In this paper, one structured refining meshing scheme is presented for Earth, which can make all mesh sizes in the Earth more uniform, and refine the meshes near the surface area so as to meet the need of the geophysical analysis.

• 本文提出了一种地球结构化网格的生成和加密划分方案，可以对整个球体形成较为均匀的网格，并能够对近地表的区域完成网格加密以达到地球物理分析的需要。
