Abstract:: [Objective]Soil erosion caused by compound forces is obvious in Mollisol region, studying the annual alternating superposition of natural driving factors for soil composite erosion in different typical intervals in Northeast Mollisol Region has practical significance for soil erosion control in the region. [Methods]We analyzed and compared the spatiotemporal distribution of natural driving factors of water, wind, freeze-thaw, and snowmelt in 11 typical regions of the region, and clarified the alterative and superposition characteristics of each factor. [Results]In terms of time, the driving factors of hydraulic power, wind power, freeze-thaw and snowmelt in northeast Mollisol region occurred in superposition and alternation within the year. In spring, the driving factors of wind power, freeze-thaw and snowmelt were the most complex. In Summer, the driving factors of hydraulic power, wind power and freeze-thaw were the main driving factors. In autumn, the combined effects of hydraulic power, wind power and freezing and thawing were limited, while in winter, the effects of wind power and freezing were obvious. In terms of space, the hydraulic driving effect gradually decreased from southeast to northwest. Wind effect gradually decreased from southwest to northeast. The freeze-thaw effect gradually decreased from southwest to northeast. Snowmelt gradually decreased from northwest to southeast. According to the different characteristics of erosion driving factors, the whole region was divided into hydraulic, water-wind-freeze-thaw, water-wind-snow melt, water-freeze-thaw-snow melt erosion zones, and targeted soil erosion control could be carried out in different regions. [Conclusion]Each camp showed obvious temporal and spatial differences in their erosion performance.The characteristics of the composite erosion driving factors in a year were obtained based on the alternating superposition of natural driving factors within a year, providing reference for targeted soil erosion control and in-depth research on the composite erosion prevention and control in different regions.
