全面回顾了全新世中期以来几十年来南海海平面变化的研究，重点讨论了一些争议和热点问题，结论表明，全新世中期高海平面在7.0~5.5 kaBP期间最高达到现今平均海平面2~3 m，随后海平面发生振荡并下降至现今平均海平面，在一定程度上与全新世温度位相一致，表明它们的接近程度。通过卫星高度计和潮汐计观测得出的现代南海海平面上升速率分别达到3.9和2.4毫米/年，均略高于同期全球平均速率。此外，还列出了海平面研究的一些不足和问题，初步得出改进措施包括：（1）采用更精确的测年技术，尽量减少误差；（2）开展构造稳定研究（3）采用更精确的海平面指标，例如微环礁和管虫结壳。
The researches on sea-level changes in South China Sea since mid-Holocene during the past several decades have been comprehensively reviewed.Some disputes and hot questions are mainly discussed and the conclusions indicate that high sea level in mid-Holocene reached maximally 2~3 m above present mean sea level during 7.0~5.5 kaBP,and the following sea level performed oscillating and fell to present mean sea level,in phase of the Holocene temperature to some extent,suggesting their close relationship.The modern rising rates of sea level in South China Sea resulting from observation of satellite altimeters and tide gauges,are up to 3.9 and 2.4 mm/a respectively,both slightly higher than the corresponding contemporaneous global mean rates.Additionally,some shortages and problems about sea-level researches are listed,and preliminary improving measures concluded include:(1)using more precise dating technology to minimize errors;(2)carrying out researches on tectonically stable locations;(3)adopting more precise sea-level indicators such as microatolls and tubeworm encrustations.
