摘要：Based on the grey theory, grey characters of river environment system were analyzed. The velocity anddispersion coefficient and attenuation in river were considered as uncertainty parameters and expressed asgrey parameters. A grey differential equation of contaminant diffusion in river was built. And the equation hasspecial structure. The truncation error of finite differential method in solving the model was corrected. Accordingto the model, distribution values of pollutant concentration under sudden pollutant discharge can be obtaineddirectly, which can provide abundant and useful water quality information for the plan and control of waterpollution. It is shown that the calculated results obtained from the grey model are reliable and reasonable.
