摘    要:可持续发展的定量测度研究是当前国际上关于生态经济研究的前沿问题之一。生态足迹分析法是近年来发展的用于定量研究和判断一个国家或地区的可持续发展状况的新方法。应用生态足迹的方法 ,以辽宁省 2 0 0 0年 ,2 0 0 1年 ,2 0 0 2年统计资料为依据 ,对其 1999~ 2 0 0 1年 3a的生态足迹进行了实证计算和研究 ,从纵向比较并分析了辽宁省生态足迹的变化规律及其原因。研究结果表明 :辽宁省生态赤字呈逐年增加的趋势 ,1999年人均生态赤字为 2 .2 90 hm2 ,2 0 0 0年为 2 .36 8hm2 ,2 0 0 1年为 2 .4 74hm2 ,其主要影响因素是由于资源过度消耗 ,人口增长以及耕地减少等。通过生态足迹的研究 ,提出了辽宁省在振兴东北老工业基地 ,进行可持续发展过程中应采取的对策措施

关 键 词:生态足迹  可持续定量测度  生态承载力  辽宁省

Abstract:Measuring sustainable development is one of the frontiers of ecological economics. The present study aims to determine whether the ecological carrying capacity of nature can satisfy human beings' needs by quantitative indicators. Ecological Footprint Analysis is a new method for measuring ecologically sustainable development. The method is used to calculate ecological footprints from the facet of need and the ecological carrying capacity from the facet of support. From its results, we can judge the sustainable development situation a country or an area is in. This paper introduces the concept of ecological footprints and a calculation method, and calculates the ecological footprints from 1999 to 2001 in Liaoning Province, and analyzes the laws and causes of the vertical changes in its ecological footprints. Liaoning is a heavy-industry province in north-east in China, it was famous for its machine-building industry in past years. Now, it is facing some problems in the process of development. This paper aims to find out what the primary problem is and what causes it, by way of ecological footprints.Research results show that the ecological deficit of Liaoning Province has gradually increased over the years, and from 2.290 to 2.474 hm~2per capita from 1999 to 2001. The ecological footprint per capita over these years in Liaoning is 2.870hm~2, 2.945hm~2 and 3.049hm~2, and its ecological carrying capacity per capita is 0.580hm~2,0.577hm~2 and 0.575hm~2 respectively. The ecological deficit in 2001 jumped 3.4% above that of the previous year, and in 2002 it jumped 4.5% above 2001. Through analysis of the factors influencing the ecological footprint of Liaoning from 1999 to 2001, it was found that among all the factors, the rates of consumption of fossil energy are all over 50%, creating the primary factor.Apart from the main causes of over-consumption of fossil-energy, it was also found that arable land, forest and pasture land had become reduced and built-up areas increased which is the other main cause for the ecological deficit in Liaoning. This paper also provides some measures for solving the problem in Liaoning Province, and a model for sustainable development and economic promotion is proposed from the research results.
Keywords:ecological footprints  measuring sustainable development  ecological carrying capacity  Liaoning Province
