摘　　要：根据多年的水质监测资料、设计水文条件及水质目标等参数,在划分容量分配控制单元的基础上,运用浅水湖泊污染物水环境容量计算方法计算了CODCr和NH3-N的环境容量,并给出了体现社会性、经济性的水环境容量分配方案,采用基尼系数法对分配方案进行公平性评估。结果表明,白洋淀南刘庄、烧车淀、采蒲台各区域的CODCr容量分别为2526.8,328.5和1430.8t/a;NH3-N容量为155.0,73.0和255.5t/a。白洋淀上游各控制单元指标的基尼系数值均小于0.4,分配结果较为合理。According to years of water quality monitoring data, designed hydrologic conditions and parameters such as water quality targets, and based on division of the control unit of distributed capacity, the capacities of chemical oxygen demand （CODcr） and ammonia nitrogen （ NH3-N） were calculated using the method of pollutant capacity estimation in shallow lakes. The water environmental capacity allocation strategies reflecting social and economic features were given and their fairness evaluated using Gini coefficient. The results showed that the capacity of CODer in Nanliuzhuang, Shaoehedian and Caiputai was 2 526.8, 328.5 and 1 430.8 t/a, respectively, and the capacity of ammonia nitrogen was 155. 0, 73.0 and 255.5 t/a, respectively. The Cirri coefficients of the control units in the upstream of Baiyangdian Lake were all smaller than 0. 4 and the allocation strategies were relatively rational.
