摘要： 本文根据吴淞、高桥的大量实测资料,分析了南港河段咸潮入侵的变化特性。利用长江大通站长系列的流量资料,采用流量机率推算水质机率。南港河段每年受到盐水入侵影响,但不同水文年入侵程度相差悬殊。

关键词: 南港河段, 氯化物, 盐水入侵强度

Abstract: Based upon a large amount of field data from the Wusong wakerworks and Gaoqiao Hydrographic Station,this paper analyses the characteristics of temporal and spatial variation of saltwater intrusion into the South Channel.Probabilities associated with different water qualities are calculated according to the probabilities of the corresponded fresh water discharges from the long records of the Datong Station.The water quality in the South Channel is affected by the saltwater intrusion each year,but the intensity varies greatly with different hydrologic years.

Key words: South Channel, Chlorinity, The intensity of saltwater intrusion
