| 摘 要： | 为获得反映海区磁异常分布的磁异常图,海洋磁力测量数据处理中需要将离散数据通过插值方法进行格网化。给出了几种常用的数据格网化方法,并采用磁异常均匀分布和复杂分布情况对方法有效性进行了评价。结论表明:磁异常分布越复杂,对插值方法的要求越严格,无论是磁异常均匀分布还是复杂分布情况,Kriging法的效果最好,建议在海洋磁力测量数据处理中使用。

| Abstract: | To obtain the magnetic anomaly map of the surveying area,the interpolation methods must be adopted in the discrete data girding.The Kriging,Shepard and triangulation with linear interpolation method have been given.The validity of each method in the marine magnetic survey data girding has been tested by the observed data.The conclusions show that the more complex of the magnetic anomaly distribution,the more strict will be the requirements of the interpolation method.Kriging method can be effectively applied in both uniform distribution and complex distribution areas. |
