海南岛滨珊瑚δ^18 O对环境条件的响应

Based on the determination of the oxygen isotopic analysis of the skeleton of living Porites lutea in Shalao fringing reef, Hainan Island, we' obtained a coral δ^18 O record for an 11 year period(1992-2002). We have assessed the characteristics of coral δ^18 O signals responding to environmental conditions by comparing coralδ^18 O variation with a local record of sea surface temperature (SST) and sea surface salinity (SSS), respectively. We conclude from our comparison that the annual variation ofδ^18 O is controlled by SST, whereas the seasonal variation of it by SSS.
