摘要：

通过滨州港所在海域的卫星遥感图像分析,揭示了在不同条件下海域的含沙量分布特征和泥沙的运动规律,并对其形成的原因进行了初步的分析。结果表明,滨州港海域的含沙量总体是比较高的,近岸区比邻近的黄骅港海域含沙量还要高。海域含沙量受风浪影响较大,涨落潮时在东北风作用下海域含沙量比较大。从泥沙运动的角度而言,受已建导堤影响,落潮水流和风吹流、波生流等叠加可能形成较复杂的向外水流和环流,携带泥沙向外输运,使高含沙水体运动更远的距离,一般情况下可达-6 m等深线以远。

The remote sensing image analysis of the sea area where Binzhou Port is located has revealed the characteristics of sediment distribution in the sea area and the pattern of sediment movement under different conditions. The cause of the sediment movement is also preliminarily analyzed. The results of the analysis shows that the sediment concentration in the sea area of Binzhou Port is generally high and the sediment concentration in the near shore area is even higher than that in the nearby Huanghua Port area. Sediment concentration in this area is much more affected by waves and winds. At flood and ebb tides, the sediment concentration is higher under the action of northeast winds. From the viewpoint of sediment movement, with the moles being completed, the superposition of ebb flow and flow generated by winds and waves may produce complex outbound flow and circulating flow, carrying the sediment outbound from the port area, thus causing the water body containing sediment to move further away. Generally, the sediment can move as far as away from the fathom line of-6.0 m.
