| 摘 要： | Porites coral in the nearshore waters off Hainan Island can give off yellowish-green fluorescence under UV laser induction.After fitting the data between rainfall and fluorescent intensity,it can be found that both appear in a simply linear equation with a correlation coefficeient of 0.78.The model equation can be used to reconstruct the rainfall in the past time by means of the determined fluorescent intensity.The correlation diagram of the determined and calculated or hindcast rainfall shows a synchronous change from 1982 to 1997.The peak positions of the variant curve are usually related to the El‘nino year.That means the drought and flood recycles are restrained to some extent by globally environmental changes.Therefore,the coral fluorescent intensity acts as a geochemical proxy for reconstructing the rainfall series in the past hundreds of years and predicting the drought-flood variant tendency in the future time.

| Abstract: | Porites coral in the nearshore waters off Hainan Island can give off yellowish-green fluorescence under UV laser induction. After fitting the data between rainfall and fluorescent intensity, it can be found that both appear in a simply linear equation with a correlation coefficient of 0.78. The model equation can be used to reconstruct the rainfall in the past time by means of the determined fluorescent intensity. The correlation diagram of the determined and calculated or hindcast rainfall shows a synchronous change from 1982 to 1997. The peak positions of the variant curve are usually related to the El’nino year. That means the drought and flood recycles are restrained to some extent by globally environmental changes. Therefore, the coral fluorescent intensity acts as a geochemical proxy for reconstructing the rainfall series in the past hundreds of years and predicting the drought-flood variant tendency in the future time. |
