摘　　要：某条河流除了河流自身的数量与质量特征外,该河流在河网结构中的空间位置及其相关结构特征将提供全局性的评价依据。河网的空间形态结构特征由各条河流的几何特征和河流之间的相互关系决定,为了完整表示河网的空间形态结构特征,本文提出了基于动态树结构的河网分析思想,阐述了动态河网树结构的建立、维护及其应用的方法。To decide the significance of a river apart from the quantity and quality of the river itself,the spatial position of it in the river network and its related structural characteristics will provide the overall evaluation basis.The spatial shape structural feature of the river network is formed by rivers' geometry characteristics and their correlations.In order to completely express the spatial shape structural feature of the river network,this paper proposes the analysis idea of the river network based on dynamic tree topology,expatiates the method of establishment,maintenance and application of the dynamic river network tree topology structure.
