本文将控制论中差分模型识别方法,与J·C·I·杜格教授介绍的响应函数模型识别方法作了比较,建立了响应函数与差分方程系数互相转换的关系方程.这个模型的差分方程,似可看作水文学上多种线性概念性汇流模型在离散情况下的数学通式,成为确定某些概念性模型参数的工具.文中设计的计算机程序经20余次洪水检验,得到初步成功.此法具有计算精度较高,可用于水位预报,便于实现实时联机修正预报等优点,是一种值得注意的汇流计算的黑箱子方法.
In this paper, we compared the difference model identification method in cybernetics with the response function model recognition method introduced by Professor J.C.D.Duger and established the relational equation between the response function and the differential equation coefficient conversion. The difference equation , Which can be regarded as a mathematical general formula for discrete conceptual linear models of confluence in hydrology and become a tool for determining some conceptual model parameters.The computer program designed in this paper has been initially tested successfully with more than 20 flood tests This method has many merits, such as high computational accuracy, which can be used for forecasting water level and facilitating real - time on - line forecasting. It is a notable black box method for confluence calculation.
