| Abstract: | We introduced and analyzed five semivariogram models in Kriging method,and interpolated the discrete data separately. The test results verify that the spherical model has the best interpolation precision,and exponential model,power function model,gaussian model also have preferable results. The logarithmic model is not suitable for its' limited calculation when the distance between two points is short. |

| Keywords: | ordinary Kriging method semivariogram gravity anomaly |
