摘要
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。
The paper introduces the application of DTM to groundwater flow field display. The paper discusses the advantages and disadvantages of application. The software has some features of strong functions(the planar and stereo displays of contour of groundwater table, flow lines, legend etc.); easy operation(eg.rotating, zooming and minifying etc.);obtaining some parameters (such as water table at one point, hydraulic gradient of two points, water catchment area etc). The software provides the basis for the research of complex groundwater flow visualization, which needs large amount of data to ensure high precision. The DTM is worth studying more deeply.
