该文将DTM(数字地面模型 )应用于地下水流场的显示 ,讨论了DTM在显示地下水流场中的优点与缺点 ,它具有功能强大 (平面、立体显示地下水的等水位面图 ,流线图显示 ,图例显示等 )、可操作性强 (如旋转、放大、缩小等 )等特点 ,还可获取一些重要的信息 (如任一点的水位、两点的水力坡度、给定范围内的汇水面积等 ) ,可以为地下水的复杂流动提供可视化的依据。同时 ,它要求数据量较大 ,才能获得较高的精度。DTM在地下水流动中的应用值得进一步探讨
In this paper, DTM (Digital Terrain Model) is applied to the display of groundwater flow field. The advantages and disadvantages of DTM in displaying groundwater flow field are discussed. The DTM has powerful functions (such as flat surface, Display, legend display, etc.), operability (such as rotation, zoom in, zoom out), etc., but also access to some important information (such as any point of the water level, two hydraulic gradient, within a given range of catchment Area, etc.) can provide a visual basis for the complex flow of groundwater. At the same time, it requires a large amount of data in order to obtain higher accuracy. The application of DTM in groundwater flow deserves further discussion
