摘　　要：利用费尔哈斯模型的特点,把少量的原始数据作各种处理并基于关联空间、光滑离散函数等概念,建立灰微分方程模型来模拟地表移动的时间过程,求得地表移动的时间响应模型,用生物生长过程来模拟地表移动的时间过程,对预防开采沉陷,对减少地表构筑物的损害及保护地面设施,对减少开采沉陷造成的经济损失是有益的.This paper simulates the ground surface movement by using the model of Verhulst,and derives a serials of time model by using a few observed data to simulate the procession of ground surface movement.It also simulates the procession of ground subsidence by using the growth of living things,The paper is very important not only in theory but also in practice to reduce the harm of ground movement.
