摘　　要：针对近年来我国日益严重的水土流失情况,应用GIS和RS技术,结合RUSLE水土流失公式,并采用SPOT5遥感影像对某地区内的土壤流失情况进行评估。研究表明,该地区内约有18%的地区水土流失严重,该研究结果可为同类地区水土保持的政策制定提供有效借鉴。In view of the increasing serious situation of soil erosion in recent years in China, this paper applied GIS and RS technology,combined with RUSLE soil erosion formula, and used SPOT5 remote sensing image to evaluate the soil erosion situation in an area. The study shows that about 18% of the area has serious soil erosion. The results of this study can provide an effective reference for the policy formulation of soil and water conservation in similar areas.
