Research on Soil Erosion Monitoring System Based on UAV Aerial Images

Unmanned aerial vehicle (UAV) aerial images have the characteristics of high precision, real-time and comprehensiveness. If the acquired images and aerial images of unmanned aerial vehicles are properly applied to the compilation of the implementation plan of comprehensive soil erosion control, it can get twice the result with half the effort and improve the efficiency of the scheme compilation, and it is also an ideal non-contact and efficient reconnaissance method. At present, with the continuous improvement of science and technology in China, most industries have started to use science and technology, especially in the civil engineering industry, and the corresponding managers’ proficiency in the use of UAV technology and remote sensing technology has been continuously improved. In the supervision of soil and water conservation, workers can effectively improve their efficiency and convenience in the process of work through technology. In this paper, with the help of high-precision digital surface model and digital elevation model established by UAV aerial data, the typical small watershed of Loess Plateau, Huangtuwa, was studied, its land use status and topographic changes were analyzed, the soil erosion of different land use types was calculated, the distribution law of land use types in Huangtuwa small watershed and its influence on soil erosion were discussed, and the contribution factors and contribution rates of soil erosion were summarized. Furthermore, it reveals the relationship between soil erosion and land use, climate and human activities, and provides a feasible research case for the arrangement of subsequent agricultural production activities and the prevention and control of soil erosion in the Loess Plateau.
