水库污染物允许入库负荷量是指水库水体在规定的环境目标下所能容纳的最大污染物量，它反映了水环境在满足特定功能条件下对污染物的承受能力，该值计算的正确与否是水库污染物总量控制方案成败的关键要素之一。通过选取辽宁省主要饮用水水源地-汤河水库为研究区域，建立水库污染物的允许入库负荷量的数学模型，研究分析了库区各主要污染物的年允许入库负荷量，为水库水环境治理提供科学依据。研究结果表明，汤河水库水质情况符合城市集中饮用水水源要求，根据库区主要污染物的年允许入库负荷量的计算结果并参照国家《地面水环境质量标准》（ GB 3838—2002）中的Ⅱ级水质标准，汤河水库除总氮超标外，库区其他主要污染物均有一定的纳污容量。

Allowable pollution load for reservoir is the largest amount of pollutant which can be contained by the reservoir under specified conditions.It reflect tolerance capacity of water environment for the pollutants on such con-ditions and its value is one of the key factors to make plans for total load control of the pollutants.Selected Tanghe reservoir as the study area,the annual allowable pollution load is numerically studied by using empirical model.It is found that the reservoir water quality is up to standard of drinking water for the city.Based on the research result and“Surface Water Quality Standard” ( GB 3838—2002 ) ,the reservoir has the carrying capacity for major pollu-tant except for TN.
