芦潮港车客渡码头水域近期强势淤涨原因辨析

叙述了１９９３年前的芦潮港车客渡码头水域自然水深条件和１９９３年后强烈淤涨的态势，从诸事件的时间之窗及水下滩坡适应性调整、长丁坝促淤效应等方面讨论了该水域强势淤涨的原因，提供了一个海岸工程产生淤积响应的典型实例。海岸带（尤其在沉积环境响应敏感的区域）开发必须注重社会经济效益与环境效益的统一。

Cause of recent strong siltation in the Luchaogang boat ferry waters

The natural depth condition before 1993 and strong siltation situation since 1993 in the Luchaogang boat ferry waters are described in this paper. The major factors leading to sharp increase of siltation are discussed no the basis of time series of the events, self adjustment of submarine slope and effect of a long groin. The paper presents a typical example about siltation impact of coastal engineering structures. It must be paid attention to unity of social economic benefit with environmental benefit in development of coastal zone, particularly the coastal area being sensitive to deposition environment.
