摘　　要：在三维景观建模技术日益发展的当下,产生了多种建模方法,但多数传统方法对于大范围的三维景观建模工作显得效率较低,且都难以进行相关的三维分析。基于MapGIS软件的快速三维景观建模方法通过对遥感影像数据和数字高程模型数据(DEM)的充分利用,能够在二维矢量化要素的基础上直接生成三维模型,并进行相关的三维分析。成都理工大学东区校园三维景观建模实例表明,MapGIS具有操作简单、快捷高效等优势,为大范围三维景观建模的快速实现以及快速三维分析提供了一个很好参考。With the increasing development of 3D landscape modeling technology,a variety of modeling methods have emerged,but most of the traditional methods are inefficient for large-scale 3D landscape modeling,and it is difficult to carry out related 3D analysis.By making full use of remote sensing image data and digital elevation model data(DEM),the fast 3D landscape modeling method based on MapGIS software can generate 3D model directly on the basis of two-dimensional vectorization elements and carry out related 3D analysis.The example of 3D landscape modeling in the eastern campus of Chengdu University of Technology shows that MapGIS has the advantages of simple operation,high speed and high efficiency,which provides a good reference for the rapid realization of large-scale 3D landscape modeling and rapid 3D analysis.
