| 摘 要： | 在全世界范围内土壤侵蚀对农业生产、地基和水质量都具有负面影响。因此,进行土壤侵蚀评价是非常重要的,但其往往受到数据可用性和数据质量的限制。利用遥感技术有助于土壤侵蚀的评价,它可以为土壤侵蚀评价提供所需的空间数据。在过去的30年许多研究在这方面做了不同深度层次的工作。本论文主要回顾了利用遥感技术评估土壤侵蚀影响因素的方法。土壤侵蚀影响因素的评估包括：地貌、土壤特性、植被覆盖和管理措施。

| Abstract: | Erosion has a negative effect on agriculture, infrastructure and water quality in the world. Then it is very important to assess erosion,which is limited by data availability and data quality. Remote sensing contributes to assess erosion,and it can provide the spatial data, which is required by assessing erosion. During the past 30 years a great deal of research has been done in this field. The authors mainly review methodologies of assessing erosion controlling factors by remote sensing. Erosion controlling factors include topography,soil,vegetation,conservation practices and tillage. |
