| 摘 要： | 探讨了利用遥感技术进行小流域土壤侵蚀计算的方法。应用通用土壤侵蚀方程,借助RS和GIS技术,对模型各参数因子进行精确计算,实现了基于栅格信息的土壤侵蚀计算模型。选择黄河皇甫川五分地沟小流域作为典型研究区,讨论了适宜植被盖度对减小土壤侵蚀模数的影响。

| Abstract: | Universal soil loss equation(USLE)as a key quantitative evaluation model for soil erosion,was used to precisely calculate the parametric factors of the model based on the RS and GIS technologies.In this paper,these above-mentioned methods were initially used to study the relationship between the soil erosion and suitable vegetation coverage in Wufendigou typical region in the Huangfuchuan Valley of the Yellow River.It is proved by the field investigation that the RS method has higher precision than the traditional one,which indicates that the method is very useful for the soil erosion supervision in a small valley. |
