摘要
将辽东湾北部浅海海域划分为12个区,对各区悬沙浓度进行了定量计算,进而分析了悬沙的时空变化,探讨了影响悬沙高值区出现的因素和辽东湾北部海域悬沙的输移方向。结果表明:风速对于海域整体悬沙浓度和浑水区出现的范围有明显影响;辽东湾北部海域悬浮泥沙浓度高值区的出现与风向和潮流的方向有关,而与风速关系不大;近岸地区,涨潮表层平均悬沙浓度明显比落潮时大5,～10m的深水区,落潮表层平均悬沙浓度明显高于涨潮;涨潮悬沙输移主要表现为SW—NE方向,落潮则相反。
This paper divides the shallow waters of the North Liaodong Bay into 12 zones,then analyzes the spatio-temporal variation of suspended sediment concentration and its transport direction,and further explores the high suspended sediment zones in the North Liaodong Bay.The study shows that：（1）The wind speed of the whole sea area has significant effect on suspended sediment concentration and its diffusion range;（2）The location of high suspended sediment concentration is related to the wind direction and the tidal current direction,but is irrelevant to the wind speed;（3）In the near-shore zones the average surface suspended sediment concentration at flood tides is higher than that at ebb tides,but in the 5~10m deep-water zones,it is opposite;the main transport direction of suspended sediment is SW-NE during flood tides,and vice versa during ebb tides.
