摘　　要：基于对沙颍河安徽段污染负荷的调查以及水质和流量监测数据的分析,采用MIKE11模型建立水流与水质模型,采用线性规划法,以入淮河干流Ⅲ类水为水质目标,计算沙颍河安徽段水环境容量并分析其动态特征。结果表明:沙颍河安徽段CODMn和氨氮年水环境容量分别为2.39万、0.76万t/a;受流量及上游水质影响,CODMn和氨氮水环境容量月变化较大,8月水环境容量最大,分别为3 557、1 363 t,3月水环境容量最小,分别为621、181 t;上游水质对沙颍河安徽段水环境容量影响显著。Water flow and contaminant transport were simulatedby using MIKE11 based on the measured river discharge and concentration of CODMn and ammonia in the Shaying River basin of Anhui Province. The water environmental capacity of the Shaying River basin in this region was estimated by using the linear programming method with respect to the category Ⅲ of the water quality target of Huaihe River. The results show that the water environmental capacities of CODMn and ammonia are 23 900 t/a and 7 600 t/a respectively. The water environmental capacities of CODMn and ammonia fluctuate dramatically with the changes of the discharge and water quality of the upstream. The maximum water environmental capacities of CODMn and ammonia appear in August,showing 3 558 t and 1 363 t respectively,while the minimum ones appear in March,showing 621.8 t and 180.6 t respectively. The water quality of the upstream has a significant influence to the environmental capacity of the downstream of the river in Anhui Province.
