| 摘 要： | 对湖北省秭归县张家冲水土保持试验站10个试验小区连续5a的径流、侵蚀观测数据,分析了降雨因素和不同利用方式的土地对水土流失的影响。试验结果表明:在其他影响水土流失因子不变的情况下,土壤侵蚀量与高强度、大降雨量、大侵蚀雨量有密切的关系,总降雨量越大、强度越高、侵蚀雨量越大,其土壤侵蚀量越大;相同降雨条件和相同坡度试验小区的水土流失量由小到大依次为坡篱地种粮、坡篱种茶、荒坡地、坡地种茶、坡篱种柑、土坎篱种柑、坡地种粮、坡地种柑、石坎梯种粮、土坎梯种柑。 |

| Abstract: | This article studied the observation data of runoff and soil erosion in ten runoff experiment plots,which was performed from 2004 to 2008 by water and soil conversation bureau Zhangjiachong watershed in Hubei province,and studied the effect of rainfall factors and different ways of using land on soil erosion.The results showed that soil erosion has close relationship with high strength,great rainfall and great erosion rainfall under the invariable influence factors of soil erosion.The magnitude of soil eros... |
