本文采用模糊综合评价法,并以乐安河地表水7个水质监测采样点的监测资料为依据,选择7种污染物为评价因子,分别是：DO、CODmn、CODcr、BOD5、NH3-N、Cu、Cr,运用模糊综合评判法进行评价,研究表明：清洁和未污染的监测断面占所有监测断面数量的6/7,主要分布于乐安河的上游和中游,而处于中污染的断面则分布于乐安河下游,这主要由工业废水和生活污水的大量排放所导致.评价结果与乐安河实际情况相符.研究成果可作为乐安河地表水水质综合治理的依据,也为乐安河工农业污水排放的处理及水资源合理开发利用提供了科学依据.

Adopting the ambiguous and comprehensive evaluation and taking the monitoring data of seven water quality monitoring sampling point of Surface Water in Le n River, This text has chosen the seven kinds of pollutant / contaminant as evaluation factors, such as ,DO,COD mn, COD cr, BOD5, NH3-N, Cu, Cr, and used the ambiguous / opaque and comprehensive evaluation to evaluate and research has proved : The clean and uncontaminated monitoring section occuped six to seven of all the monitoring sections ,which were mainly distributed on the upstream and midstream of Lean River.
The fracture surfaces /sections / planes of fracture with middle-degree contamination were distributed in downstream of Lean river ,which has resulted from the magnaimous drainage /emission of industrial wasted water / sewage /effluents and domestic sewage, The evaluation result has conformed to the actual condition , Research achievements can be served as the foundation and evidence of comprehensive harnessing of the quality of the surface water in Lean River and provide the scientific basis for the treatment of drainage of industrial and agricultural sewage in Lean river and sound and reasonable development of water resources . 纯人工翻译,如果满意,请及时采纳,谢谢!
