摘　　要：在生态足迹分析方法基础上,建立了水资源生态足迹的计算模型,分析了安徽省2005—2013年水资源生态足迹和水资源承载力的演变历程。2005—2013年,安徽省人均水资源生态足迹整体上呈现上升趋势,人均水资源承载力呈波动变化趋势。水资源生态足迹由三个二级指标构成,包括生产用水生态足迹、生活用水生态足迹以及生态用水生态足迹。安徽省历年人均生产用水的生态足迹所占比最大,远远超过人均生活用水和人均生态用水的生态足迹,而人均生态用水所占比最小。从安徽省水资源可持续发展的三个评价指标来看,2005—2013年,全省人均水资源利用一直处于盈余状态,即历年人均水资源生态足迹均未超过人均水资源承载能力,但历年盈余程度变化较大,波幅达到1.88 hm2/人;全省人均水资源生态压力指数<1,压力指数最小的年份为0.36,最高达到0.95,接近临界状态;安徽省万元GDP水资源生态足迹逐年下降,由2005年的0.86 hm2/万元下降到2013年的0.34 hm2/万元。总体而言,安徽省水资源的利用符合可持续发展的要求,但历年降水量的不稳定造成水资源总量的时大时小,同时人均用水消耗量一直呈上升趋势,使安徽省水资源的可持续利用存在一定的安全隐患。Based on an analysis of ecological footprint, a calculation model of water ecological footprint was established. Tbe model was applied to analyze the evolution of ecological footprint and carrying capacity of water resources in Anhui province from 2005 to 2013. The results showed that per capita ecological footprint of water resources as a whole was in an upward trend, but per capita carrying capacity of water resources was volatile. Seen from the three evaluation indicators of the sustainable development of water resources in Anhui province, from 2005 to 2013, the per capita water use of the province had been in surplus, but surplus degree changed over the years; The per capita ecological pressure index of water resources 〈 1, but has been in fluctuation state over the years with the minimum of 0.36, and the maximum of 0.95; Anhui＇ s ecological footprint of water resources for every 10000 Yuan GDP has decreased year by year, from 0.86 hm2 / 10000 Yuan in 2005 down to 0.34 hm2 / 10000 Yuan in 2013.
