南海现代海平面变化研究的进展

Advance of research on recent sea level changes in South China Sea

本文根据笔者近年对广东海平面变化的研究,并参考前人的研究结果,对南海现代海平面研究的进展进行了较系统的评述.认为数十年来南海相对海平面总体上呈上升趋势,上升速率一般小于2.5mm/a.1.8mm/a或1.9mm/a可以近似地作为绝对海平面上升速率.预测2030年或2025年相对海平面上升幅度为20～25cm.

According to our recent research on the sea level changes inGuangdongProvince and referring to the previous studied results,the advances of recent sea level change research in the South China Sea were reviewed systematically.Itis considered that the general trend of relative sea level change was rising inthe South China Sea during the past several decade.The rising rate is generallyless than 2.5mm/a.The rising rate of absolute sea level was 1.8mm/a or 1.9mm/a approximately.It is forecasted that the relative sea level may in an amplitude of20～25cm until 2030 or 2025.
