| 摘 要： | 区域似大地水准面精化研究主要是用于测绘学科，将精化结果应用到绘制地形图中，减少户外工作量，降低人力成本。传统采用的Kriging法在精化时会出现误差，精度值不达标。所以，改用了一种基于已知的拟合残差进行计算的改进方法重新精化研究。将改进的Kriging法与传统的Kriging法对比后，改进后的方法精化结果的拟合精度明显要高于传统方法。

| Abstract: | Areas like geoid refine the study is mainly used in surveying and mapping. Re- fine the results applied to map landscapes reduces the outdoor work and the manpower cost. The traditional error occurs on the elaboration, Kriging method accuracy value is not up to standard. So, a kind of fitting residual is calculated based on known improvement methods to the elaboration of research. The improved Kriging method is compared with traditional Krig- ing method, the results of the improved method is better than that of traditional method sig- nificantly. |
