中小型入海河流数量众多,每年输运大量沉积物、营养盐与污染物入海,会对河口海岸地区的地貌演化、自然资源开发与生态系统平衡产生重要影响. 在入海河口建闸,改变原有的物质输运格局,将产生一系列需要治理的河口问题,如河口淤积、污染、生态系统退化等. 以盐城海岸主要入海河口为例,分析了建闸河口的主要特征,提出了建闸河口可持续治理概念与对策措施,以确保河口地区经济社会可持续发展.

There are a lot of small and medium-sized estuaries, and they transport giant sediments, nutritive salts and pollutants into the ocean, which could cause great impact on the geomorphology evolution, natural resources exploitation and the balance of ecosystem.Building tidal sluices at the estuaries could change the original sediment transport patterns, resulting in a series of estuary problems, for example, estuary siltation, pollution and degeneration of ecological system.Taking main estuaries of Yancheng coast for instance, the characteristics of estuaries with tidal sluices were analyzed, and the concept of sustainable improvement and corresponding countermeasures were proposed, in order to ensure the sustainable economic and social development of the estuary areas.
