生态足迹法在可持续发展度量及趋势预测中的应用

The Application of Ecological Footprint to the Measurement of Sustainable Development And Trend Forecast

生态足迹法是一种定量度量可持续发展的有效方法。在介绍该理论方法的基础上,针对吉林省西部大安市发展现状和存在的严重生态环境问题,运用RS—GIS集成技术,借助ERDAS,ARCGIS等专业软件提取了研究区土地利用的动态数据,结合静态数据资料,对大安市生态环境的可持续发展状况进行了量化研究。结果表明,2001年大安市的生态需求大于生态供给,生态呈现“供不应求”的局面,人均生态赤字为0.56hm2,处于弱不可持续发展状态。通过预测,到2010年,大安市的人均生态赤字为1.222hm2,处于不可持续发展状态。

Ecological footprint is an effective method for quantitatively measuring sustainable development in quantity. Based on the ecological footprint theory, an integrated technology of RS--GIS was used, and the dynamic data on the land use ,extracted by ERDAS and ARCGIS , were combined with the static data to realize the quantified research of sustainable development of Da＇an . The results showed that the ecological demand was larger than ecological supply and the city was in the weakly unsustainable state with ecological deficit of 0.56 hectares per capita in 2001. A forecast reveals that the city will be in the state of unsustainable development with ecological deficit of 1. 222 hectares per capita in 2010.
