沈阳市可持续发展的生态资源占用核算与分析

利用生态足迹方法对沈阳市1993~2004年的生态资源占用进行计算,结果表明,沈阳市1993~2004年人均生态资源占用平均为2.1075 hm2,人均生态承载面积平均为0.724 8hm2,人均生态赤字平均为1.3827 hm2.人均生态资源占用是人均生态承载面积的3倍.1993~2004年间,以人民币表示的生态消耗强度从1993年的3.123 hm2/万元降低到2004年的0.839 hm2/万元,生态效率从3 202元/hm2提高到了11919元/hm2,生态效率提高了2.72倍,年平均增长率为22.69%.生态效率的上升说明单位产出对资源的占用逐渐降低,进一步说明了沈阳市在这12年来对...

Sustainability Analysis of Shenyang City by Checking the Occupancy of Ecological Resources

Ecological footprint(EF) was used to measure the occupancy of ecological resources in Shenyang City's economic development from 1993 to 2004.The results showed that in the 12-year period the per capita resource occupancy,bearing area and deficit were 2.107 5 hm2,0.724 8 hm2 and 1.382 7 hm2,respectively,i.e.,the per capita resource occupancy is about 3 times as large as the per capita ecological deficit.Calculated with the unit in 1 000 RMB yuan,the intensity of resource use(IRU) decreased from 31.23 hm2 in ...
