生态足迹法在长沙县生态县建设中的应用

通过运用生态足迹计算方法,对长沙县2005年的生态足迹进行了计算,得出长沙县人均生态足迹是2.52hm^2/人,以及全县人均生态承载力为0.60 hm^2/人,从而可以看出全县人均生态赤字为1.92 hm^2/人,远远高于全国平均水平。全县生态赤字最多的是化石燃料土地,然后依次为耕地、水域、草地,这表明全县对自然环境的影响已经大大地超出了生态环境承载力,工业的飞速发展对化石燃料的消耗和耕地的占用的急剧增加是产生生态赤字的主要原因,同时人们生活水平的提高也对生态环境造成极大的压力。

THE APPLICATION OF ECOLOGICAL FOOTPRINT METHOD IN THE NSTRUCTION OF THE ECOLOGICAL COUNTY OF CHANGSHA COUNTY

Through the application of ecological footprint method in Changsha County in 2005, the per capita ecological footprint of Changsha County reached 2.52 ha per person , and the county per capita ecological carrying capacity of 0.60 ha per person. It can be seen that the county per capita ecological deficit of 1.92 ha per person, which is far higher than the national average. The largest county ecological deficit is land fossil fuels, to be followed by land, water, pasture, which shows that the county＇s impact on the natural environment has greatly exceeded the capacity of the ecological environment. The dramatic increase of fossil fuels consumed and land occupied by the rapid industrial development is the main reason of the ecological deficit, meanwhile, and the improvement of people＇s living level also caused a great deal of pressure on ecological environment.
