在研究目标地质体从而解决地球物理问题的过程中，数学建模是非常重要的一个环节，通常使用的是四边形网格模型，而本文所研究的是对目标地质模型进行高精度Delaunay 三角网格剖分，通过与四边形网格模型的对比得出：Delaunay 三角网格剖分模型相对于四边形网格模型具有更高的精度，在反映地质界面形态、地质地貌特征以及重磁数值计算和研究中具有明显的优势。%In the process of researching geological objectives to solve geophysics problems, mathematical modeling is a very important aspect, it commonly uses quadrilateral mesh model, and this paper studies the geological model of the target precision Delaunay triangulation split. By contrasting with the quadrilateral mesh model derived, the results are obtained that Delaunay triangulation mesh generation model has higher accuracy than the quadrilateral mesh models, it has obvious advantages in reflecting the geological interface formations, geological and geomorphological characteristics and magnetic numerical calculation and research.
