摘要
利用14景环境与灾害监测预报星(HJ-1A/1B)CCD相机卫星数据,提取不同潮位下渤海海湾的水域面积。结合潮汐订正的方法,计算获得了2010年辽东湾、渤海湾和莱州湾的纳潮量分别为9.32×1010m3、3.03×1010m3和0.54×1010m3。计算结果将为渤海动力学研究提供参考。
The water areas of the bays in the Bohai Sea have been extracted by using fourteen frames of satellite images,which were imaged by CCD sensors fixed on A/B satellites for environment and disaster monitoring and forecasting（HJ-1A/B）.The tidal prism of the Liaodong Bay,Bohai Bay and Laizhou Bay in 2010 have been calculated based on both the areas and a method of tidal calibration,the values of which are 9.32×1010 m3、3.03×1010 m3 and 0.54×1010 m3 respectively.The results will be the important referenced parameters of the oceanic dynamical study in the Bohai Sea.
