绥化市可持续发展状况的生态足迹分析

可持续发展定量测度的核心内容是确定人类是否生存于生态系统的承载力范围之内。本文应用Wackernagel等提出的生态足迹概念和方法对绥化市的生态足迹进行了计算和分析,并进行了生态足迹的多样性和发展能力的测算。绥化市2001年人均生态赤字为0.42 hm²,较1998和1999年赤字的幅度有所下降,同时通过万元GDP的生态足迹分析表明,其资源的利用效益在不断提高。建议通过增加生态足迹的多样性提高资源的利用效益,降低生态足迹,使绥化市进入可持续发展的模式。

Ecological Footprint of Sustainable Development of Suihua City

The main content of estimation of sustainable development is to ensure human load stay within global carrying capacity. Because humans consume the products and services of nature, every one of us has an impact on the earth.The ecological footprint concept has been designed to answer this question and estimate man's inpact on nature. The ecological footprint of any defined population(from a single individual to a whole city or country)is the total area of ecologically productive land and water occupied exclusively to produce all the resources consumed and to assimilate all the wastes generated by population.The ecological footprint method presents a simple framework for national natural capital accounting. In the paper,we introduced the concept of ecological footprint and its calculation method.And the article calculates and analyses the ecological footprint of Suihua City over recent 10 years. And, we surveyed diversity of ecological footprint and development ability. The ecological footprint ledger is composed of two main sections. The first ledger is basic biotic resources comsumption including its byproducts,the second is energy comsumption.Based on the ecological footprint concept and analysis framework,human consumption can be compared with regional-level natural capital production using existing data.The results showed that the ecological footprints deficit of Suihua City was 0.421ha per capita in 2001 which is declined by 1998 and 1999. And results demonstrated that utilization benefit of resource increased.The method of improving sustainable development of Suihua City is increasing ecological footprint's diversity and reducing footprints.
