摘要 生态足迹分析方法是一种定量研究可持续发展的新方法。该方法能够定量衡量人类对自然利用程度。计算和分析了辽宁省2002年生态足迹和生态承载力,并且在时间维上对近18年化石燃料用地和建筑用地足迹需求进行了动态分析。结果表明,2002年辽宁省人均生态足迹2.426hm2/人,人均生态承载力0.878hm2/人,生态足迹需求是该地区生态承载力的2.8倍。当前辽宁省发展处于一种不可持续状态,出现生态赤字1.548hm2/人。近18年化石燃料用地和建筑用地足迹需求基本呈线性增长趋势。针对辽宁省具体情况提出了减少生态赤字,实现可持续发展的途径。辽宁作为中国的老工业基地,当务之急是改善能源结构,提高能源效率,逐步降低煤炭在一次能源消费中的比重,实现该区域的可持续发展。 The analysis of EF(ecological footprint) is a new method of quantitative study of sustainable development, which can quantify human impact on natural ecosystem. It focuses on calculating and analyzing the ecological footprint and the ecological carrying capacity of Liaoning Province in the year 2002 and concludes that the ecological footprint is 2.8 times of the locally ecological carrying capacity. It indicates that Liaoning's ecological footprint, ecological carrying capacity and ecological deficit are 2.426 hm^2/cap , 0.878 hm^2/cap and 1.548 hm^2/cap, respectively. Also the fossil-energy's and build-up area's EF (1985~2002) are summarized in this paper, and the research results show that the fossil-energy's footprint and build-up's footprint increased in the way of linearity. As an outmoded industrial base, it is urgent for Liaoning Province to improve and optimize the energy structure, to use energy efficiently, and to reduce the share of coal consumption in the primary energy consumption gradually.
