Abstract:

Crop and vegetation has great effect on soil erosion in the purple soil area of central SiChuan Basin. A simulation of crop and vegetation growth was carried out in Chenjiawan watershed by using the crop growth module of Water Erosion Prediction Project, The height、canopy、LAI of crop and vegetation of simulation results was compared with measured value. Comparison results show that the crop growth module of WEPP simulates crop height in a high precision, can predicts the growth trend of canopy、LAI of vegetation but have some high results in some extent.
