Measuring Compound Soil Erosion by Wind and Water in the Eastern Agro–Pastoral Ecotone of Northern China

Land degradation induced by soil erosion is widespread in semiarid regions globally and common the agro–pastoral ecotone of northern China. Most researchers identify wind water as independent processes, there a lack research regarding relative contributions interactions between them what referred to here compound (CSE). CSE may occur situations where more effectively erodes surface already subject erosion, rainfall impacts previously exposed or material deposited erosion. In this paper, we use Chinese Soil Loss Equation (CSLE) Revised Wind Erosion (RWEQ) calculate rate map distribution three types classified (i) (wind-erod), (ii) (water-erod), (iii) (CSE-erod) for study area that spans than 400,000 km2 sand- loess-covered According minimum threshold values mild water-erod, wind-erod, CSE-erod land occurring across 41.41%, 13.39%, 27.69% total area, while mean rates were calculated 6877.65 t km−2 yr−1, 1481.47 5989.49 respectively. predominantly distributed around margins those areas experience independently. The CSLE RWEQ do not facilitate direct assessment so these equations only derive estimates actual mechanisms controlling require further field investigation. It concluded an important but underappreciated process needs be accounted assessments it has substantial on agricultural productivity sustainable development with sandy and/or surfaces.
