海南近海海域浊度与悬浮颗粒物粒径的分布特征

Characteristics of turbidity and suspended particle size distribution on adjacent area of Hainan

利用2005年8-9月在海南西部近海海域底质调查获得的水体浊度、悬浮颗粒物粒径的数据和资料,探讨了该区浊度和悬浮颗粒物粒径的分布规律,结果表明:(1)研究区表层水体浊度与悬浮颗粒物的总体积浓度由岸向外海方向逐渐减小,底部水体浊度与悬浮颗粒物的体积浓度高值区呈斑状分布;(2)研究区的水体浊度和悬浮颗粒物体积浓度随着水深增大而增大,部分调查站位出现异常现象;(3)研究区表层和底部水体浊度与悬浮颗粒物各粒级的体积浓度相关性较好,相关系数在0.85以上。

Based on the investigation data of turbidity and suspended particle size distribution on western adjacent area sea, the characters of turbidity and suspended particle size distribution have been studied, There are three points in this paper. Firstly, the turbidity and the volume concentration will increase as the water deepens. Secondly, The turbidity and the total volume concentration of suspended particle in surface are decreasing as away from the shore. But the turbidity and the total volume concentration of suspended particle on bottom are high in several area. Thirdly, the corresponding relationship between turbidity and the volume concentration of every size suspended particle is good, and the value of the relationship coefficient is more than 0. 85.
