| 摘 要： | 针对水资源丰富程度评价中的不确定性及水资源分布特点,将集对分析中的五元联系数法应用于水资源丰富程度评价。在确定各评价指标的权重时,将信息论中的熵值理论引入该模型,运用信息熵所反映实测数据的效用值计算各评价指标的权重。通过对郑州市的实例应用表明基于熵权的五元联系数法计算简便,评价结果合理,为水资源丰富程度评价提供了一种简单而实用的评价方法。

| Abstract: | In view of the uncertainty of evaluation indicators for water resources richness assessment and water distribution characteristics, five-element connection number is adopted. The entropy weights of evaluation factors in the model are obtained from the avail value of data reflecting the information entropy. The case studies show the proposed method is simple calculation and reasonable assessment result. A simple and practical evaluation method for water resources richness assessment is provided. |
