摘　　要：为了更好地掌握木兰溪流域的水质情况,采用单因子评价法、水质综合指数法、模糊综合评价法和模糊聚类法等4种方法,分别对该流域内2018~2020年蒋隔水库、濑溪、木兰溪三江口、仙游石马桥、仙游西台桥和园头桥等6个监测断面的水质进行了评价。结果表明:单因子评价法能直观的看出主要污染指标,水质综合指数法可对相同等级的水质样本进行进一步的比较,模糊综合评价法和模糊聚类法考虑了水质评价中的不确定性和模糊性,但模糊聚类法不适用于对水质进行精准的分级评价。通过对比不同水质评价方法在木兰溪水环境中的应用和适用性,使评价结果更加客观实际。Water quality of six monitoring sections in Mulan River basin during 2018 to 2020,including Jiangge Reservoir,Laixi River,Mulan River Sanjiangkou,Xianyou Shima Bridge,Xianyou Xitai Bridge and Yuantou Bridge,are evaluated with single factor evaluation method,water quality index method,fuzzy comprehensive evaluation method and fuzzy clustering method to study the water environment of Mulan River basin.The results show that the single factor evaluation method can intuitively reveal the main pollution indicators,the water quality index method can further compare the water quality samples of the same grade,the fuzzy comprehensive evaluation method and the fuzzy clustering method take into account the uncertainty and fuzziness in the water quality assessment,but the fuzzy clustering method is not applicable to the accurate grading evaluation of water quality.The comparison of the application and applicability of different water quality assessment methods in the water environment of Mulan River makes the assessment results more objective and practical.
