摘　　要：水深测量中感潮水域通常采用分带法进行水位改正。利用水位站与测点的平面位置逐点进行水位改正,不需进行分区,同时能有效提高水深测量的整体精度。新方法有利于计算机编程实现。Zoning-method is usually applied to correct water-level in water-depth survey in tide-sensitive areas. Comparatively, to correct water level according to the planar correlation between water-level gauging stations and surveyed points, can avoid zoning the surveyed area, and effectively improve the accuracy of water-depth survey. In addition, the new method is convenient for programming with computer.
