摘要
在小流域治理中 ,为了提高水库规划的精确度和速度 ,提出了基于GIS技术来实现小型水库规划的方法。主要是基于GIS技术的库容曲线的制作方法 ;小型水库规划的可视化。在GIS中 ,真实地形在计算机中的表达用数字高程模型 (DEM )表示 ,水库规划的三维可视化环境的实现需利用OpenGL技术。
In order to improve the precision and speed of reservoir planning in harnessing of small river basin, methods of small_sized reservoir planning technique based on GIS are proposed. The main methods include drawing reservoir_capacity curve based on GIS and visualization of small_sized reservoir planning. In application of GIS, digital elevation method (DEM) is used to express actual topography in computer, and three_dimension visualization environment of reservoir planning is realized by using technique of OpenGL.
