Abstract作物及灌草植被覆盖对川中紫色土区土壤侵蚀有着重要影响。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,与实测植被高度、盖度以及叶面积指数进行对比,评估WEPP的作物生长模拟的有效性。研究结果表明: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。WEPP模型作物生长模块并不适用于模拟林地下层的灌草植被的盖度。
Other AbstractCover of crop, grass and shrub has substantial effect on soil erosion in the purple soil area of central SiChuan province.A simulation of crop and vegetation growth was carried out in Chenjiawan watershed by using the crop growth module in Water Erosion Prediction Project.The simulated height, canopy and LAI of crop and vegetation of were compared with measured values.The results show that the crop growth module in WEPP can simulate crop height reasonably, and predicts the growth trend of canopy, LAI of vegetation to some extent.The crop growth module of WEPP should not be used to predict canopy of vegetation under forest.
