摘　　要：根据历史资料和35年的水下地形测量资料,对江西九江长江中张家洲的形成、演化和发展进行分析。其形成最早以小洲为支点,以长条形滨河床砂坝堆积的形式向北东方向逐步生长。其形成动力学因素主要受岸带的边界条件和河流水动力条件的制约。张家洲的生长发育对地区防洪安全产生重要影响,治理本地区水患因遵循河流体系演化的自然规律。The formation and evolution and development of Zhangjiazhou continent in Changjiang rive are analyzed according to historical data and topographic survey data of underground water in 35 years in Jiujiang,Jiangxi Province. The eariest small continent was formed as a pivot,which developed progressively toward northeast in the form of long-strip sand dam of river bed accumulation. The forming dynamics factors are restricted mainly by border condition of bank and water dynamic water flow of river. Development of Zhangjiazhou continent would have important influence on the flood protection,and flood administration should abide by natural rules of evolution of fluvial system in this region.
