摘　　要：针对矿山开采沉陷所引发的地表形变信息表达和准确制图问题,该文结合遥感影像与地形图等数据,基于矿区开采沉陷变形预计结果和三维可视化方法,对矿山开采沉陷专题信息表达及其GIS制图新模式进行了探究。实现了矿区地表下沉、水平移动、水平变形、倾斜和曲率的形变信息应用分析与可视化,以及下沉盆地水淹范围模拟图、三维地表变形影像图、特定区域变形分析图、采动损坏等级分布图等制图功能。Land surface deformation caused by mining subsidence is a serious geological disaster,effective expression and accurate drawing of the deformation information can greatly reduce the cost of mining deformation control.Combining with the data of remote sensing images and topographic maps,this paper researched the thematic information expression and some new GIS mapping modes of mining subsidence based on the deformation predicting results and 3Dvisualization methods,realized the application analysis and visualization of surface deformation information,the 3Dsimulation map flooded by water in the subsidence basin,the 3Dsurface-deformation image maps,surface-deformation analysis maps in the specific zone and the damage-grade distribution maps in the mine area with mining subsidence about the surface subsidence,horizontal movement,horizontal deformation,inclining and curvature.
