摘要
通过耦合水足迹理论与主成分分析方法,构建基于水足迹的新疆地区水资源承载力评价指标体系,分析研究区2010~2015年间水资源承载能力变化情况。结果表明:2010~2015年间新疆地区的水资源承载力呈先增大后减小的现象,2014年水资源承载力最差,供水压力最大。其中,研究区的承载力主要受水资源和社会因素以及进出口贸易中虚拟水的影响,贡献度分别为56.791%、22.724%。另外,外部水足迹约占水足迹总量的10%,表明研究区出口产品中的水约占总水资源量的10%。
By coupling the water footprint theory and principal component analysis method,this paper constructed an evaluation in-dex system of water resources carrying capacity(WRCC)in Xinjiang and analyzed the changes in WRCC during 2010-2015.The results show that the WRCC increased first and then decreased from 2010 to 2015.The WRCC was the worst while the water supply pressure was the largest in 2014.The carrying capacity is mainly affected by water resources and social factors,as well as virtual water in import and export trade.The corresponding contributions are 56.791%and 22.724%respectively.In addition,the external water footprint accounts for about 10%of the total water footprint.It reveals that the water in the export products of the study area accounts for about 10%of the total water resources.
