中文摘要:
      根据对近年调查资料的分析,本文试就长江径流变化对邻近海区理化环境的影响、对河口及邻近海区的浮游动物的数量分布以及渔业的影响等方面进行了讨论.长江径流的变化关系到邻近海区温、盐度和冲淡水的分布,并且存在着较强的相关;不少经济鱼类的渔场正位于浮游动物总生物量高区,而近海浮游动物总生物量与长江径流量之间有着显著的正相关关系;径流量的变化不仅改变渔场位置,而且影响海区渔获量的变化。文中着重讨论了长江口、舟山和鱼山渔场的带鱼、鲐鲹鱼的分布;渔场形成,渔获量的大小与径流量关系.
英文摘要:
      Tha analyses of the data collected in recent years, together with the invdstigation results from some fisheries research organisations in the past,have shown that the fluctuations of the annual runoff of Changjiang River mostly and directly affect on the temperature, salinity and the distribution of the diluted water in the Changjiang Estuary and its ad jacent sea areas.The outstanding correlations between Changjiang River runoff and the magnitude areas And their distributions of zooplankton bionzass in the coastal waters, the positrons of the commercially important fishing grounds, and the catches of same important commercial fishes have been found also. Some historical facts in the fisheries of hairtail, Ohub mackerel and scads in tha ChangJiang Estuary, Zhoushan anal Yushan Tishing Grounds are to be used to illustrate the phenomena mentioned above.
