摘要：

作物及植被对川中紫色土区土壤侵蚀有着重要影响。本文通过使用土壤侵蚀过程模型WEPP的作物生长模块对陈家湾小流域作物及植被生长进行模拟，获取高度、盖度以及叶面积指数，与实测值进行对比。通过分析得出：WEPP模型作物生长模块对作物高度模拟较高，能够预测植被盖度、叶面积变化趋势但有不同程度的高估现象。

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.
