摘　　要：本文通过总结土壤侵蚀模型研究成果,概括了土壤侵蚀模型的主要类型及各类模型的适用范围,在第一次内蒙古水土保持普查的项目背景下,结合本省的土壤侵蚀特点,利用3S技术与已有侵蚀模型和地面数据相结合的方法分析了影响土壤侵蚀的主要因子,包括:降雨因子、土壤可蚀因子、地形因子、生物措施因子及工程与耕地措施因子。初步建立了本次普查的土壤侵蚀模型,在此基础上提出了基于3S技术与地面数据相结合提取侵蚀因子的方法,并建立了模型参数与侵蚀因子的关系模型。This paper which concludes the research results of soil erosion models and introduces the main types of soil erosion models and range of application of these models. Under tile first Inner Mongolia Soil and Water Conservation background, combined with soil erosion features in this province, the main factors of affecting soil erosion were analyzed by a method which used 3S and existing models with ground data. The main factors include： rainfall factor, soil erodibility factors, topography, biological measures factors, engineer- ing and land measures factors. Then the soil erosion model is established preliminary. And on this basis, a method to extract erosion factors which is based on the 3S and ground data is put forward. At the same time, establishing the relational model between parameters and erosion factor.
