摘　　要：为提高枯水期南昌市水环境承载力,构建了赣江尾闾水环境数学模型,研究了不同水文条件的优化调度方案。结果表明,在流量小于1020 m^(3)/s时,赣江主干河流和下游主、北、中、南四个分支最佳调度水位在最低生态水位和警戒调控水位之间,调度时间在1.11 d以内;在流量大于1020 m^(3)/s后时,警戒调控水位即为防洪限制水位,主干河流和四个分支的最佳调度水位在最低生态水位和防洪限制水位之间,调度时间在4~7 d内。建议各分支拦河枢纽靠近警戒调控水位运行,既能保证河流控制断面水质达标,又能最大限度的保持南昌市水资源可利用量。In order to improve the water environment carrying capacity of Nanchang during the dry period,this paper constructed a water environment model at the lower end of the Ganjiang River and proposed an optimal scheduling scheme.The results show that the optimal scheduling water levels for the Ganjiang main river and its four downstream branches-the main,the north,the middle,and the south-were between the minimum ecological water level and the alert control water level,and that the scheduling time was within 1.11 days when the flow rate was less than 1020 m^(3)/s.Conversely,when the flow rate was greater than 1020 m^(3)/s,the alert control water level was the flood control limit water level.The optimal scheduling water levels of the main river and the four branches were between the minimum ecological water level and the flood control limit water level,and the scheduling time was within 4-7 d.It was suggested that each branch barrage hub should be operated close to the alert control water level to ensure that the water quality of the river control section meet the standard,and to maintained the maximum amount of water resources available in Nanchang.
