摘要
为了分析河南省2000—2010年近10年来生态承载力,笔者应用生态足迹法,采用2000、2005、2010年3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。结果表明:(1)河南省的人均生态足迹由2000年的0.8288 hm2急增至2005年的2.0368 hm2,至2010年下降为1.8739 hm2;(2)从2000年至2010年河南省人均生态供给由0.3994 hm2降低为0.3667 hm2,人均生态赤字由2000年的0.37 hm2急增至2005年的1.61 hm2,至2010年下降为1.46 hm2;(3)生态承载力指数均大于1,处于超载状态。可得出结论,随着经济增长方式的转变,河南省生态超载状况有所缓解。
In order to analyze the changes of ecological bearing capacity in the years of 2000—2010 in HenanProvince, the author applied the ecological footprint method, used the data of three periods, 2000, 2005 and2010, analyzed the change of per capita ecological footprint, ecological supply and per capita ecological deficitand per capita ecological carrying capacity index. The results showed that：（1） the per capita ecologicalfootprint in Henan Province increased sharply from 0.8288 hm^2 in 2000 to 2.0368 hm^2 in 2005, while declinedto 1.8739 hm^2 by 2010;（2） the per capita ecological supply between 2000 and 2010 reduced year by year,which dropped from 0.3994 hm^2 to 0.3667 hm^2, and the per capita ecological deficit increased sharply from0.37 hm^2 in 2000 to 1.61 hm^2 in 2005 while decreased to 1.46 hm^2 by 2010;（3） ecological bearing capacityindex was greater than 1, which was in a state of overload. As the change of economic growth mode, thesituation eased somewhat although it is still in a state of overload.
