摘　　要：基于2009年10月26—28日太湖重污染区野外水文、水质同步监测数据,分析水量水质现状,建立一维水环境数学模型,并计算不同污染控制方案下水质(总氮)的改善效果。计算结果表明:现状污染物排放方案及污染物总量达标控制方案不能完全控制入湖断面总氮,鉴于河流水质总氮因子没有明确的地表水环境质量标准,必须在污染物总量达标控制方案基础上制定更严格的入湖控制断面水质功能区达标方案。水质功能区达标方案的实施可以有效地改善入太湖控制断面总氮状况,基本实现河网水质达到功能区水质目标。Based on hydrological and water quality monitoring data of a heavily polluted area in Taihu Lake from October 26 to 28 , 2009 , the water quantity and water quality in the heavily polluted area were analyzed , and a one-dimensional water environmental mathematical model was established to simulate total nitrogen （ TN） with different pollution control schemes .The results show that the current pollutant discharge scheme cannot meet the standard for TN discharge into the lake .In view of the lack of surface water quality standards for TN in rivers , we must work out a standard-reaching scheme that is stricter for water quality in water function zones based on the total pollutant standard-reaching scheme .This scheme can effectively improve the water quality （ TN） of water discharged into Tiahu Lake and enable the water quality of the river network to reach the standards of water function zones .
