| 摘 要： | 在简要介绍了系统模型基本原理以及率定参数方法的基础上，选择沙市、螺山、汉口3个长江干流控制断面和主要支流控制站的历史实测资料，应用多输入单输出系统模型模拟预报长江洪水过程，选取发生大洪水的1981，1982，1983，1995年和1996年汛期资料作为率定期资料，以1998年资料作为检验期资料，计算结果得到了较高的精度，模型效率系数超过97％，洪量相对误差小于1．5％。

| Abstract: | This paper introduces the fundamental principle and parameter rating method of multiple input and single output system model for simulating flood forecast.The historic measured data from 3 hydrologic basic stations of Shashi,Luoshan and Hankou on main stem of Yangtze and major hydrologic basic stations on tributaries are selected for flood simulation analysis.The model is applied to simulate the Yangtze flood.The flood season data of major flood years 1981,1982,1983,1995 and 1996 are selected as rating data,and the data of 1998 is selected for checking.The computational results are satisfactory with high accuracy.The model efficiency coefficient is over 97%,while the relative error of flood volume is less than 1.5%. |
