摘要
提出一种数值化的土壤侵蚀强度分析方法。对于方法设计、数据组织与管理、土壤侵蚀强度模型的建立进行了系统阐述。该方法已经在相关研究中应用，并取得了良好的分析结果。同时提出采用土壤侵蚀指数来分析土壤侵蚀强度的分析方法。
A numerical soil erosion analysis method based on remote sensing and GIS technique was developed. By applying overlay method to integrated analysis of the special subjects, such as land use, land cover, geomorphology, hydrologic and climate data, the soil erosion index was calculated with the model to determine the soil erosion degrees. This method was used in the study on soil erosion degree of central Tibet and a good result was obtained.
