| 摘 要： | 分析了两种类型河流COD污染通量变化特征。汇水面积较大的河流 ,下游断面汛期COD通量远大于点源COD入河排污量 ,典型河流断面可达其 9～ 2 2倍。这类河流COD污染通量与河水流量呈显著正相关 ,r值在 0 .90 3～ 0 .997范围 ,文中给出线性回归方程。河流点源污染量变异系数一般在 30 %～ 6 0 %,面源可达 12 7%～ 2 0 7%。

| Abstract: | The variation characteristic of COD Loading in two types of rivers were revealed. COD loading of the river with large basin were more larger than drainage came from points pollution resources, it would be {9-22times}. The coefficients of variation of drainage came from points pollution resources were30-60%, and {127-207%} came from surface pollution resources. The COD loading and water rate of flow especially had positive relations. The range of r were 0.903-0.997.The regression equations were given. |
