摘　　要：不同的水质评价方法有不同的适用性。以桦甸市5个主要监测断面2010年枯季的监测数据为基础,选取溶解氧、氨氮等6个水质评价因子,分别采用传统、改进的内梅罗污染指数法及模糊综合法进行水质评价。结果表明3种方法评价的水质类型不同,但内梅罗法计算的污染指数大小与模糊综合法评价的水质污染程度相符。内梅罗指数法更适用于掌握水体被污染的程度,模糊综合评价法更适用于评价水体功能及水质类型。Each water quality assessment method has different serviceability.Based on the monitoring data of five major sections in dry season of 2010 in Huadian city,traditional and improved Nemerow pollution exponential methods and fuzzy comprehensive evaluation method are used to evaluate water quality by selecting six factors,such as dissolved oxygen and ammonia-nitrogen.The results show that the water quality assessment type is different with three kinds of methods;but the pollution index obtained by Merrow law method is consistent with fuzzy comprehensive evaluation method;Merrow exponential method is suitable for grasping the degree of water body polluted while fuzzy comprehensive evaluation method is more suitable for evaluating water body function and water quality type.
