摘要
利用生态足迹分析法方法计算了辽宁省及其沿海6市(葫芦岛、锦州、盘锦、营口、大连和丹东)2003—2005年的生态足迹,分析了生态足迹的变化规律及变化原因,并评价了该区域可持续发展状况。结果表明:2003—2005年辽宁省及其沿海6市的生态足迹均超过了其生态承载力,全省人均生态赤字有逐年增加的趋势;沿海6市中人均生态赤字最高的城市为盘锦市,然后依次为锦州市、葫芦岛市、营口市、丹东市和大连市。生态足迹供需结构表明,辽宁省及沿海生6市生态足迹需求主要以化石能源地为主,但均有较高的水域类生态盈余。3年间万元GDP生态足迹总体呈下降趋势,表明辽宁省及其沿海6市的资源利用率不断提高。最后提出了减少区域生态赤字的对策。
This paper calculated the 2003-2005 ecological footprints in Liaoning Province and its six coastal cities （Huludao, Jinzhou, Panjin, Yingkou, Dalian and Dandong）, analyzed the dynamic changes and their causes of the footprints, and evaluated the situation of the sustainable development in the study region. It was indicated that in 2003-2005, the ecological footprints in Liaoning Province and its six coastal cities exceeded the corresponding ecological capacity, and the per capita ecological deficit was increased annually. Of the six coastal cities, the per capita ecological deficit in Panjin was the highest, followed by Jinzhou, Huludao, Yingkou, Dandong, and Dalian. The land with fossil energy sources was the main demand of ecological footprint in the study region, while water area had a higher ecological surplus. The GDP per ten thousand yuan in 2003-2005 presented an overall downward trend, indicating that the resource use efficiency in Liaoning Province and its six coastal cities was improved gradually. The measures for reducing the ecological deficit were also proposed.
