摘　　要：从长江荆江分流河的河道平面形态及其近百年来的演变特征、河道比降、河道沉积特征、地质背景和地貌特征等方面进行了论述，认为这些河道是一个统一的网状河流体系。对各主要河道的输水输沙特征及其演变趋势和洪水灾害特征进行了讨论，结合网状河流系的基本特征，提出了洪灾防治的主要措施。In this paper the geological background, geomorphological characteristics and channel evolution of Jingjiang Tributary in the past 100 years are discussed. The channel stability and gradient and sedimentation rate of Jingjiang Tributary show characters of anastomosing river sys tem. The runoff and sediment transportation of the tributaries and representative aspects of flood calamity are also discussed. The ways of controlling flood are put forward according to the characteristics of Jingjiang anastomosing river and characteristics of flood calamity.
