Abstract: Sampling from 21 monitoring sites in low-flow period (May),high-flow period (August) and mean-flow period (October) from 1996 to 2000,the temporal-spatial change characteristics of main pollutants (COD,BOD5,NH3-N,NO2-N and volatile hydroxybenzene) in the surface water of Zhuozhang river were studied.The results showed that seasonal change of pollutant concentration was relatively diversified.Order of these change characteristics was: low-flow period > mean-flow period > high-flow period.The change characteristics of main pollutants along the river was mainly related to the difference of source pollutants.
