摘　　要：目的建立"单点-区域水质评价"模式,并对一起水体污染实例进行评价。方法选择环境污染水体超标项目和特征性污染物共15项理化、毒理学指标作为检测评价指标,检测污染区(88户)和对照区(10户)井水水质;采用"改良内梅罗指数法"先对单点水质进行评价,再对区域总体水质进行综合评价。结果污染区88户村民井水有3户呈现中度污染,8户呈现重度污染,区域总体水质为中度污染。结论该区域村民井水总体水质受到一定程度污染。"单点-区域水质综合评价"模式可应用于农村区域水质评价。Objective To establish an assessment model for single sample water quality and regional water quality evaluation and evaluate a water pollution accident using the established method. Methods Environmental water pollution and characteristic pollutants which included 15 physieoehemical and toxicological indicators were selected as the detection items, well water of 88 households in the polluted area and 10 households as the control group were collected for determination. The assessment model for single sample evaluation and the regional water quality evaluation was established using the improved Nemerow index method. Results In the polluted area, three of the 88 well water samples were moderately polluted,eight were severely polluted,and regional water quality revealed moderate pollution. Conclusion The well water in the polluted area was polluted. The model for single sample and regional water quality evaluation can be applied to water quality evaluation in rural area.
