地理信息系统 (GIS)在水土保持初设中的应用日益普遍。由于使用软件不同 ,在处理方法和技术上有所不同。以锡林河水库东沟小流域为例 ,探讨了运用地理信息系统 (GIS)软件 Geom edia进行流域空间分析 ,获取水保初设数据 ,绘制和打印所需图版的应用方法 ,使水土保持小流域治理初设实现规范化、科学化、现代化 The application of Geographic Information System (GIS) in the initial design of soil and water conservation is increasingly common. Due to the different software, in the treatment methods and technologies are different. Taking Donggou small watershed of Xilinhe Reservoir as an example, this paper discusses the application of Geom edia GIS software to analyze the spatial distribution of watersheds, obtain the preliminary data of soil and water conservation, draw and print the required plates, The initial establishment of basin management to achieve standardization, scientific and modern
