对雷州半岛西南部珊瑚岸礁区1995~1997年生长的造礁珊瑚Poriteslutea的骨骼密度、生长速度和δ18O分析表明:1)造礁珊瑚骨骼的密度、生长速度和δ18O与其生存环境的表层海水温度之间存在很好的相关性,高密度、低生长速率和高δ18O值对应于冬季;2)δ18O具有明显的年际和季节性变化。根据δ18O估计的表层海水温度变化范围与实测基本一致,进一步揭示了珊瑚骨骼δ18O可作为定量研究高分辨率表层海水温度变化的温度计。
The analysis of bone density, growth rate and δ18O of Coral reef Poriteslutea grown in the coral reefs southwest of Leizhou Peninsula during 1995-1997 showed that: 1) the density, growth rate and δ18O of coral reefs and the surface seawater temperature There is a good correlation between high density, low growth rate and high δ18O values corresponding to winter; 2) δ18O has obvious interannual and seasonal variations. According to δ18O estimated surface water temperature range and measured actually consistent, and further reveals the coral skeleton δ18O can be used as a quantitative study of high-resolution surface temperature of sea water thermometer.
