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.
Key words： interpolation; natural neighbor; solid earth structure data
