| 摘 要： | 2005年8月到10月国家海洋局第二海洋研究所在海南岛周围进行了近海底质和悬浮体的调查。利用悬浮体调查数据对比了海南岛东西两侧陆架悬浮体浓度的分布特征,并探讨影响其分布的因素。研究结果表明,海南岛东西两侧陆架的悬浮体在垂向上的分布形式基本有3种:增加型、C型和稳定型。海南岛东西侧陆架在悬浮体浓度分布方面存在较大差异,自然条件是造成这种差异的主要因素。物质来源对悬浮体体积浓度分布也有较大影响。悬浮体体积浓度在局部的高值、高梯度区与流系(如暖涡和上升流)有较为密切的关系。在东侧陆架,盐度分布与悬浮体的浓度分布有一定的关系。

| Abstract: | The Second Institute of Oceanography of SOA has done the researches on the bottom substances and suspended particles around Hainan Island from August to October 2005. According to the research data, the distribution of the suspended particle has been studied in the east and west continental shelf, and the influence factors have also been discussed. The result shows that there are three types of the distribution of suspended particles: increasing type, C type and steady type. There exist differences between the east and west continental shelf, and the natural environments are the main causes of the differences. The material sources have also affected the distribution of suspended particles. The high concentration of the suspended particles and high gradient of the distribution have a close relationship with the currents. On the east continental shelf, the distribution of salinity consists with the suspended particles. |
