| 摘 要： | 引进了地统计学中的变异函数,通过对我国多幅航海图和港湾图水深数据的计算分析,初步揭示了水深场的空间变异特征.结果表明:水深点的空间相关性与相互间的距离和所表征的海底地形有关；在不同的尺度下水深场的空间变异特征不同；水深场的空间变异存在各向异性.

| Abstract: | Semi-variogram is a very useful spatial analyzing method in geostatistics field.The paper introduces this method into a study on spatial analyzing of sounding field.By analyzing the data of nautical charts and harbor charts of our country,the result shows that,the soundings spatial relativity is pertinent to the distance and the terrain of seabed.Meanwhile,the characters of spatial variation are different on the different scale.Lastly,the spatial variations of sounding field are different in different directions. |

| Keywords: | sounding field semi-variogram spatial structure anisotropy |
