Simulation study on dynamic mechanism of land use and soil erosion in loess hilly regions of Shanxi and Shaanxi provinces

摘要

SOIL erosion in the hilly region of Shanxi and Shaanxi provinces is very severe, and unreasonable land use is the main reason. There have been many research reports on the prediction of soil erosion, and most of them use regression methods, The resulting co-relative equations are used to predict small-scale erosion of fields or farms and to select agricultural measures. In this study, long-term dynamic changes of land use and soil erosion on a large scale were simulated for the first time, by using a simulation model with systematic running and regulating mechanism.
