摘要

基于Landsat TM5(2007-5-19)和DEM(1∶50000)对张家口官厅水库上流域土壤侵蚀进行了评价。(SL190-2007)，采用多因素综合评价方法，选取土地利用、植被覆盖和坡度作为评价因子。结果表明:极低土壤侵蚀面积占43.36%，土壤侵蚀强度较大的斑块较为破碎，难以统一治理;

Information extracting and assessment of soil erosion based on remote sensing information in the upper basin of Guanting reservoir

Soil erosion of the upper basin of Guanting reservoir in Zhangjiakou was assessed based on Landsat TM5(2007-5-19) and DEM (1∶50000). (SL190-2007) and the multifactor comprehensive method were adopted, and land use, vegetal cover and slope were selected as assessing factors. The result shows that very low soil erosion covers 43.36%, and the intensive soil erosion patches are rather fragmentized and difficult to be treatment uniformly.
