摘　　要：本文介绍了瓯江口外滨海区的一次滩涂测量,主要内容有:一是关于在原有控制基础不佳的海岸,如何适应测区特点应急布网而又能保证成图基本质量以及在滩涂上进行三角观测和埋设大型标石的经验。二是关于先布设断面,以极坐标法,放宽最大视距限值施测滩涂地形的经验和精度估计。A record on the surveying of seabeach at coastal region outside the mouth of Onjiang River is included in this paper The two main contents are: (1)about the experiences how the frameworks are established rapidly not only to suit the charac teristics of the surveying area but also to pledge basic quality of the result, where the bases of control along the coast are not complete,ard how the triangulation is carried out with the large monuments covered up on the seabeach; (2) about the experiences that how the topography of seabeach is surveycd and the estimations of accuracy are made with the method of polar coordinates and the limit value of the biggest distance of view relaxed after the section has been arranged.
