摘要: 利用卫星测高和验潮站资料计算分析了越南近海海平面变化。结果表明,两种数据得到的海平面变化过程具有很好的同步性,其中,由测高数据计算得到的1993-2015年越南近海整体上升速率为3.18 mm/a,沿岸验潮站海平面上升速率为4.1 mm/a。在整个验潮站观测时段,越南沿海海平面呈上升趋势,平均上升速率为3.02 mm/a。越南近海海平面表现为较强的季节性特征,在红河和湄公河三角洲沿岸地区,极易受到风暴潮和洪水等季节性气候的影响。

Abstract: Sea level changes along the coast of Vietnam were calculated and analyzed by using satellite altimetry and tide gauge data. The results showed that there is a strong correlation between sea level changes obtained from the both data. The rate of rising sea level in Vietnam calculated by the altimeter data from 1993 to 2015 was 3.18 mm/a, and the rate by tide gauge data was 4.1 mm/a. During the whole time span of tide gauge observation, the coastal sea level of Vietnam was on the rise, at a mean rate of about 3.02 mm/a. The coastal sea level of Vietnam was characterized by strong seasonal characteristics. In the coastal areas of the Red River and the Mekong Delta, it was highly susceptible to the seasonal storms and floods.

Key words: tide gauge, satellite altimetry, coast of Vietnam, sea level change
