摘　　要：基于SPSS主成分分析法对海浪河流域水节霉生长水体水质进行评价。在12月份,对海浪河流域10个断面的水质指标进行评价,结果表明,英雄桥和斗银河口断面污染较严重,主要污染物为氮和有机物,其余断面水质较好,基本满足功能需求;同时对水节霉惟一生长地河夹村大坝连续进行6个月的水质监测,结果表明,在冰封期的1~2月份,该断面污染比较严重,污染物特征与海浪河流域相似。特定的氮源和有机物是水节霉形成优势种群的主要原因之一。The quality of water body with Leptomitus lacteus growth in the Hailang River was evaluated based on principal component analysis method.In December,ten sampling sections of Hailang River were selected for the evaluation of water quality indexes.The results showed that the water of Yingxiong Bridge and Dou Yin He Kou were seriously polluted with the main pollutants of nitrogen and organics.The water quality of other sampling sections were better,which could meet the water body basic functions and requirements.At the same time,monitoring the water quality of Hejia Village Dam was carried out for 6 months.The monitoring results showed that the water of Hejia Village Dam was seriously polluted in the freezing period,i.e.January and February.The characteristics of the pollutants were similar to those of Hailang River in freezing period.Some certain nitrogen sources and organics were one of the major causes of the dominant growing of Leptomitus lacteus.
