摘　　要：针对小型污染场地特定组分的地下水质量评价问题,以四川西部某城镇内的污染场地及其周边区域为研究对象,选取11项评价因子(硫酸盐、氯化物、硝酸盐、亚硝酸盐、氨氮、砷、钠、铁、氟化物、挥发性酚、总硬度),通过单因子评价指数法、内梅罗指数法、修正内梅罗指数法分别对在该地区2017年丰水期所抽取的10组水样进行评价。结果显示:3种评价方法所得评价结果各有差异。单因子指数法相比内梅罗指数法其水质评价结果过分突出最差因子的贡献,修正内梅罗指数法能够解决内梅罗指数法不能反映毒理学离子对人体有害离子权重的弊病,同时经实例验证,在小型污染场地中通过修正内梅罗指数法得出的评价结果相比单因子指数法和内梅罗指数法得到结果能够反应毒理学离子的影响,评价结果更具有合理性。In order to evaluate the groundwater quality in specific components of small contaminated sites,a certain town in western Sichuan which belongs to the small contaminated sites were investigated.The authors chose 11 evaluation factors including SO4^2-,Cl^-,NO3^-,NO2^-,NH4^+,As,Na^+,Fe,F,phenol and total hardness to evaluate the water quality by using the single factor index evaluation method,Nemerow index method,corrected Nemerow index method for 10 water samples in the raining season of 2017 at this contaminated site.According to the results,the three evaluation methods showed the different outcomes.Compared with nemerow index method,the single factor index evaluation method over emphasized the contribution of the worst factor to water quality.The results of water quality evaluation obtained by corrected Nemerow index method are more reasonable than the other two methods because it can solve the problem of Nemerow index method which does not reflect the weight of harmful effects of toxicologyions ions on human body.At the same time,according to the experimental verification in the small contaminated site,it can be found that the corrected Nemerow index method can demonstrate the effect of toxicology ions.
