摘要:
以西宁市周边小流域为研究区域,在GIS软件Arcview和Microimages TNT的支持下,建立流域的空间数据库,利用GIS的栅格数据空间分析功能,将流域空间按10 m×10 m栅格化,根据合适的USLE因子算法生成各因子栅格图,借助GIS空间数据分析功能,实现了西宁市土壤侵蚀量估算和土壤侵蚀强度分级,为西宁市土地利用和水土保持提供科学依据.
Abstract:
The paper researched estimation of soil erosion on the base of GIS platform by integrating USLE.Taking suburb watershed of Xi’ning city as research area,spatial database of watershed have been established by GIS soft,i.e.Arcview and Micro images TNT.Based on the GIS’s function of raster spatial analysis,the watershed is discreted into uniform grids with the cell of 10m×10m and established Grid data after selecting reasonable USLE factor values.Prediction of soil erosion and classification have been achieved and spatial analysis function,scientific basis for land-use and soil conservation in suburb watershed of Xi’ning city will be provided.
