摘要：

ENSO对我国海洋环境的影响大致可以归纳为以下四个方面。(1)ENSO期间我励沿岸水位出现较大偏低;(2)ENSO发生当年,全国登陆台风个数均少于常年,而翌年台风个数接近常年;(3)我国黄、东海及南海气旋发生频率与赤道太平洋表面温度和达尔文海海平面气压之间存在正相关;(4)ENSO发生当年,南海沿岸经流增大,气温,水温、盐度、PH值偏低,海水含氧最偏高,温、盐、密跃层强度增大,赤潮发生次数偏多,南海暖流和黑潮南海分支流轴的平均位置往南偏移。

The influence of ENSO on the marine environment of our country canbe included as the following four aspects: Lower water levels appeared inthe coasts during the period of ENSO; The number of landing typhoons inthe year of ENSO was less than those in the normal years, and the numberbecame normal in the next year; The frequencies of cyclones happened inthe Yellow Sea, East China Sea and South China Sea were closely relatedto the surface temperatures of the Tropical Pacific and the water level of Darwin Sea: During the year of ENSO, in the South China Sea coastalarea, the riyer runoff increased, the air and water temperatures, salinity and PH value became lower, the sea water oxygen content was higher, strong thermoclines, haloclines and pycnoclines appeared. the flow axis ofthe Warm Current and the Branch Current of Kuroshio in South China Seamoved to the most south of the surveyed area.
