摘要
根据6个沉积柱样的^(14)C测年分析、^(210)Pb分析资料,以及1987 ～1996年间4期实测港区海底地形图对比分析结果,揭示了近百年来三亚港淤积速率明显增强的趋势。进一步的分析研究表明.造成这种趋势的主要原因是近期人类活动导致三亚港泻湖纳潮量减少、人港泥沙来源增加.以及随意穿越主航道的船只大量增加等。
The siltation rates of Sanya Harbour have been increasing remarkably during the last 100 years, according to the results of 14C analysis and 210Pb analysis on samples of 6 depositional columns, together with the results of comparison between various seafloor topographic maps surveyed from 1987 to 1996. Further research shows that, it is the increasing human activities that reduse the tidal prism, increase the sediment sources, and cause more and more vessels to cross the main channel of Sanya Harbour.
