多面函数拟合法及其在建立中国地壳平面运动速度场模型中的应用研究

Hardy Function Interpolation and Its Applications to the Establishment of Crustal Movement Speed Field

基于现有的GPS观测值 ,将多面函数拟合法用于速度场模型的建立 ,得到了目前中国覆盖范围最广、分布最均匀。

The Global Positioning System (GPS) has been widely used in survey and its relative areas in China since the end of 1980s.Several large_scale high precision GPS networks have been established since 1991.The integrating adjustment of these GPS networks has been finished.But the quantity of high precision GPS points is limited,so the crustal movement image of the surveyed GPS points is half_baked.For these reasons,for the first time we use hardy function interpolation to establish a largely_covered and valuable speed field model,with which the crustal movement imags are also obtained.
