摘要： 通过4年枯、丰、平3个水期72次DO、COD、BOD、NO3--N、NO2--N、NH3-N、Cu++、Pb++、Cr+6、总As和SS监测,从获得的近1980个有效数据中,研究5个监测断面,优化出最有代表性为对照断面和出境断面,从而就可以测知各类污染物的时间差异变化及控制氮化物的指标。

关键词: 红河, 水期, 污染物, 变化规律

Abstract: Nearly 1980 effective data were obtained through 72 times observation on DO, COD, BOD, NO3--N,NO2--N, NH3-N, Cu2+, Pb2+, Cr6+, T- As and SS in three water periods, namely dry, normal andwet, in four years. After studying 5 monitoring section, optimizing the most representative contrast sectionand exit section, temporal change for various kinds of pollutants is analyzed and control index for nitride is proposed.

Key words: Red River, water period, pollutant, change pattern
