甘肃省2006年生态足迹计算及分析

运用生态足迹模型对甘肃省2006年的生态足迹进行了计算和分析.结果表明,2006年甘肃省人均生态足迹供给小于人均生态足迹需求,人均生态赤字为0.85 hm2.生态协调性系数指标分析显示,甘肃省的发展是通过消耗自然资本存量来弥补生态承载力不足,处于一种生态不协调状态.对16 a生态足迹分析发现,甘肃省于1998年开始出现生态赤字,且呈逐年加剧的状况,2006年达0.85,表明甘肃省区域生态经济系统生态承载力已超过阈值,生态状况极其脆弱,仍然处于区域不可持续的发展状态.

The calculation and analysis of ecological footprint of Gansu Province in 2006

The ecological footprint model was applied to calculate and analyze the ecological footprint of Gansu Province in 2006.The result showed the supply per capita of ecological footprint was less than it′s demand,the ecological deficit per capita was 0.85 hm2.The result was analyzed by the index of ecological coordination coefficient,which showed the development of Gansu Province was in a state of ecological incoordination,natural stock was made up for a shortage of ecological capacity.Compared with ecological footprints of the province in past sixteen years,we found the supply of ecological footprint had been a change in the opposite direction comparing with it′s demand since 1998,ecological deficit was increasing year after year,it was 0.85 in 2006.The results also indicated that the regional ecological and economic system of Gansu Province went beyond threshold of ecological capacity,it′s fragile ecological conditions wasn′t fundamentally improved,Gansu Province was still in a regional unsustainable development situation.
