摘　　要：以中山市为例,采取引水调控措施改善该市河涌水环境,结合河网地区水利设施,建立水量水质联合调控模型,通过二级联解方法,模拟引水调控实施效果。结果表明:在枯水期实施引水调控36h、汛期实施引水调控12h后,该市河涌水质能达到水功能区的水质目标。引水调控措施增加河涌水动力、提高水环境容量,可有效改善河涌水环境。Water diversion and regulation measures were proposed In branches in Zhongshan City. Based on the water conservancy facilities and quality regulation model was established to simulate the effects of order to improve the water environment in fiver in the fiver network region, a joint water quantity water diversion and regulation using the two-step method. The results show that through water diversion and regulation for 36 hours in the dry season and 12 hours in the flood season, the water quality in the fiver branches in the city can satisfy the requirement of the water functional area. The water diversion and regulation have increased the hydrodynamic force, enhanced the water environmental capacity, and effectively improved the water environment in the fiver branches.
