摘要

利用自然邻点方法对离散的中国大陆地区大地热流观测数据和相对均匀的台湾地区重力观测数据进行了插值计算,并与地学中几种常用插值方法进行了比较.结果表明:自然邻点插值方法更适于处理分布不规则的观测数据.

Abstract

The interpolation is an usual method to represent the continuous geophysical fields. The Natural Neighbor Interpolation (NNI) is a new method based on the Voronoi Diagram. We use the NNI method and some common interpolation methods to interpolate the thermal flow data of Chinese Mainland and the gravity data of Taiwan province. Comparing the NNI method with the others, we consider that the NNI method is more fit for irregularly distributed geophysical data.
