摘　　要：传统的水环境容量核算一般以一定保证率下的设计枯水流量为计算条件,存在水文计算条件单一、水环境容量不易管控等不足。本文通过滦河流域污染排放调查核算,基于QUAL2K模型建立水质模型,对流域水质进行逐日模拟,并根据模拟结果计算滦河流域主要河流逐日COD、氨氮和总磷的水环境容量。本研究计算的动态水环境容量能够较为客观地反映水文条件变化下的动态水环境容量,给出满足河道水质目标前提下逐日入河污染物允许阈值,为流域水环境保护与精细化管理提供数据支撑。The traditional water environmental capacity is calculated based on a designed dry water flow at a certain hydrological guarantee rate,which is difficult to control the capacity under different flow regimes.This research combined QUAL2K model and pollution discharge investigation,to simulate the daily hydrological and water quality situation in the Luanhe River basin.And the dynamic water environmental capacity of COD,NH3-N and TP was calculated according to the simulation results.The results suggested that the dynamic water environmental capacity can objectively reflect the effects from variational hydrological conditions,and provide more reasonable allowable threshold values of pollutants discharge into the river.This research afforded data support and new ideas for water environmental protection and fine management in the basin scale.
