基于熵的模糊物元水资源承载力评价

Assessment on Water Resources Carrying Capacity by Entropy-based Fuzzy Matter-element

用基于信息熵理论的模糊物元分析法进行区域水资源承载力综合评价,并在此基础上进行合理的改进和运用,结合欧氏贴近度实现不同评价分区的量化比较,得到各分区水资源承载力水平及其优劣次序。实例表明,相对于常规的灰色物元分析法、模糊综合评价法等,该方法更能反映问题实质,评价结果合理,有助于塔里木河流域的水资源利用与经济社会发展的协调。

The information entropy theory is introduced into the fuzzy matter-element analysis that has been successfully used in comprehensive evaluation with multiple indicators to assess regional water resources carrying capacity.On this basis,through rationality improvement application and the Euclid Approach Degree to realize the quantitative comparison for the different regions and achieve the level of water resources carrying capacity and the merits order rank.The study shows that compared with grey matter-element analysis approach and fuzzy comprehensive assessment approach,the results of entropy-based fuzzy matter-element analysis are better to reflect the essences of the issues and more scientific and rational,which is useful for solving the water resources issues of Tarim river basin.
