| 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。

| Abstract: | 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 hm~2 per capita in 1999 to 1.94 hm~2 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 hm~2 per capita. The ecological footprint per 10 000 RMB of GDP dropped from 3.58 hm~2 to 1.76 hm~2, showing an obvious decrease trend. Except 2003, the per capita ecological deficit changed from -1.20 hm~2 in 1999 to -1.57 hm~2 in 2007 with the obvious aggravating trend, which indicated that the natural resources of Kaifeng was overdeveloped. |
