人口高密集地区或不发达地区的可持续性测度时的限制等方面存在问题,提出了相应的改进意见和建议。文章的最后指出了国内围绕生态足迹研究应尽快开展的工作:积极开展生态足迹理论和方法的改进与完善研究、开展上年结转和本年结余资源对生态足迹计算的影响研究、开展国家公顷和省公顷等地方公顷研究,以及积极开展水产养殖渔业、圈养牧业均衡因子研究等。

Advances in ecological footprint

As a biophysical method used to compare the utility degree of natural resource with the life-supporting service function,ecological footprint,since it brought forward,has been a useful and powerful indicator of measuring the regional developmental sustainability.It has been applied in different fields: regions,tourism,resource,fish farm,paddy field,greenhouse gas emissions,transportation,etc.This paper firstly introduces concisely the assumption,ecological trade deficit,ecological overshoot of ecological footprint,and measures the regional development sustainability based on ecological footprint analysis.Particularly,this paper has discussed its assumptions,methods;and has reviewed in details the latest achievement and frontiers of ecological footprint.This paper put forward the improving suggestion for the floating population affecting, assumptions of sub-nation and other problems of ecological footprint.According to the above,the further research work as the paper concluded the following theory,methods,influence of resources of carry forward/balance,study in national hectare or provincial hectare,equivalence factors of aquiculture,aquaculture and stock farming in shed.
