基于模糊综合评价法对丹江口水库陶岔水质的富营养化评价

Eutrophication evaluation for Taocha water quality in Danjiangkou reservoir based on fuzzy comprehensive evaluation method

针对水质富营养化评价指标的不确定性,运用模糊综合评价法对丹江口水库的富营养化状况进行评价.采用改进的层次分析法确定各指标权重,并构造岭形函数确定隶属度,在一定程度上避免了主观干扰的因素.经数据验证,该方法对水质的富营养化评价结果合理有效.

Based on the uncertainty of water quality eutrophication evaluation index, this paper evaluates the eu- trophication status of Danjiangkou reservoir by fuzzy comprehensive evaluation method. The improved analytic hi- erarchy process （AHP） is used to determine the weight of each index, and the ridge shape function is used to determine the membership degree, which avoids the subjective interference factor to a certain extent. The results show that the method is effective for the eutrophication evaluation of water quality.
