摘要
借助于灰色系统理论的思想和方法可以构造河流水质灰色模型，根据实测水质资料可以识别出河流水质灰色模型中的最优灰参数，在此基础上，可以对河流水质系统进行灰色模拟。灰色模拟考虑了实际河流水质系统中客观存在的不确知因素和偶然因素影响。本文概述了河流水质灰色模型的构造、河流水质灰色模型的研究意义、河流水质灰色模型的灰参数识别、河流水质系统的灰色模拟及其在四川沱江水质系统模拟中的应用。
The grey model for river water quality(GNIRWQ) can be developed using the grey system theory approach based the deterministic model,of which the optimal grey parameters can be estimated using the measured water quality data.The advantage of the grey modelling is that it can take the effects of many unknown and accidental factors in the river water quality system into consideration.This paper reports the significance about OMRWQ,the estimation of grey parameters in GMRWQ,the modelling based on GMRWQ and its application to the river water quality systm in Tuojiang River in China.
