摘要
利用投入产出法对青海省2002～2007年的生态足迹进行测算。结果表明:青海省人均生态足迹由2002年的1.914 8 hm2减少到2007年的1.080 4 hm2,降低了43.58%;2002年,人均生态足迹贸易盈余0.128 52 hm2,2007年变化为微量贸易赤字,值为-0.006 17hm2。青海省应该进一步优化产业结构,促进生态足迹贸易,减少贸易赤字。
The ecological footprint of Qinghai Province during 2002-2007 was measured with the input-output model.The results showed that the per capita ecological footprint of Qinghai Province has decreased by 43.58% from the 1.914 8 hm2 in 2002 to 1.080 4 hm2 in 2007;the per capita ecological footprint of the trade surplus was 0.128 52 hm2 in 2002,but it changed into micro-trade deficit in 2007,a value of-0.006 17 hm2.As a suggestion,Qinghai Province should further optimize its industrial structure,promote the ecological footprint of trade,and reduce trade deficit.
