磁性示踪条件下坡面土壤侵蚀产流、产沙及侵蚀空间分异特征
Runoff and Sediment Yield and Spatial Variation of Soil Erosion Slope Under Magnetic Tracing Condition
摘要
Abstract
Under simulated rainfall condition,the runoff and sediment yield and spatial variation of 10 degree,15 degree and 20 degree slopes,on which magnetic tracers were placed,were determined.The results showed that,with the increase of the slope degree,the runoff and sediment yield of slopes increased,and the time when the runoff and sediment yield reached stable states were later in the process of rainfall.Soil magnetic susceptibility decreased extent of the top part of the 10 degree slope was the greatest,and the middle part was greater than that in the foot part of the slope.Nevertheless,comparing with the 10 degree slope,the slope magnetic susceptibility trend was changed with the increase of the slope degree.The magnetic susceptibility decreased extents of the foot part of the slopes（15 degree and 20 degree slopes） were the greatest among that of the three parts of the slope.The variation of magnetic susceptibility showed that erosion intensity of the top part of the 10 degree slope was the greatest.However,soil erosion intensity of the foot part of 15 degree and 20 degree slopes increased.关键词
