归纳总结了长江马鞍山河段基本情况、近期河道演变特点和河道治理概况；根据现有河势条件及近年崩岸险情，分析指出了目前本河段存在的主要问题；结合河道治理规划情况，探讨了下一步河道治理措施。研究认为：河势调整工程是该河段整治的关键，重点是通过数学模型和河工模型试验研究提出河势调整工程方案；主要是在左岸新河口一带布置导流工程和上下何家洲及心滩串沟封堵并岸工程，并辅以江心洲尾的何家洲尾挖槽工程。鉴于整治工程的紧迫性和时效性，建议相关部门尽快开展相关前期工作，为整治工程早日实施创造条件，进而实现该河段河势的稳定。

The basic information of Ma’anshan reach of Yangtze River and  its short-term river evolution characteristics and the existing river regulation projects are summarized. Based on the current river regime and the bank collapse in recent years, major problems in the river reach are pointed out, and river regulation measures to be taken in the next stage are discussed in light of the river regulation planning. Research results show that the river regime adjustment projects are key points for the river regulation, and the top priority is to bring forward specific engineering schemes through mathematical modeling and physical modeling tests. It’s suggested that diversion works around Xinhekou on the left bank, and  plugging works in the string trench between the upper and lower Hejiazhou and Xintan sandbars should be taken as main schemes, with chamfering projects at the tail of Jiangxinzhou sandbar as auxiliary works. Due to the urgency and effectiveness of these works, it is strongly suggested that relevant government agencies should conduct preliminary works as soon as possible to help implement the regulation projects at an early date to stabilize the river channel.
