摘要
针对岩溶地区因具有暗河、地面不连续河流而使得利用DEM和GIS构建数字流域难度较大,以贵州省平湖流域为例,基于DEM和Arc Hydro提出了岩溶地区数字流域的生成处理方法,为构建岩溶地区的分布式水文模型奠定了基础。
It exist underground rivers and discontinuous river in Karst region, which bring about tremendous difficul- ties to construct digital watershed using DEM and GIS. Taking Pinghu watershed in Guizhou Province for an example, this paper proposes a method for extracting and processing digital watershed in Karst region based on the Arc Hydro and DEM. Thus, it provides basis for building distributed hydrological model in Karst region.
