松花江流域融冰期水质分析

Analysis on water quality during melting ice of Songhua river basin

文中选择溪浪口、松花江和松林三个松花江流域水质自动监测站2014年至2018年的氨氮量变化作为研究对象,分析每年3月融冰期氨氮变化水质情况。研究结果表明:融冰期汇流与产流过程会携带更多污染物入江;溪浪口、松花江和松原站融冰期3月氨氮浓度平均值分别高于样本总体数据的80.9%、78.0%和78.0%。

This paper selected ammonia nitrogen content from 2014 to 2018 at three automatic monitor stations,Xilangkou,Songhua river and Songlin in Songhua river basin as the research object to analyze the change of ammonia nitrogen in water quality during the melting period in March every year.The results show that the confluence and generation of melting ice will bring more pollutants into the river.The average ammonia nitrogen concentration in Xilangkou, Songhua river and Songyuan station in March was higher than 80.9%, 78.0% and 78.0% of the total sample data respectively.
