摘要:

以辽中地区矿业城市(鞍山、抚顺、本溪)为例,基于能值理论并加入社会经济系统发展指数对生态足迹模型进行修正研究.结果表明,运用生态足迹修正模型计算,辽中地区矿业城市人均生态承载力为1.72hm2,人均生态足迹为6.95hm2,人均生态赤字5.23hm2,处于严重超载状态;生态足迹构成中能源足迹比例最大,达到55%.经过验证,生态足迹修正模型计算结果更加全面、合理.

关键词: 生态承载力, 能值分析, 社会经济系统发展指数, 生态足迹修正模型, 辽中地区矿业城市

Abstract:

In order to improve the veracity of the ecological footprint model, the emergy analysis and social-economy system development index were introduced into the model, and the mining cities in central Liaoning were taken as cases. Results showed that, based on the modified model of ecological footprint, the EF was 6.95hm2, the EC was 1.72hm2, and the per capita ecological deficit was 5.23hm2 in 2005, so the overloading degree of EF of mining cities in central Liaoning was serious. The proportion of energy ecological footprint was the highest (55%). The test results indicated that, the analysis of the modified model could be more exact.

Key words: ecological carrying capacity, emergy analysis, social-economy system development index, modified model of ecological footprint, mining cities in central Liaoning
