| 摘 要： | 城市雨水地表径流模型的目的是推求城市雨水地表径流的流量过程线，从而模拟雨水的地表径流过程。瞬时单位线法是解决模型的一种方法。由瞬时单位线推求S曲线和时段单位线，可以得到城市雨水口径流的流量过程线。瞬时单位线是该过程的基础，求解瞬时单位线参数N和K值是十分重要的。与过去用矩法求解这两个参数比较，介绍了用遗传算法来推求瞬时单位线参数的方法和过程，并验证了遗传算法推求参数的可行性和可信性。

| Abstract: | The purpose of the city storm surface runoff model is to draw the surf ace runoff hydrograph and simulate the process of storm runoff. Instantaneous un it hydrograph is one of the methods to solve the model. S curve, time unit hydro graph and surface runoff hydrograph can be gotten through instantaneous unit hyd rograph. Comparing with matrix method, the article introduces to use genetic alg orithm to calculate parameters N and K, which are very important in the process of solving instantaneous unit hydrograph. The article also testifies the feasibi lity and creditability of using genetic algorithm to calculate the parameters. |
