摘　　要：近年来,马鞍山郑蒲港港池河床持续淤积抬高,给港区生产安全带来隐患。为分析郑蒲港淤积产生的原因,结合郑蒲港长江河段位置地形、水沙特性、风潮等特点,提出了顺应河势、疏浚引流等治理思路。马鞍山河段左汊动力轴线右偏、局部汊道分流调整是郑蒲港淤积的根本原因,牛屯河边滩上段冲刷、下段淤长下移是郑蒲港淤积的直接原因,应进一步增强心滩头部控导作用,提升整体河势稳定性,实施牛屯河边滩夹槽疏浚、滩尾斜向疏浚引流,并结合何黄汊动态监测和分析结果,适时开展以牛屯河边滩为重点的长江马鞍山河段综合治理。In recent years,the continuous sedimentation and elevation of the riverbed in the Zhengpu port basin of Maanshan have posed safety risks to production in the port area.To analyze the causes of sedimentation in Zhengpu port,this study,considering the location and topography of the Zhengpu port reach of the Yangtze River,as well as the characteristics of water and sediment,tides,and winds,proposes management strategies such as aligning with river flow trends and dredging for drainage.The results showed that the root causes of the sedimentation in Zhengpu port were the rightwing of the power axis of the left branch of Maanshan river and the diversion adjustment of the local branch.Therefore,it was necessary to strengthen the guiding role of the central beach head,improved the stability of the overall river regime,implement the Niutun river bank slot dredging,the beach tail inclined dredging drainage,combined with the dynamic monitoring and analysis results of the Hehuang branch,timely carry out the comprehensive management of the Yangtze river Maanshan river with the Niutun river bank as the focus.
