| 摘要: |
| 用国家海洋局1975—1982年间在黄东海调查的海水透明度数据换算为悬浮体含量,用NOAA卫星高分辨率辐射计数据计算悬浮体含量,以绘制悬浮体含量分布图。分布图显示,研究区有三个悬浮体含量高值区,位于苏北浅滩、长江口、成山角沿岸水域。研究表明,风浪是影响悬浮体含量的海洋外部的主要因素。层化参量是影响悬浮体含量海洋内部的主要因素。 |

| Abstract: |
| The seawater transparency map and water color map were drawn with the measured data obtained in the Yellow Sea and the East China Sea in 1975 - 1982. The relationship between the transparency of seawater and the suspended matter content in seawater was reduced. The suspended matter contents were calculated with the transparency of seawater and used to draw the suspended matter content map.
The governing equation for the relation between NOAA satellite data and suspended matter content in seawater was established. The suspended matter contents in the Yellow Sea and the East China Sea were calculated with NOAA satellite data. NOAA satellite image coded with different colors were drawn to show suspended matter contents distributed in the Yellow Sea and the East China Sea.
Fig.4, 5, 6 show there are three high value suspended matter content regions: the shallows of northern Jiangsu Province, the estuary of the Chingjiang River, the coastal water region of Chengshanjian.
In the shallows of northern Jiangsu Province, the suspended matter content is always high in a year. In winter, the turbid water distributes and disperses eastwards to a wide area. In summer, the area of the turbid water is comparatively smaller. |
