摘要: 南港河道水域宽广,水体量大,动力条件强,悬沙含量较高且都是细颗粒物质,纳污容量大,具有较强的输运、稀释和自净能力。污水进入南港以后,污染物在河道中迁移转化,主要吸附在泥沙上。在外泄过程中污染物质在南港中往返逗留,循环输移,向底层、滩地、涨潮沟等地迁移,并在河海相接地带富集。

Abstract: The water area of the South Channel is wide,the volume of the water body is large,thedynamics is strong,and the content of suspended sediments is higher.the sediments consist of fine-grained sediments mostly.The water has high capability of transporting,diluting and clearin.The pollutants of the South Channel are absorded mainly by sediments.They go there and back during empting to the sea.They are circularly transported and transported towards bottom,flats,flood channels,and accumulated at the places between the river and the sea.

Key words: South channel of the Changjiang estuary, Hydrology and sediment, Pollutant transport
