摘　　要：为了研究青草沙水库原水中氮和磷的动态变化特征,在青草沙水库中选择了具有代表性的6个监测点,分别对氨氮、亚硝酸氮、硝酸氮、TN、DP、TP等营养盐指标进行动态监测,并分析了不同监测点氮、磷动态变化特征及氮磷比。其结果表明,青草沙水库中氨氮含量低于0.45mg/L;亚硝酸氮与硝酸氮含量分别在0.1mg/L和2mg/L以下;总磷浓度低于0.2mg/L;并初步推算磷为富营养化的限制因子。因此,青草沙水库水质较好,适合作为上海新水源地。To study the changing features of N,P in Qingcaosha reservoir,6 representative monitoring points were chosen.And the water standard such as ammonia nitrogen,nitrite,nitrate,TN,DP and TP were monitored in order to analyze the variation of TN,TP,TN/TP.The results showed the concentration of ammonia nitrogen in Qingcaosha reservoir is lower than 0.45 mg/L,while the nitrite and nitrate is lower than 0.1 mg/L and 2 mg/L respectively,and the TP concentration is lower than 0.2 mg/L.So conclusions can be drawn that P is the limiting factor of eutrophication and the water quality in Qingcaosha reservoir is suitable as new drinking water resource of Shanghai.
