辽宁省生态足迹动态变化分析

Analysis on Dynamic Changes of Ecological Footprint in Liaoning Province

生态足迹方法是定量测度区域发展可持续状态的一种简易方法。运用生态足迹计算模型测算了1998～2007年辽宁省的生态足迹和生态赤字。结果表明,辽宁省人均生态足迹总体上呈现逐年扩大的趋势,由1998年的3.024hm2/人上升到2007年的4.738hm2/人;人均生态承载能力呈现缓慢的下降趋势,下降速率为4.8%;生态赤字逐渐增大,由1998年的2.342hm2/人上升到2007年的4.088hm2/人,生态处于不可持续发展状态;万元GDP生态足迹整体呈下降趋势,从3.211hm2/万元下降到1.850hm2/万元,表明资源利用效率越来越高,经济发展能力逐步提高。

The theory of ecological footprint is an applicable method which measures the sustainable development level quantitatively.With this theory,the ecological footprint applying to Liaoning province from 1999 to 2007 has been researched.It shows that the ecological footprint per capita in Liaoning province,from 3.024 hm2/cap in 1998 to 4.738 hm2/cap in 2007,presents an expanding trend as a whole.Nevertheless the ecological capacity per capita is decreasing slowly at a rate of 4.8% and the ecological deficit per capita has been gradually increasing from 2.342 hm2/cap in 1998 to 4.088 hm2/cap in 2007,which shows that the ecology is in a state of unsustainable development;but the ecological footprint of ten thousand Yuan GDP is in a decreasing trend from 3.211 hm2/ten thousand to 1.850hm2/ten thousand,which demonstrates that the level of resources utilization and the economical development capacities have been enhanced gradually.
