摘　　要：本文通过引用国内计算污染物通量的5种主要方法,探索建立了基于水质自动监测系统核定太湖流域典型河流氮、磷等主要污染物通量的估算方法.相比传统手工监测方法,自动监测由于增加了数据频次,大量增加了水文条件和水质情况在空间和时间上的样本数量,使估算结果更具代表性.研究结果表明,基于自动监测的太湖流域各项主要污染物年通量分别为:高锰酸盐指数为2923.37t/年、氨氮为640.08t/年、总氮2777.69t/年、总磷109.91t/年.By citing five major domestic methods for calculating pollutant fluxes,this article explores and establishes a method for estimating the fluxes of major pollutants such as nitrogen and phosphorus in typical rivers of Tai Lake Watershed based on the automatic monitoring system of water quality.Compared with traditional manual monitoring methods,automatic monitoring increases the frequency of data and greatly increases the num ber of samples of hydrological conditions and water quality in space and time,making the estimation results more representative.The results indicate that the annual fluxes of permanganate index,ammonia nitrogen,total nitrogen and total phosphorus in Tai Lake Watershed based on automatic monitoring are 2923.37 tons/year,640.08 tons/year;2777.69 tons/year,109.91 tons/year,respectively.
