| 摘 要： | 根据水资源承载力分析的结构特点,在传统多目标分析决策技术的基础上,将熵值法与属性识别模型相结合,建立了基于熵权的属性识别水资源承载力评价模型,应用熵值法来确定权重系数,避免了权重系数确定的主观性问题,用一种新的方法进行水环境承载力评价.结合实际应用的结果表明,其评价结果合理,适用于水环境承载力评价.

| Abstract: | According to the framework for multi criteria decision analysis in water carrying capacity,the entropy value theory and the attribute recognition model were combined together,and a model for evaluating water resources bearing capacity based on coefficient of entropy was set up. The law of entropy value was employed to calculate the coefficient of weight. The method avoids the subjectivity on calculation of coefficient of weight, and its application indicates that it is suitable to evaluate water resources bearing capacity. |
