利用等离子体质谱技术分析了取自海南岛南部沿岸的现代滨珊瑚高分辨率的Ba／Ca比值。结果表明，该珊瑚的Ba／Ca比值具有明显的双峰态的季节变化，其中春季和秋季Ba／Ca比值较高，而冬、夏两季则较低。海南岛南部及邻近地区季节降雨的变化所控制的陆源Ba输入是这些珊瑚Ba／Ca比值变化的重要控制因素，而该区夏季相对较高的表层海水生产力可能也对其有重要影响。
High-resolution Ba / Ca ratios of modern shore corals taken from the southern coast of Hainan Island were analyzed using plasma mass spectrometry. The results show that the Ba / Ca ratio of the coral has obvious bimodal seasonal changes, of which the Ba / Ca ratio is higher in spring and autumn than in winter and summer. The input of terrestrial Ba controlled by seasonal rainfall in the southern Hainan Island and adjacent areas is an important controlling factor for the change of Ba / Ca ratio in these corals, and the relatively high surface water productivity of summer in this area may also have a significant impact on it.
