摘要
矿业城市的生态环境极其脆弱,其可持续发展程度为社会广泛关注。本文在生态足迹评价模型的基础上,对矿业城市武安市2005年的生态足迹结构和生态承载力结构进行了分析,并结合其他5个矿业城市进行生态足迹比较、区域资源利用效益分析和可持续发展测度3个方面的研究。研究结果显示,矿业城市的人均生态足迹远大于人均生态承载力,均出现生态预警,处于恶性发展状态。造成生态赤字的主要原因是由于矿业城市的能源消耗需求量大。本文针对矿业城市的资源特殊性,提出矿业城市持续发展的建议。
The environment in mining cities is frail, whose sustainable development catches much attention from public. This paper, based on an evaluation of ecological footprint models, analyzes the ecological footprint structure and loading structure in mining city Wu＇ an in 2005, compares among five other mining cities in regional resources utilization and sustainable development. The results indicate that the per capital ecological footprint is much bigger than per capital loading in mining cities, implying a deteriorating development. The ecological deficit is derived from big energy consumption in mining cities. This paper presents some suggestions for the sustainable development in mining cities.
