摘要
本文基于空间离散化理论与方法和DEM技术,将城市地表划分成一系列网格单元,从水平方向和垂直方向研究城市地表空间位置和综合因素的空间离散化描述、表达以及参数模型化处理机制,创新构建出一个特定的以DEM空间离散化解析函数式表达的、综合顾及城市地表地形特征、下垫面物质形态和人工建筑物等因素的地表产流和汇流模型,实施城市地表产流和汇流的路径以及水流累积量的分析计算。
This paper divided city ground into grid cells based on spatial discretization theory and methods and DEM technology, and studied on the description and expression of spatial discretization and parameter model on spatial location and general factor from level and uprightness directions. It founded the model on urban surface runoff considering the topographic characters, underground mat- ters and artificial buildings based on the expression of I）EM spatial discretization functions, in order to realize the analytical calculation of path and stream cumulative capacity on urban surface runoff.
