摘　　要：[目的]对遥感技术在土壤侵蚀研究中的应用进行述评,探索土壤侵蚀遥感研究的发展方向,并为研究者快速选择适宜的遥感数据源和研究方法提供参考。[方法]通过文献查阅,从不同研究方面开展综述和分析。[结果]针对不同研究区域和主题,总结了土壤侵蚀研究中常用遥感平台和数据源,综述了遥感技术在区域土壤侵蚀特征识别、监测与尺度效应研究中的应用。以及遥感技术在通用土壤流失方程关键因子获取中的应用。同时分析了目前研究中存在的问题并提出相应建议。[结论]遥感技术作为开展大范围、长时间序列土壤侵蚀研究的重要技术手段,在我国土壤侵蚀研究中发挥了巨大作用。但实际应用中也存在基层遥感数据时效性不强、数据源单一和识别因子针对性不强等问题。其高效应用和推广需要技术层面和人员、经济支持层面共同发展与创新。[Objective] This paper aimed to review the application of remote sensing technology in the research of soil erosion to provide some bases for the development of remote sensing research on soil erosion, and to provide references for researchers to select the appropriate remote sensing data sources and methods. [Methods] The application of remote sensing on soil erosion research was analyzed through literature review in different aspects. [Results] According to the research area and theme, erosion remote sensing platforms and data sources, and the usage of remote sensing technology in regional soil erosion feature recognition, monitoring and scale analysis were summarized. In addition, the application of remote sensing to obtain key parameters in RUSLE was introduced. The problems existed in the current research were also analyzed and some suggestions were put forward. [Conclusion] Remote sensing technology was an important technology to carry out large-scale and long time series of soil erosion research, and it has played a significant role in the study of soil erosion in China. However, there are some problems in practical application. The collaborative development of technology, personnel and economy was needed in the effective use and promotion of remote sensing on soil erosion research.
