基于生态足迹模型的山西省生态评价

生态足迹是定量评价区域生态状况和可持续发展能力的重要模型.本文利用生态足迹模型对2011年的山西省生态足迹供需量进行计算与分析.结果显示2011年山西省的生态供需状况严重失衡,人均生态足迹需求量为5.677 7 hm2,而人均生态承载力仅为0.755 8 hm2;山西省该年处于不可持续发展状态,人均生态赤字高达4.921 9 hm2;全省的生态需求结构以能源消费需求量为重心,特别是煤炭资源;生态供给结构则以耕地为主,林地、建设用地次之.

Evaluating of the Ecological Regime Based on Ecological Footprint Model in Shanxi Province

Ecological footprint is an important model to quantitatively estimate a region＇s ecological regime and sustainable development ability. In this article we use ecological footprint model to calculate and analyse the ecological footprint of Shanxi Province in 2011. Result shows that ecological supply and demand of Shanxi Province is seriously unbalance in 2011. The per capita footprint is 5. 677 7 hm^2, while the per capita capacity is 0. 755 8 hm^2; Shanxi province is in unsustainable development at present, the per captia deficit is 4. 921 9 hm^2. The core of the ecological demand structure of Shanxi is energy demand, especially the coal consumption. The ecological supply structure is that the farmland is the main ,the forest land and constructive land is the secondary.
