摘　　要：为了研究进入洱海河流污染物对洱海的影响,利用分担率法构建了洱海水动力水质模型,结合洱海污染负荷、水文气象特征,计算了洱海水环境容量。结果表明:在Ⅱ类水质目标下,平水年(2004年)中部湖区作为控制点时入湖河流可承担的COD、TN、TP水环境容量总和分别为16 338.11、11 643.84、620.39 t/a,其中弥苴河的水环境容量最大。同一特征水位、同一水平年条件下,洱海中部水环境容量最大,南部次之,北部最小;同一特征水位下,同一区域的主要污染物水环境容量随水文条件呈现出"丰水年>平水年>枯水年"的态势。In order to study the influences of pollutants in the rivers flowing into Erbai Lake, Erhai hydrodynamic and water quality model was es- tablished with the method of sharing rate method, Erhai environmental capacity was calculated combined with the Erhai pollution load, hydrological and meteorological characteristics. The results showed that in order to ensure the class water II quality, the total amount of COD, TN, TP the river can take is 16 338.11, 11 643.84, 620.39 t respectively in average year（2004）, the water environmental capacity of Miju River is the biggest. The water environmental capacity of central Erhai is the biggest and the southern takes second place, the northern is the least in the same character- istic water level and same level year; water environment capacity with the hydrological conditions showing a ＂wet year 〉 average year 〉 dry years＂ trend in the same characteristic water level and sameregion.
