摘　　要：讨论了河网概化的一般原则,并在分析单一河段水流数学模型的基础上,建立了可以适用于一般河网体系水流数值计算的数学模型,并采用荆江—洞庭湖的相关资料进行了验证。结果表明,模型的计算值与实测值吻合较好,说明该模型具有较好的适用性。In this paper a normal principle of the river system is introduced. Based on the analysis of watersediment model of single reach, a numerical model for calculation of normal river system is established and tested with the observed data of the Jingjiang River and the Dongting Lake The result shows that the computed data and the observed data fits well, which indicates that it is suitable to describe the complex boundary of the JingjiangDongting,and the model is applicable.
