| 摘 要： | 通过对浊漳河流域 1996～ 2 0 0 0年 2 1个监测断面的枯水期 (5月 )、丰水期 (8月 )和平水期 (10月 )地表水采样分析 ,研究了其中主要污染物COD、BOD5、NH3 N、NO2 N和挥发酚的时空变化特征。结果表明 ,污染物浓度随季节变化特征较为复杂 ,但总体表现了枯水期 >平水期 >丰水期的总体特征。污染物沿程变化与各断面接纳不同来源的污染物有关。

| 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,BOD 5,NH 3-N,NO 2-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. |

| Keywords: | Zhuozhang river basin pollutant comprehensive pollution index temporal-spatial change. |
