Using precise elevation measurements and precision TIMS U-series dating methods, the eastern part of Hainan Island at low tide near Qionghai Qing Ge original death exposed outer reef corals and live micro-atoll aerodromes be investigated. Survey results show that Qing Ge and near aerodromes micro atoll reef growth and limit the presence of a narrow (± 8 cm), located at the lowest ebb surface, is quite accurate sea level markers. former life and death of coral near the top surface of the top modern living micro-atoll surface elevation data and accurate and reliable data TIMS U-series ages, 5 500 ~ 5 200 aBP (U / Th age, compared to 2008) above sea level at least for now (100 ± 8) cm, real sea plane is likely higher than now 2.0 ~ 2.2 m. Overall, sea level fluctuations 5 500 ~ 3 500 aBP period, the volatility of about 0.6 m, and this volatility and climate fluctuations have a better correspondence .4 400 ~ During the development of the missing 3 900 aBP Qionghai reefs are likely related to the dry and cold weather at this time.
