基于生态足迹的河南省生态承载力评价

目的]为了分析河南省2000年-2010年近10年来生态承载力,方法]应用生态足迹法,采用2000年、2005年、2010年三个时间段的数据,分析了河南省人均生态足迹、人均生态供给、人均生态赤字和生态承载力指数的变化。结果]结果表明：(1)河南省的人均生态足迹由2000年的0.8288hm2至2005年急增为2.0368hm2,至2010年下降为1.8739hm2；(2)从2000年至2010年河南省人均生态供给由0.3994hm2降低为0.3667hm2,人均生态赤字由2000年的0.37hm2至2005年急增为1.61hm2,至2010年下降为1.46hm2；(3)生态承载力指数均大于1,处于超载状态。结论]因此随着经济增长方式的转变,河南省生态超载状况有所缓解。

Evaluation of Ecological Bearing Capacity in Henan ProvinceBased on Ecological Footprint

In order to analyze the changes of ecological bearing capacity in the years of 2000-2010 in Henan province, This paper applied the ecological footprint method, using the data of three periods,2000,2005 and 2010, analyzed per capita ecological footprint, ecological supply and per capita ecological deficit and per capita ecological carrying capacity index .The results show that: (1) the per capita ecological footprint in Henan Province increased sharply from 0.8288 hm2 in 2000 to 2.0368 hm2 in 2005, while declined to 1.8739 hm2 by 2010; (2) the per capita ecological supply between 2000 and 2010 reduced year by year ,which dropped from 0.3994 hm2 to 0.3667 hm2,And the per capita ecological deficit added drasticly from 0.37 hm2 in 2000 to 1.61 hm2 in 2005 while decreased to 1.46 hm2 by 2010;(3) ecological bearing capacity index are all greater than 1, which are in a state of overload. As the change of economic growth mode, the situation eased somewhat although it is still in a state of overload.
