摘　　要：马口水文站是西江进入珠江三角洲网河区的一个重要控制站,位于珠江三角洲河口区西江干流水道,上游来水来沙情况对马口站水沙特性影响显著。采用马口站与上游控制站多年实测资料,通过上下游对照分析、单站分析等方法,初步探讨了西江泥沙的主要来源、年内变化、粒径变化等时空演变的规律及影响要素等,揭示了西江流域各河流控制站的水沙演变特性。Makou hydrologic station is an important control station of the West River enters to the river network of the Pearl River Delta. It is locating in the estuarine area of Pearl River Delta and West River main stream channel. The condition of upstream runoff incoming water and sediment is significantly to the Makou station ＂s water and sediment changes. This paper adopts measured data over the years of the Makou station and upstream control station, through the comparative analysis on the upstream and downstream, single station analysis method, preliminary discussed the evolution law and influence factors of West River, including the main source of sediment, annual variation and variation of particle size , reveals the water and sediment evolution in the control stations of West River basin.
