摘要
分析了树状河流的空间特征,利用了水系的主支流交汇点作为图的节点,河段作为图的边,水系的流向作为有向图的方向,实现了树状河流空间关系的表达。
Represent of spatial relation is the basis of spatial analysis of geographical special element. Taking tree-like river as an example, we used the theory of graph crossing point of main-secondary reach as node of graph channel as border of graph, and direction of river as direction of oriented graph, represented complex river network with oriented graph, and spatial relation of tree-like river with graph.
