摘  要:
水足迹可从人类产品消费量和消费模式角度衡量区域水资源利用效率。近年来河南省水资源匮乏状况日渐加剧,为使决策者对河南省水资源利用状况有一个清晰的认识,基于水足迹理论,运用M-K突变检验和系统聚类法对河南省水足迹结构、效益和生态安全三方面在时间及空间维度进行综合评价。结果表明:河南省水足迹呈增加趋势,在2006年发生突变,2009年达到1 382亿m3,内部水足迹起决定作用;水足迹增长超出了省内水资源负荷,2003年以后水资源超采现象更加突出;河南省水资源消耗量增大的同时水资源利用效率也有所提高。全省各地市水资源利用的空间差异明显,驻马店和周口水资源利用效率很低,水资源消耗总量最大;郑州、三门峡和洛阳的水资源利用效率较高;驻马店、商丘的水资源依赖度最小;漯河、许昌水资源匮乏指数最大的同时水资源依赖度却较低,水资源超采严重。为了改变水资源利用效率低、超采严重的现状,河南省各地需要加强水资源的合理配置和高效利用。

摘  要:
The water footprint can measure the efficiency of regional water resources from the point of view in amount and patterns of human product consumption.In recent years,water resources shortage in He′nan Province has been intensified.Based on the theory of water footprint,water footprint calculation results in structure,benefit and ecological safety were evaluated by M-K verification and hierarchical clustering method from temporal and spatial sequence so that policy makers have a clear understanding of water resources utilization in He′nan.The results showed that:water footprint in He′nan Province showed an increasing trend,water footprint in 2009 was 1.382×1011 m3,additionly,the abrupt change points of which occuured in 2006;the internal water footprint played a decisive role in water footprint growth;water footprint growth had been beyond the water resources load so that water resources were over exploited seriously from 2003;consumption of total water resources was increasing,at the same time,efficiency of water resources was also improved.The water footprint index spatial clustering in 2009 results showed that:efficiency of water resources in Zhumadian and Zhoukou was very low so that its water resources consumption was the largest;efficiency of water resources in Zhengzhou,Sanmenxia and Luoyang was larger;local water resources in Zhumadian and Shangqiu are highly depended;water resources in Luohe and Xuchang were over exploited seriously.In order to change the present situation of water resources in He′nan Province,rational allocation and efficiency of water resources need to be strengthened.
