黄土高原地处干旱半干旱地区,加之水力侵蚀和风力侵蚀的交替进行,使得该区土壤侵蚀尤为严重。本文通过对一些学者在黄土高原地区进行坡面土壤侵蚀产流产沙相关研究分析,总结了部分试验方法及土壤颗粒启动、水动力参数等方面的计算方法。通过一系列的试验研究,希望能为建立黄土高原土壤侵蚀预测模型提供科学依据。
The Loess Plateau is located in arid and semi-arid regions, combined with the alternation of hydraulic and wind erosion, which makes the soil erosion especially serious. Based on the research and analysis of runoff erosion and sediment production by some scholars on the slope soil erosion in the Loess Plateau, this paper summarizes some test methods and calculation methods of soil particle initiation and hydrodynamic parameters. Through a series of experimental studies, I hope to provide a scientific basis for the establishment of soil erosion prediction model in the Loess Plateau.
