摘　　要：考虑河流致黑致臭成因的模糊性和不确定性,以及干旱地区河流黑臭成因的复杂性,应用熵权赋权法确定各个评价指标的权重,建立基于熵权的物元可拓模型进行干旱地区河流黑臭评价。以具有代表性的丹河晋城河段为研究对象,设置赵庄、东焦河水库出口、高平河西、任庄水库、白水河5个监测断面,对其丰水期、平水期、枯水期水质进行现场监测,选取BOD、COD、NH3-N、Mn、DO、CH、Fe、P为评价指标进行河流黑臭评价。评价结果表明:模型预测结果与实际情况吻合较好,预测精度较高。Considering the fuzziness and uncertainty of reasons for river black-odor and the complexity of reasons for black-odor of river in arid areas,a method of entropy weight to determine the weight of each evaluation index was applied with the matter-element extension model based on the entropy weight to estimate the black-odor level of river in arid areas. Besides this,Jincheng section of Danhe River was select-ed as a representative research object where built 5 monitoring sections in Zhaozhuang,reservoir outlet of Dongjiao River,Renzhuang Reser-voir,west of Gaoping River and Baishui River. Through investigation and water quality monitoring in wet season,normal season and dry sea-son,BOD,COD,NH3 -N,Mn,CH,DO,Fe,P were selected as the evaluation index to evaluate the level of black-odor river. The re-sults show that the prediction results are consistent with the actual situation and the accuracy is higher.
