摘　　要：针对单一评价方法的局限性,以沈阳市4个自来水厂16例监测井为对象,采用单项水质指数法、国标F值法和灰色关联评价法对沈阳市2010年枯水期地下水水质进行综合评价。选择氨氮、硝酸盐、硫酸盐、p H值、总硬度、总铁、锰7项指标作为评价因子。结果表明,3种方法联合使用更能真实地反映水质状况。国标F值法得出,评价结果中Ⅳ类为43.75%,Ⅱ类为37.5%,Ⅴ类为12.5%,Ⅰ类为6.25%,评价结果为水质较差;灰色关联评价法得出,Ⅰ类为62.5%,Ⅱ类为18.75%,Ⅲ类为12.5%,Ⅳ类为6.25%,评价结果为水质较好。由此得出,灰色关联评价法评价结果较差,则水质状况较差;国标F值法的评价结果较好,则水质状况较好;当灰色关联评价法评价结果较好,而国标F值法的评价结果较差时,则水质状况有恶化的趋势。根据单项水质指数法评价结果,能清晰地看出水质指标的超标情况。根据评价结果,沈阳市二水厂4个监测井的水质均较好,一水厂和八水厂有1个监测井水质较差,四水厂有两个监测井水质较差。除氨氮、总铁和锰等指标严重超标外,其他水质指标状况较好。This article is aimed to make an assessment of the ground- water quality via the comprehensive assessment of the groundwater quality in Shenyang instead of using the limited single assessment method. In this paper, we have chosen the groundwater quality moni： toting data of 16 monitor wells from the 4 drinking water plants in the city in the dry seasons in 2010 by using the single water quality index method, in contrast with the GB F value method and the gray relational assessment method. The evaluation factors that we have adopted involve ammonia nitrogen, nitrate, sulfate, pH, total hardness, total iron and manganese. The results of our assessment have shown that the water quality we have assessed tend to be more accurate by the three methods in an integrated way, though the use of GB F assessment method may not sound very desirable. Our assessment results demonstrate that 37.5 % of the groundwater quality turns out close to the second state-grade for the drinking water criteria. However, 43.75% of it can hardly be made to be in accord with or over grade IV, the targeted standard. And 12.5% of it can get to the standardized grade V. On the whole, the results of our assessment can be thought successful by using the gray relational evaluation method. And, 62.5 % of it has come to the standard grade I. There was only 6.25% of its quality was just close to the standard grade IV. Therefore, the water quality of the whole city should be consid- ered comparatively poor in quality if the results were to be assessed with the gray relational assessment method. However, the result of the assessment should be considered nice by using GB F value method. Moreover, no matter whether we tend to assess the results by using the gray relational assessment method or by using GB F value method, it should be believed that the water quality has been deteriorating. On the other hand, if we use the single water quality index method, the water quality should be said to get elaborated in detail. All in all the water quality is good fro
