摘要
作为ＧＩＳ新技术，动态分段可以有效地实现河流一维水质扩散的模拟和空间显示分析。该文给出了动态分段数据库设计的基本思路、河流一维水质模型的功能设计及整个模拟系统的结构流程。
As a new GIS thchnique,dynamic segmentation can be effectively applied to perform one-dimensional river water quality dispersion simulation and spatial display and analysis.The basic idea of dynamic segmentation database design was described,and the functional design of exact one-dimensional river water quality dispersion model as well as the structural flow chart of the overall simulation system was given.
