| 摘 要： | 使用1980—2010年的水位、气温、海温、气压和风场资料,对中国渤黄海沿海2月份的海平面变化特征以及异常偏高成因进行了探讨,分析结果表明:近30年,渤黄海沿海2月份海平面呈现明显的上升趋势,2009年和2010年2月份的海平面达到近30年的高值,冬季高海平面导致全年平均海平面偏高。近两年2月份海平面处于多个长周期振动的高位重合期,各振幅叠加的结果近100 mm,对海平面起了明显的抬升作用。高海平面使得辽宁、河北以及山东等沿岸地区的海水入侵距离和土壤盐渍化程度均有所增加,海岸侵蚀加重;上海在2009—2010年连续2年2月份发生了近年较严重的咸潮入侵。2009年和2010年2月份,气压较常年同期显著偏低,冬季季风显著偏弱,是海平面上升的主要原因之一。 |

| Abstract: | The research results showed that in recent 30 years,monthly mean sea level during nearly two years reached the highest in the coastal region of Bohai Sea and Yellow Sea in February,and the higher sea level in winter caused the higher yearly sea level.In recent 30 years,the monthly mean sea level was increasing obviously along the coast of Bohai Sea and Yellow Sea in February,reaching its highest level for the two consecutive years of 2009 and 2010.The coincidence of several long-period vibration made the sea level high during 2009—2010.The high sea level made the sea water intrusion and the salinization of the soil increase in Hebei,Shandong and other coastal areas and,intensified the coastal erosion.Salt tide occurred seriously in Shanghai during the two consecutive years of 2009 and 2010.In nearly two years of 2009 and 2010,air pressure was significantly lower than those in the constant years,and winter monsoon was obviously weak,which were the main reasons for sea level rise. |
