摘　　要：老铁山水道位于渤海海峡北部,由南部冲刷槽、北部冲刷槽和中部隆起带等三个侵蚀地貌单元构成。在前人研究的基础上,通过搜集大量相关资料,对老铁山水道的动力条件、海底地貌、沉积物组成、峡道效应及地貌形成机制进行了综合分析研究。研究区海底地貌剖面图、沉积物组成和水道动力系统可为拟议中的渤海海峡跨海通道建设提供动力沉积学和动力地貌学依据。The Lao Tieshan channel is composed of eroded valleys and ridgy zones located in the north of the Bohai strait. Based on the study of other experts on sediments and ocean currents, a lot of relative data were collected to analyze the dynamic conditions, benthonic physiognomy, sediment components, channel effects and forming mechanism. The results could provide the well-knit dynamic sedimentology and dynamic geomorphology gist for the drawing up of channel construction across the Bohai strait, which made the paper have theoretical value and meaningful to the practical application.
