摘　　要：以苏州城区29条景观河道为研究对象,分别以单因子评价法和黑臭判别式法对其水体表观质量进行评价。单因子评价法的评价结果主要为Ⅴ和劣Ⅴ类,区分度不高;五种黑臭判别式吻合率分别为60.3%、71.6%、66.0%、60.3%、72.8%,且仅能判断是否黑臭;二者均不能准确描述水体表观质量变化进程。基于以上情况,提出了水体表观质量综合评价指数法(SQI),其评价结果与水体表观现场评价吻合率为82.5%,整体上与公众主观感受一致;表观质量指数区分度明显,能够反映水体表观污染效应渐变过程。29 landscape rivers in Suzhou, which were chosen as the study objects, were evaluated by single factor evaluation method and black-odor discriminant method, respectively. The results showed that these two methods could not describe the variation process of sensory quality of urban water bodies because of low differentiation of single factor evaluation method and low fitting degree of black-odor dis- criminant method. The fitting rates of five black-odor discriminants were 60.3%, 71.6%, 66.0%, 60.3% and 72.8% respectively. A comprehensive index assessment method to evaluate the sensory qual- ity of urban water bodies was proposed according to the problems above. The assessment results of the method agreed well with the sensory evaluation in the field with an agreement of 82.5% , which was con- sistent with the public subjective sensation as a whole. Due to the significant differentiation of sensory quality index, the method can reflect the degree and the process of apparent water pollution.
