摘　　要：针对动态水环境容量特点,结合水体污染负荷控制要求,探讨满足不同水质管理目标的水容量总量计算的水文条件设计方法。研究借鉴国内外容量总量计算设计水文条件确定原则,针对多类型水文数据及控制性水工程调控情景,给出符合浑太河流域水体类型特点,满足流域水量和水体污染物变化过程连续性的设计水文条件。合理确定断面的设计流量是计算水环境容量的关键。在确定流域典型污染物分期、分区设计参数的基础上,结合水环境容量时空变动特点,动态计算水环境容量。浑太河流域COD水环境容量总量为144 626 t,枯水期、平水期、丰水期水环境容量分别占总量的16.2%、35.4%、48.4%;氨氮水环境容量总量为9 776 t,枯水期、平水期、丰水期水环境容量分别占总量的16.2%、35.4%、48.4%。动态水环境容量结果的合理性成为判定设计水文条件可靠性的主要依据。According to the characteristics of dynamic WEC, this paper offers the way to design hydrological conditions, combined with the water pollution load control requirements. Based on domestic WEC calculation standard, existing techniques and other hydrological condition design principles, this paper gives hydrological conditions design process to meet the water-body and chemical changes. The determination of hydrological condition of cross-section has become the key to calculate the WEC. As for Huntai River watershed, the WEC of COD is 144 626 t, and WEC in low-flow period, level period, and high-flow period accounts for 16.2%, 35.4% and 48.4% respectively. The WEC of amino -nitrogen is 9 776 t, and WEC in low-flow period, level period, and high-flow period accounts for 16.2%, 35.4% and 48.4% respectively. The rationality of dynamic WEC results has become a basis for judging the reliability of hydrological conditions design.
