通过两个航次的出海,对珠江口广大海区悬浮颗粒物质的来源、含量、分布、迁移和扩散机制进行了系统性研究。结果表明,研究海区的悬浮颗粒物质有明显的时间和空间变化,一般来说,丰水期的含量高于枯水期的含量,底层水的含量高于表层水的含量,近海岸的含量高于远离海岸的含量,风浪大时含量亦增加,研究海区的悬浮颗粒物质主要来自珠江流域,文中详细讨论这种物质的迁移以及影响迁移和变化的各种机制。
Through the two voyages to the sea, the source, content, distribution, migration and diffusion mechanism of suspended particulate matter in the vast Pearl River Estuary were systematically studied. The results show that there is obvious time and space variation in the suspended particulate matter in the study area. Generally speaking, the content in the wet season is higher than that in the dry season, the content of the bottom water is higher than the surface water, and the content of the near shore is higher than the distance The content of seabed and the content of wind and waves are also increasing. The suspended particulate matter in the study area mainly comes from the Pearl River Basin. The article discusses in detail the migration of this material and the various mechanisms that affect the migration and change.
