摘　　要：本文介绍在水网和长距离(2Km左右)跨江跨河地区,进行四等三角高程测量的试验研究。通过对观测方法和设备的改进以及进一步实验研究,有望实现更长距离和更高精度的跨江跨河三角高程测量以及取代现有的跨河水准测量。This article presents a point that we can carry through the fourth grade trigonometry level surveying at water area with long distance (about 2km) over river. It抯 possible to get the result of the longer side and more precise trigonometry level surveying through improving the method of observation, ameliorating the equipment and carrying on further experiment. It will replace the present level surveying across the river.
