摘要
以黄土高原与毛乌素沙地线交界处能源重化工基地为研究区域,以2003年9月份的ETM遥感数据为基础数据。在GPS野外定点确定土地利用类型,实测样方内植被盖度及遥感信息与GIS空间信息分析的基础上,分析并确定影响土壤侵蚀的因子,合成了该区水土流失现状专题图。在此基础上对榆林北部6县(区)的各类水土流失类型、面积做了全面清查,并分析了该地的水土流失类型、强度及区域分布的分异特征。
Taking the energy and heavy chemical industry area along the boundary of the Loess Plateau and the Maowusu Sandland as study area and the ETM data as main data source,we identified the land use types by GPS,measured the vegetation cover using quadrat method,and analyzed remote sensing and GIS spatial information.The effects of soil erosion factors were determined,and soil erosion map of the area was made. Based on the above results,the erosion types and area of the north of the six counties(districts) of Yu...
