摘　　要：俞塘河是上海市西南部的一条东西向河流,流经松江区。本文选取俞塘河作为研究对象,将其与新车公路的交汇点(新车公路桥)作为监测点位,分析浮标水质监测站在河流氨氮连续监测中的应用。监测数据显示,2021年,氨氮浓度年均值为0.65 mg/L,月均值介于0.37~1.06 mg/L,其中最高值出现在2月,最低值出现在4月。全年第3季度高值易发时段是08:00—18:00,发生率为80%左右,其他季度高值易发时段是00:00—07:00。研究表明,浮标水质监测站可以应用于河流水质监测,俞塘河水质长期满足《地表水环境质量标准》(GB 3838—2002)的Ⅲ类水质要求。Yutang River is an east-west river in the southwest of Shanghai City,flowing through Songjiang District.This paper selects Yutang River as the research object,and takes its intersection with Xinche Highway(Xinche Highway Bridge)as the monitoring point,so as to analyze the application of buoy water quality monitoring station in the continuous monitoring of ammonia nitrogen in the river.The monitoring data shows that in 2021,the annual average concentration of ammonia nitrogen is 0.65㎎/L,and the monthly average is 0.37~1.06 mg/L,with the highest value in February and the lowest value in April.In the third quarter of the year,the high value period is 08:00—18:00,with an incidence of about 80%,the high value prone period in other quarters is 00:00—07:00.The research shows that the buoy water quality monitoring station can be applied to water quality monitoring of rivers,and the water quality of Yutang River has long met the ClassⅢwater quality requirements of the"Environmental Quality Standard for Surface Water"(GB 3838—2002).
