由河流流速、COD浓度估计河流COD衰减系数的经验模型

An Estimation Model of River COD Degradation Coefficient from River Velocity and COD Density.

本文在综合分析影响河流ＣＯＤ衰减系数的各要素和系统调查相关资料的基础上，采用逐步回归分析方法得到了一个由河流流速、ＣＯＤ浓度估计河流ＣＯＤ衰减系数的经验模型，并通过方差分析检验了模型的可靠性。该经验模型简便，易于操作，既可应用于现有的河流水体，也可与水质模型相结合应用于变化后的河流水体，具有较强的应用性。

Based on the analysis of the factors affecting river COD degradation coefficient and the systematic data investigation,an estimation model of river COD degradation coefficient from river velocity and COD density has been developed by progressive regression analysis method in this paper.The model reliability has been demonstracted by variance analysis.The model is simple and easy to control,and can be applied in both present river water and future changed river water,so it is applicable.
