| 摘 要： | 利用GRACE（gravity recovery and climate experiment）卫星重力、卫星测高和Ishii温盐度资料研究中国近海海平面变化。结果表明：1993-2014年南海海平面升高速率远高于同期全球速率，而黄海和东海均低于同期全球海平面上升速率。综合2003-2012年的上述3种数据，发现海水质量增加是导致渤海、黄海和东海海平面上升的主要原因，而南海主要受比容海平面上升影响。中国4个海域海平面年际变化均与ENSO有相关性，但是相关系数较小。4个海域在2000-2005年期间海平面均呈下降趋势，后来又慢慢回升。

| Abstract: | We study the sea level changes of China adjacent seas using satellite gravity data, satellite altimeter data, and thermohaline data. The results show that, compared with the global mean sea level rising rate during the period from 1993 to 2014, the sea level rising rate of the South China Sea is very fast, while the rates of the Yellow Sea and East China Sea are slow. The results and analysis based on these three kinds of data indicate that water mass change is the main reason for the sea level rising from 2003 to 2012, but the sea level of the South China Sea is mainly influenced by steric sea level change. The sea level interannual changes of the coastal waters of China have some correlations with ENSO, but the correlation coefficients are small. The sea level of China adjacent seas declined during the period from 2000 to 2005, and then rised again. |
