克立金法預估重力異常與降低變方分析規劃重力施測點之研究

Abstract

本研究是以一般克立金法對二組大小不同的重力資料,測試其自由空間重 力異常預估成果,與最小自乘密合曲面法作比較.並以一,二等三角點作為 可能施測點,使用克立金法引申之降低變方分析,在三角點中選擇最佳施測 點. "Ordinary Kriging Method" is used to test the predicted results of free air gravity anomaly , then comparision are made between the results obtained from "Ordinary Kriging Method" and those from "The Method of Least-Sequare Surface Fitting". Triangulation points are chosen to be the possible station positions, and "Variance Reduction Analysis" which extended from "Ordinary Kriging" are adopted to extract the optimal gravity station positions out.
