吴江东部地区可持续发展的生态足迹分析

可持续发展定量测度的核心内容是确定人类社会经济发展对资源与生态环境胁迫程度是否处于生态系统的承载力范围之内。采用目前国内外广泛使用的生态足迹方法,对吴江东部地区2000~2003年的可持续发展状况进行了定量测度,并进行了生态足迹的多样性和发展能力的测算。结果表明,吴江东部地区人均生态足迹与人均生态赤字逐年提高,说明社会经济发展处于不可持续状态;单位生态足迹产值逐年提高,说明资源的总体利用效率不断提高;生态足迹的多样性和发展能力指数不断提高,说明各类用地的比例有趋于平衡的趋势。

Ecosystem Footprint Analysis of the Sustainable Development in the East of Wujiang

In this paper,the status of sustainable development in the east of Wujiang in 2000～2003 was measured quantitatively with the method of ecological footprint,and the diversity of ecological footprint and development ability were measured.The results showed that:Ecological footprint per capita and ecological deficit per capita were increased year after year,while ecosystem capacity was decreased year of year,which showed society and economy lied in the state of unsustainable development;The production value per ecological footprint was increased year after year,which showed the using efficiency of resources improved;The diversity of ecological footprint and development ability was increased,which indicated any kind of land-using had the trend of balance.
