摘 要: 运用生态足迹分析法,对开封市1999~2007年的生态足迹变化进行了动态分析。结果表明,在1999~2007年,开封市人均生态足迹需求呈现整体上升趋势,由1999年的1.54hm2/人上升到2007年的1.94hm2/人;人均生态承载力变化幅度不大,为0.33~0.38hm2/人;万元GDP生态足迹呈明显下降趋势,从3.58hm2/万元GDP降低到1.76hm2/万元GDP;除2003年外,生态赤字表现出明显的加重趋势,由1999年的-1.20hm2/人变为2007年的-1.57hm2/人,这表明开封市的自然资源目前仍处于过度开发的状态。 Using the ecological footprint analysis method,the ecological footprint change dynamics of Kaifeng during 1999-2007 was analyzed.The results showed that per capita ecological footprint demand of Kaifeng City rose from 1.54 hm2 per capita in 1999 to 1.94 hm2 per capita in 2007,showing a whole increase trend during 1999-2007.The carrying capacity per capita had little change range of 0.33-0.38 hm2 per capita.The ecological footprint per 10 000 RMB of GDP dropped from 3.58 hm2 to 1.76 hm2,showing an obvious decrease trend.Except 2003,the per capita ecological deficit changed from-1.20 hm2 in 1999 to-1.57 hm2 in 2007 with the obvious aggravating trend,which indicated that the natural resources of Kaifeng was overdeveloped.
