Abstract：Selecting kernel function in fitting region vertical deformation field using multi-surface function is an important aspect .Four kernel functions are compared in fitting vertical deformation field of three dif-ferent regions in this paper ,and the best kernel function is selected by the external accuracy and the con-tour map .Tapered surface function is a good kernel function with a strong adaptability by comparison ,and it can well fit the rise and fall of region vertical deformation field .Therefore it has some practical values .
