摘要
利用多层次评价法甄选与湘江长株潭段密切相关且关联系数超过0.51的指标,赋予相应的权重值.通过建立灰色束函数和灰色矩阵计算重金属污染下湘江长株潭段水资源开发潜力大小.结果表明,多层级灰色理论可用于对水资源开发潜力的评价过程中.湘江长株潭段水资源开发潜力系数为2.983,属于次高层级范围[2.500,3.250]之内,说明湘江长株潭段水资源开发潜力在一定时间范围内都比较高.
The indices （correlation coefficient ＆gt; 0.51）,which are related to the Chang-Zhu-Tan section of the Xiangj iang River,were selected by using the analytic hierarchy process.The weight values of these indices were given according to their importance.The water resource development potential of the Chang-Zhu-Tan section of the Xiangj iang River was calculated by establishing Gray beam function and Grey matrix.The results have shown that the water resource development potential can be evaluated with the Multi-level Grey theory.The water resource develop-ment potential in the Chang-Zhu-Tan Urban Agglomeration is 2.983,which belongs to the second-highest range [2. 500,3.250].This indicates that the water resources of the Chang-Zhu-Tan section of the Xiangjiang River are higher within a certain time range.
