摘要
针对小流域基础空间数据复杂多样,且难以管理等问题,选取河北省平泉县东北沟小流域为研究对象,运用GIS与RS技术,利用1∶10000比例尺、5 m分辨率的DEM与空间分辨率为0.61 m的Quickbird影像,对水文、地形、土地利用等多种流域空间数据进行挖掘,并结合二者建立了小流域三维空间模型,同时创建了空间数据库对其进行统一高效管理。结果表明:GIS与RS技术能够为小流域数据空间获取,流域规划建设及管理提供高效的技术手段。
Dongbeigou watershed,in Pingcuan county of Hebei province,was selected as the case study area in terms of complicated and various spatial data of small watershed,which is difficult to be managed.The spatial data of hydrology,topography,land use and many others were mined using GIS and RS based on Quickbird remote sensing image with 0.61 m spatial resolution and DEM with 1∶10 000 scale and 5 m resolution.Meanwhile,the 3D model of the small watershed was set.And the geography database was also established to manage the spatial data.The results show that the technology of GIS and RS can be the high efficient methods for obtaining spatial data and the construction and management of the small watershed.
