Reseach on the Verical Crustal Movememnt in Xianshuihe Area at Present Time with Multiguadric Function

Being used the multiguadric function suggested by Hardy professor of U.S.A,in this paper,and being considered the complexity and the irregularity of the velocity surface of vertical crustal movement and the inhomogeneity of the distribution of the benchmarks that the information of velocity surface are obtained from,a hyperboloid is selected as a kernel function and a glossy coefficient δ is decided to be equal zero.The calculation are done for the leveling network from 1965 to 1988 repeated over several periods.The forecasted results of the velocity surface of the vertical crustal movement are got in Xianshuihe area nowdays.It shows fairly the feature of the vertical deformation of the crust and of the strain accumulation in Xianshuihe area in these days.
