摘　　要：地壳垂直运动的研究中,多面函数法是一种传统并得到广泛应用的方法。本文通过首都圈和晋冀蒙两个地区的实例,对多面函数和移动法综合拟合模型与多面函数模型等几种模型进行了对比研究。结果表明,多面函数和移动法综合拟合模型在拟合精度上优于其他几种模型,拟合残差更稳定,具有一定的实际应用价值。Multi-surface function method is a traditional and widely used method in the study of vertical crustal movement.Through the two examples of the capital region and Jin-Ji-Meng region,the synthetic model of multi-surface function and movement method is compared with the multi-surface function model and some other models. The results show that the synthetic model of multi-surface function and movement method has a better fitting precision and more stable errors than other several models and it has practical values.
