摘　　要：在总结各传统水位改正法基本原理及假设条件的基础上,分析了现行的GB 12327-1998《海道测量规范》中关于验潮站布设的条目:潮汐类型相似及最大潮高差与最大潮时差的量化指标要求不能保证站间的水位关系满足传统水位改正方法的假设条件。基于假设条件,提出了评价指标与方法:(1)对于站间水位相似性,提出由同步水位曲线定性判断和最小二乘拟合法推算的中误差为量化指标的定量分析相结合的评价方法;(2)对于站间水位均匀变化,提出由站间是否存在阻挡以及潮波图定性判断、中间站点处水位内插误差为量化指标的定量分析相结合的评价方法。The principle and hypothesis conditions of the traditional methods for water level correction are summarized .The feasibility of the items about tidal stations layout in specifications for hydrographic is analyzed. Similar type of tide,two indicators of the maximum tidal level difference and the maximum tidal time difference canJ t meet the hypothesis conditions. Then evaluation index and assessment method are cited. （1） The water level similarity between stations can be estimated by the diagram of water level, and the fitting mean square error of the least square fitting model.（2） The even variation of water level between stations can be estimated by the Co-tidal map,blocks between stations,and the interpolation error of the middle station.
