摘要

选取合适的网格化方法和合理的参数设置,在绘制物化探等值线图时发挥着重要的作用。为了使绘制的物化探等值线图更加精准,绘图方法更加科学。本文发现非正交测网的高精度磁测和土壤地球化学测量数据绘制等值线图时,不同的网格化方法会产生不同的效果。通过研究分析三角剖分方法和克里格方法网络化的原理和特点,总结得出在非正交测网数据成等值线图时,三角剖分法网格化对比于克里格法网格化,具有更好的应用效果。
        An appropriate gridding method and reasonable parameters play an important role in plotting contour maps using data from geophysical or geochemical survey networks. In order to make the geophysical contour maps more precise,and make the drawing methods more scientific. This paper addresses the issue why different gridding methods can produce varied effects during preparing contour maps using data from non-orthogonal networks.Through research of the triangulation method and the kriging method,we suggest that the triangular gridding is superior to Kriging gridding when drawing contour maps using such data.
