摘　　要：黑沙洲河段是典型宽窄相间的长江平面河道形态,其江洲众多,左右汊分流比波动较大,深泓线左右摆动,发育形成多分汊型河道,对河道内崩岸区影响较大。定期对河道进行地形测量、水文断面及水流分沙资料收集、分析,充分掌握河床动态变化情况,对分析崩岸区岸线稳定,为河道管理部门提供崩岸区治理提供科学依据。Heishazhou Reach is a typical flat channel form of the Yangtze River with wide and narrow phases.There are many rivers and continents with large fluctuation of left-right branching ratio and oscillation of the deepeave line.Multi-branching river is developed,which has a great influence on the bank collapse area in the river.Regular topographic measurements,hydrological sections and data collection and analysis of flow and sediment distribution of rivers can fully grasp the dynamic changes of riverbed,and provide scientific basis for analyzing the stability of bank collapse area and providing river management departments with treatment of bank collapse area.
