根据我国五十年代末进行海岸带深度测量的潮汐保证情况,探讨海岸带调查中深度测量的分级控制基础。根据平均海面、深度基准面和瞬间海面各不相同的要求,有区别地分开进行观测,以代替每个验潮站都进行长期观测,使有限的潮汐观测力量用于保证深度测量需要的同时,能够尽可能多地获取海岸带的潮汐资料。 According to the tidal assurance of coastline depth measurement in China in the late 1950s, the basis of hierarchical control of depth measurement in coastal survey is discussed. Based on the different requirements of the average sea level, depth reference plane and instantaneous sea level, observations are separately made to replace the long-term observation of each tide gauge station, and the limited tide observation force is used to ensure the depth measurement needs. Get as much coastal tide information as you can.
