摘    要:珠江口伶仃洋四口门是珠江三角洲主要的泄洪纳潮通道,其水动力环境的变化是伶仃洋冲淤演变最直接原因,而伶仃洋的冲淤演变会关系到伶仃洋口门泄洪纳潮的能力,关系到珠江三角洲的防洪、排涝和经济发展等,根据实测资料及已有的研究成果,分析伶仃洋周边环境的变化原因,从河口地形的冲淤演变分析伶仃洋周边环境及其水动力环境的改变,并探讨伶仃洋河口整治策略。认为应采取输沙导流措施,减少淤积,保证口门通畅,保持伶仃洋潮流动力。

关 键 词:伶仃洋  水动力环境  排涝  河口整治  冲淤演变

Abstract:The four outlets of the Pearl River in Lingdingyang Bay are the main passages for flood disposal and tide carrying in the Pearl River Delta, change of hydrodynamic environment of which is the most direct cause for evloution of silting and scouring in lingdingyang Bay, in him, the latter will affect the oudets in capacity of flood disposal and tide carrying and also flood control, waterlogging discharge and economic development in the Delta. Based on measured data and research results available, this paper analizes the causes of change in the surrounding environment of Lingdingyang Bay and its change in hydrodynamic environment according to the evolution of esturine topography in silting and scouring. Improvement strategy is discussed for Lingdingyang outlets. It is recommanded measures for discharging sediment and diverting water be taken to reduce siltation and ensure the outlets unobstructed so as to maintain motive force of tidal current in the Bay.
Keywords:Lingdingyang Bay  hydrodynamic environment  scour and silting  improvement strategy
