资源型城市生态足迹分析

Analysis of ecological footprints of resources-based city

生态足迹方法作为一种度量可持续发展程度的生物物理评价方法,被广泛应用于全球、国家、地区、城市、旅游业甚至家庭消费等各个层面。文中以资源型城市河南省鹤壁市为例,从生物资源账户、能源账户和资源输出账户三部分构建生态足迹框架,突出强调资源开采对城市可持续发展的影响。计算结果表明,2002年鹤壁市生态足迹6.9279hm2/人,生态承载力0.3781hm2/人,生态赤字达6.5498hm2/人,远远超过中国平均生态赤字1.2469hm2/人,说明鹤壁市处于一种不可持续的发展状态。

The ecological footprint method is a biophysical assessment method of the human appropriation of ecological capacity,and applied global, country, region, city, tour and family consume. The paper, By taking resources-based city-Hebi City as an example, design the structure of the ecology prints, including the biologic resource account, energy sources account and resource output account, It emphasize the influence that exploitation of resources act on the sustainable development of city. The result showed that ecological footprint （EF） of Hebi city is 6.927 9 hm^2.cap^-1 in 2002, bio-capacity （BC） is 0.3781 hm^2.cap^-1 in 2002, andthe ecological deficit （ED） （6.549 8 hm^2·cap^-1 in 2002） was also higher than the average level （1 .246 9 hm^2.cap^-1） in China. So the analysis indicated that Hebi city was not in sustainable development status.
