摘要：
In view of the uncertainty of indexes for evaluating water quality the entropy value theory is applied to combine with fuzzy matter-element method to establish an entropy fuzzy matter-element model. The coefficients of weight in this model are derived from the avail value of data reflecting the information entropy, by this method the problem of weight allocation can be avoided. The calculation result for an example is compared with those by integrated evaluating method and attribute recognition model. It indicates that the proposed method is reasonable and practical.
