市区性河流水质数学模型研究

STUDY ON EVALUATING THE WATER QUALITY CONDITION WITH THE TWO MODES OF BLURRED DEGREE OF APPROXIMATION AND THE ASSEMBLED ANALYSIS

本文通过对哈尔滨信义沟的调查和分析，研究了市区性河流的自净规律，将高浓度悬浮物沉降和有机物厌氧分解纳入河流水质模型，从而得出了广义的市区性河流多河段水质数学模型，这种建模的方法对市区性河流具有普遍的意义．

This paper evaluated the annual monitoring average value of eleven rivers with the two modes of the blurred degree of approximation and the assembled analysis,analysed the shortcoming of the two modes. The results of handling the assembled analysis of the degree of approximation moment with the normalization and unnormalization methods are also compared. Finally,the authors put forward a method of the assembled analysis of the degree of approximation moment with the relevan parameters of the environmental unit and the water quality standard unit.
