摘　　要：地质岩层体积的求取一直是困扰地质学界的一难题.在对基于DEM的地质岩层体积求取方法进行说明的基础上,通过在陕西省长武县进行地质钻探和建立DEM,获得该地区各系岩层深度数据等基础数据及DEM,然后用GIS软件ARCVIEW中的三维分析模块,快速求取出本地区各系岩层体积,并对该方法的精度及注意的问题进行讨论.s: By now, obtaining the volume of geologic terranes has been a difficult problem in geology field. The author firstly discussed the method to calculate the volume of geologic terranes ,and then, with yao抶ian in shaanxi province as a sample area, built the DEM model according to the drilling data in the area. DEM and depth data in different geology periods may be obtained, and then the volumes of various geologic terranes are calculated based on 3D analysis model using GIS software. Finally, precision and open question about this method are discussed. This provides a new method and a train of thought for geology- researchs.
