| 摘 要： | 依据实测资料分析和数学模型计算分析了上游径流、外海潮流以及河势变化对长江口南支河段盐水入侵的，同时着重研究了长江口北支以及南支下游的南、北港三个盐水入侵源对南支河段盐水入侵的影响。研究表明：徐六泾水域基本不受盐水入侵的影响；浏河口以上主要为北支倒灌盐水所控制；钱泾、七丫口河段受北支倒灌的影响；宝钢水域受到三个人入侵源的共同影响，其含氯度峰值一般发生在中、小潮期，主要取决于北支倒灌南支的过境盐水。综

| Abstract: | Based on the observed data analysis and mathematical modeling,the effect of runoff,tide current and river regime change on the salt-water intrusion into the South Branch of the Yangtze Estuary has been studied.Meanwhile,the effect of the three salt-water intrusion sources of the North Branch of the estuary,South and North Channel at the downstream of the South Branch has been emphatically studied.The results show that there is little brine influence on the Reach of Xuliujing;the upstream reachfrom Liuhekou is mainly controlled by the brine intruded from the North Branch:the water area near the Baoshan Steel and Iron Complex is influenced by all of the three intrusion sources.The peak values of chlorinity usually appear in medium or small tidal period,depending on the brine from the North Branch.Af-ter considering the various factors,this paper suggests that the reach from Baoshan Steel and Iron Complex to Xuliujing in the South Branch be taken as the main reach for development and utilization of fresh water in the estuary.For the short term objective,it is suggested that the Chenhang bay reservoir and its inland reser-voir should be built to meet the fresh water requirment of Shanghai City in 2000. |
