针对国内水资源紧缺现状,基于水足迹理论建立了水资源紧缺度评价指标,分析确定了相应的评价标准,采用物元分析法对水资源紧缺度进行了量化计算。以江苏省为例绘出了2005～2009年间水足迹评价指标变化的折线图,计算分析了各年的综合关联度,得出了江苏省的水资源紧缺程度,从降低水足迹角度提出了应对水紧缺状态的建议。
In view of the current shortage of water resources in our country, a water shortage index was established based on the water footprint theory. The corresponding evaluation criteria were analyzed and determined. Quantitative analysis of water shortage was carried out by using matter element analysis. Taking Jiangsu Province as an example, this paper draws a line chart of the change of water footprint evaluation index from 2005 to 2009, calculates and analyzes the comprehensive correlation degree of each year, and draws a conclusion that Jiangsu Province has a shortage of water resources and proposes measures to reduce water footprint Water shortage status of the proposal.
