摘　　要：为了表述和评价水深原图及海图水深数据对海底地形的表征能力,引入了水深插值平滑效应新概念,分析了航海图海道测量及海图编辑综合的水深数据选取特性,给出了测线间水深插值平滑效应的评价指标和方法,并进行了实例统计计算,计算结果表明了方法的可行性和有效性。In order to describe and evaluate the token ability of submarine topography by the sounding sheet and soundings in chart, a new concept of smoothness effect of soundings interpolation is introduced firstly in this paper. Furthermore, the sounding selection characteristics of hydrographic survey in the nautical chart and chart editing and integrating are analyzed, and the target and method of evaluating the smoothness effect of soundings interpolation between the survey lines are provided. In the end, the calculating result of the example makes the feasibility and validity of the method clear.
