三角网法提取地壳垂直形变速率等值线

Extraction of the Vertical Crustal Deformation Rate Isograms Based on the Triangulated Irregular Network Method

为深入分析并研究特定区域的地壳垂直形变趋势,本文以含高程变化量的离散地形数据点为基础,利用三角网法提取了地壳垂直形变速率等值线。结果表明,该方法具有一定的可行性与参考价值。

In order to make deep analysis and research on the trends of vertical crustal deformation in some specific areas , this paper used triangulated irregular network method to extract the vertical crustal deformation rate isograms based on the discrete terrain data points which contain the amount of the elevation change .As a result, the consequent map proves that this method is feasible and valu-able to a certain extent .
