| 摘 要： | 采用一维数值解和二维解析解两种方法对某河段25km长区域的COD浓度进行现状模拟。主要结论为：两种方法对中山桥断面的水质模拟效果都不错，但两种方法又各有优缺点。一维数值解法求解过程是动态的，能更形象的模拟污染物浓度的迁移转化，但却损失了断面上的浓度变化细节。二维累积流量法对污染物浓度迁移转化的模拟精度大大高于一维模型，但求解过程是静态的，且需要的数据也多于一维模型。

| Abstract: | Use one-dimensional method and two-dimensional analytic solution to simulate COD for the area of 25 km.The main conclusions: Both of two methods have a good simu1ation solution,but each have merits and faults.One-dimensional numerical solution process is dynamic,which can simulate contaminations,transference more vivid,but neglect the detai1s of concentration variation on the section.Two-dimensional cumulated flow method has more exact stimulant precision,but the progress of solving is static,and this metho... |
