Therefore, the purpose of this study is to investigate the spatio-temporal characteristics and main influencing factors of soil wind erosion in northern China, and propose effective control measures. In this study, remote sensing technology, spatial analysis method and statistical analysis method will be used to analyze the soil wind erosion in northern China in recent decades. The research will focus on the following aspects: (1) the spatio-temporal distribution characteristics of soil wind erosion in northern China; (2) the main influencing factors of soil wind erosion in northern China, such as precipitation, soil type, topography, etc.; (3) the analysis of the effects of different control measures on soil wind erosion. Through the research, we can gain a deep understanding of the status quo of soil wind erosion in northern China, and propose feasible and effective control measures to maintain regional sustainable development.Keywords: northern China, soil wind erosion, spatio-temporal variation, influencing factors, control measures.
