摘 要：
根据金海水库监测数据,参照《地表水环境质量标准(GB3838-2002)》3类标准,分别应用单因子评价法、内梅罗污染指数法和模糊综合评价法对水库水质现状进行评价。结果表明,单因子评价偏于保守,最好水质类别为Ⅱ类,最差为Ⅴ类,且不达标月份占25%。内梅罗污染指数(I_p)反映月份水质状况变化趋势,12月和次年1月I_p大于1,为不达标月份,其余月份均达标;季节I_p比较:冬季>夏季>秋季>春季。模糊综合评价体现水质好坏的模糊性,评价结果较好,最好水质类别为Ⅰ类,最差为Ⅲ类,不存在超标月份。总体来说,金海水库水质现状较好,符合饮用水地表水源标准,但部分月份存在轻度污染,应及时采取措施,确保用水安全。

摘 要：
According to Jinhai reservoir monitoring data, it applied single factor evaluation, Nemerow pollution index method and fuzzy comprehensive evaluation method to evaluate the status of water quality in the reservoir respectively referring to Surface Water Quality Standards(GB3838-2002). The results showed that, the single factor evaluation was conservative,the best water quality category was class Ⅱ,the worst was class Ⅴ, and the months below the standard accounted for 25%.Nemerow pollution index(Ip) reflected changes in water quality trends in the month, the Ipwas greater than 1 in December and January,which was not up to the standard, the rest of the month all reached the standard. Seasonal comparison of Ip:winter>summer>autumn>spring. Fuzzy comprehensive evaluation reflected the ambiguity of good and bad of water quality, the evaluation results was good, and the best water quality category was classⅠ, the worst was class Ⅲ, there was no excessive month. Generally speaking,the water quality situation of Jinhai reservoir was good, accorded with the standard of drinking surface water sources, but there was still light pollution in some months, therefore, measures should be promptly taken to ensure water security.
