- Abstract:
-
The influence of soil hydraulic erosion on soil physical and chemical properties is of great significance to control soil erosion and take reasonable soil and water conservation measures. From seven aspects of the physical and chemical indicators of soil quality, such as soil bulk density, soil aggregate, soil grain composition, soil organic carbon, soil nutrient, cationexchange capacity, and soil pH value, the research results of soil water erosion effects on soil quality were summarized. The processes and the mechanisms of the effects of soil water erosion on physical and chemical indexes of soil quality were systematically studied. Soil physicochemical basic index factors reflecting the soil water erosion were screened. The responses of these index factors to soil water erosion conditions were analyzed. The present existing problems of the effects of soil hydraulic erosion on soil physical and chemical properties were discussed, and the future key research directions were looked forward in order to provide references for in-depth research on the interaction and feedback mechanism between hydraulic erosion and soil physical and chemical properties, and the basic theoretical basis and research ideas for soil quality evaluation.
