摘　　要：利用水资源生态足迹分析方法对安阳市2005~2014年的水资源生态足迹、生态承栽力进行了计算分析。结果表明,2005~2014年安阳市人均水资源生态足迹均值为0.45 hm^2/cap,且呈波动下降趋势。其中生产用水生态足迹占水资源生态足迹比重最大,达82.8%~91.4%,生活用水足迹其次,生态用水足迹最小,但呈上升趋势。安阳市水资源人均生态承载力较小,在0.048 hm^2/cap^0.068 hm^2/cap之间,受气候、水文起伏波动较大。安阳市2005—2014年间,水资源生态足迹均处于赤字状态,说明安阳市水资源利用长期以来一直是不可持续的。近10年来,安阳市万元GDP水资源生态足迹整体呈较快下降趋势,表明安阳市水资源利用效率正逐步提高。By using the ecological footprint analysis method, the ecological footprint andecological carrying capacity of water resources in Anyang from 2005 to 2014 were analyzed and calculated.The results show that the average value is 0.45 hm^2 / cap of the ecological footprint of water resources from 2005 to 2014 in Anyang urban, and the trend is decreasing. The ecological footprint of water in production accounted for the largest proportion of ecological footprint of water resources, reaching 82.8% - 91.4%, followed by water footprint for human. The ecological water footprint was the smallest, but it showed an increasing trend. For Anyang urban, its per capita ecological carrying capacity of water resources is small of 0.048hm2 / cap ~ 0.068hm2 / cap and fluctuate with climate and hydrological ups and downs. At the seem period, the ecological footprint of water resources are in a deficit state, indicating that the use of water resources in Anyang has long been unsustainable. In the past 10 years, theecological footprint of GDP water resources in Anyang has shown a rapid declining, which indicating that the utilization efficiency of water resources in Anyang is gradually increasing.
