| 摘 要： | 长江和畅洲段河床演变造成南汊分流比逐年下降，本文对不同分流比情况下的污染带分布和断面平均深度进行了计算，其结果表明：随着分流比的下降，南汊水体的环境容量减少，水质污染加剧，从水体环境保护方面定量论证该江段河道整治工程的重要性。

| Abstract: | The discharge ratio of the southern branch of the Yangtze River in He Chang Zhou section is decreasing gradually due to the evolution of river channel. The calculation results of pollution zone distribution and sectional average of pollution density for various disscharge ratio show that, following the decrease of the discharge ratio the environmental capacity of the southern branch will be weakened and water pollution will be getting worse. Thus the importance of the channel control project has been demonstrated. |
