为获取辽东湾近岸堆积冰特征,利用CCD监测、数码照相和GPS定位等现代技术,通过现场定点连续监视和堆积冰外边缘线踏勘,以及堆积冰外边缘断面的等距离正面照相,获得辽东湾堆积冰边缘流冰运动速度、方向和密集度等参数.统计分析了流冰运动参数与当地潮位、潮流变化的关系,以及堆积冰宽度、边缘断面、高度和起伏角度等几何特征参数.结果表明:堆积冰的形成与平行海岸的潮流速度关系不大,而与流冰厚度、潮位、风速风向有很大关系;堆积冰边缘的流冰运动速度、密集度和潮位直接相关;堆积冰的最大外边缘线不超过零米等水深线;堆积冰高度一般小于2 m,最大为2.8 m;堆积断面起伏的平均切角为22°.
In order to obtain the characteristics of coastal ice accumulation in Liaodong Bay, modern monitoring techniques such as CCD monitoring, digital photography and GPS positioning were adopted to continuously monitor and accumulate the ice outer boundary line survey and the equidistant frontal photograph of the outer edge of the ice accumulation. Such as velocity, direction and intensity of ice flow along the edge of the accumulated ice in the Bay, and the relationship between the parameters of the ice flow and the local tide and tidal current, as well as geometrical parameters such as width, edge section, height, The results show that the formation of the accumulated ice has little to do with the tidal velocity of the parallel coast, but has a great relation with the flow thickness, the tide level and the direction of the wind speed. The flow speed, density and tide level of the ice are directly related to the edge of the ice accumulation. The maximum outer edge line does not exceed the water depth of zero meters. The heap ice height is generally less than 2 m and the maximum is 2.8 m. The average chamfer of the buoyant section is 22 °.
