从西沙和海南岛南部海区钻取的5个滨珊瑚(Porites)岩芯,研究其逐年生长率变化及与海面温度(SST)关系,得出近百年来研究海区的滨珊瑚生长率平均为11mm/a,变化于7～15mm/a之间,珊瑚生长率与SST呈显著正相关.据1961～1993年的资料统计,各个样品的相关系数在0.77～0.89之间,从而建立了珊瑚生长率温度计.由它后报1993～1961年间该海区的SST,误差为土0.12～±0.17℃.由后报得出近百年来南海北部热带海区的SST上升率为0.20℃/100a,明显高于中国气温的0.09℃/100a,但低于全球温度和西太平洋热带海区SST的上升率.
Five peritoneal cores drilled from the sea areas of Xisha and South Hainan Island were used to study the relationship between their annual growth rate and sea surface temperature (SST). The average growth rate of coral in the study area over the past 100 years was 11 mm / a, the variation was between 7 and 15 mm / a, and the coral growth rate was positively correlated with SST.According to the data from 1961 to 1993, the correlation coefficient of each sample was between 0.77 and 0.89, thus establishing the coral growth rate The SST of this sea area was reported from 1993 to 1961, with an error of 0.12 ± 0.17 ° C. After reporting, the SST rising rate in the northern South China Sea in the past 100 years was 0.20 ℃ / 100a, which was significantly higher than that of China The temperature is 0.09 ℃ / 100a, but lower than the global temperature and the rising rate of SST in the tropical Pacific Ocean.
