应用从卫星遥感图像中提取的平均高潮线水域面积和水边线水域面积推算零米以下水域面积,以及结合潮位实测资料推算海湾纳潮量与沉积速率的方法,得出胶州湾现有(1988年)零米以下水域面积为257km~2、纳潮量为9.48×10~8m~3。这些数值比历史数据减小。胶州湾1963—1988年间的平均沉积速率为1.4cm/a,是1915—1963年间的2.7倍。文中还对湾口最大涨潮流速的推算方法进行了探索,应用于胶州湾得出最大涨潮流速为1.2m/s,也比历史数据有所减小。
Applying the average climax water area extracted from satellite remote sensing images and the waterside watershed area to calculate the water area under zero meters and combining the measured tidal range data to calculate the amount of Nadu and sedimentation rate in the Gulf, ) The area of water below zero meters is 257km ~ 2, and the amount of noctulence is 9.48 × 10 ~ 8m ~ 3. These values are lower than historical data. The average sedimentation rate of Jiaozhou Bay during 1963-1988 was 1.4cm / a, 2.7 times that of 1915-1963. In this paper, the calculation method of the maximum flux at the mouth of the bay is also explored. The maximum flux at the Jiaozhou Bay reaches 1.2 m / s, which is also lower than the historical data.
