由于海平面上升在地理上并不均匀，而是表现出很大的区域差异，使用石英作为天然剂量计的光学模拟发光已被证明是一种强大而可靠的测年技术，以确定世界各地年轻的沿海沉积物的沉积年龄。对采自海南岛沿海一个海滩海岭和两个阶地的样品进行光释光测年，研究海平面的变化。结果显示：（1）海南岛海岸砂在沉积前已被漂白，石英光释光可测得小于200年的海岸沉积物，是古相对海平面高水位记录的良好指标之一;（2）高出现今海平面4 m、3.7m和2 m的3种海岸沉积物分别沉积于2.40 ± 0.05ka、2.92 ± 0.17ka和4.26 ± 0.10ka，（3）与南海热带气旋观测资料的对比表明，海南岛晚全新世海岸沉积物可能受到了热带气旋的改造。
Since the sea-level rise is not geographically homogeneous but rather shows great regional differences, optically simulated luminescence using quartz as a natural dosimeter has proved to be a powerful and reliable dating technique to determine depositional ages of young coastal sediments around the world. The samples acquired from one beach ridge and two marine terraces in coastal Hainan Island, southern China are detected OSL dating for the investigation of sea-level changes. The results show: (1) coastal sands in Hainan Island were well bleached before deposition, and the quartz OSL can date coastal sediments younger than 200 years, which could be one of good indicators for paleo relative sea-level highstand records; (2) three coastal sediments with 4 m, 3.7 m, and 2 m higher than present sea-level were deposited at 2.40 ± 0.05 ka, 2.92 ± 0.17 ka, and 4.26 ± 0.10 ka, respectively, which indicate that the height of highstand relative sea-level are higher than both mean global sea-level eustacy and those records offshore southern China; (3) Comparisons with tropical cyclones observations around South China Sea indicates that the late Holocene coastal sediments of Hainan Island might have been reformed by tropical cyclones with a highstand sea-level.
