摘要
以石家庄市为例,运用生态足迹模型,对1996—2006年间的生态足迹、生态承载力、生态赤字等进行了测算与纵向对比分析,并与国内外其他地区进行横向对比分析。结果表明,石家庄市人均生态承载力由1996年的0.3616hm2/人下降到2006年的0.3227hm2/人,而同期的人均生态足迹从2.4893hm2/人增加到4.690hm2/人,生态足迹和生态赤字水平远超过国内大部分地区的平均水平,呈逐年递增的趋势,反映出石家庄市的土地生态系统安全性不高。
This paper based on the Shijiazhuang City as an example,used the method of ecological footprint to evaluate the land carrying capacity of Shijiazhuang City.Using the method of ecological footprint calculated the ecological footprint,ecological carrying capacity and ecological deficit of Shijiazhuang during 1996 to 2006.Besides,did the comparison with other areas at home and abroad.The results showed that the ecological carrying capacity of Shijiazhuang decreased from 0.3616hm2/cap to 0.3227hm2/cap in 11 years while the ecological footprint increased 2.4893 hm2/cap to 4.690 hm2/cap.Compared with other areas,the ecological footprint and ecological deficit far exceeded the national average in most areas.The ecological footprint and ecological deficit increased continually,reflecting the Shijiazhuang City land ecosystem safety was not high.
