摘　　要：建立了黄河口海域化学需氧量(COD)输移扩散数值模型,以COD为例研究了潮流-径流耦合作用对黄河入海污染物输移扩散的影响规律。研究发现在入海通量一定的前提下,COD沿程衰减速度随着径流量的增加而降低,沿正北方向衰减速度最大,并给出了径流对COD扩散影响范围,可供黄河口海域污染物扩散的研究及周边海域的环境保护工作借鉴。A numerical model of Chemical oxygen demand(COD)transport and diffusion in the Yellow River Estuary is established to study the effect of tidal flow-runoff coupling on the transport and diffusion of pollutants discharging by Yellow River.It is found that with the increasing of discharge,the reducing velocity of COD decreases along the way,and the reducing velocity of true north is the largest.The influence range of runoff on COD diffusion is also given.This paper can be used as a reference for the study of pollutant diffusion in Yellow River Estuary and environmental protection in the surrounding waters.
