摘　　要：运用生态足迹方法对新乡市1997-2005年的生态足迹需求与承载力进行了计算,结果表明,该市人均生态需求保持在1.6 hm2左右,而人均生态承载力在0.54 hm2左右徘徊且呈下降趋势,生态赤字达到了1.0 hm2;表明其生态足迹需求远超出了生态承载力范围,城市发展在国家尺度上处于不可持续状态.The ecological footprint method was used to calculate the ecological footprint demand and ecological carrying capacity of the Xinxiang city from 1997 to 2005. The result showed that the ecological footprint demand per capita of Xinxiang city in these year kept around 1.6 hm^2; while the capacity, around 0.54 hm^2 with an decline tendency. The ecological deficit is 1.0 hm^2, which means that the ecological footprint demand has already overtook the ecological carrying capacity. It isn＇t sustainable according to the national standard. The result could supply a base for the city strategy planning and industrial structure adjusts.
