Influence of Vegetation Filter Strip on Slope Runoff, Sediment Yield and Nutrient Loss

چکیده
It is an important branch of erosion research to control soil on eroded gullies and slopes by using vegetation filter strip. Several simulated rainfall experiments were carried out in tanks filled with loess sandy loam taken from a typical gully area less coverage Yanghe hilly basin Xuanhua District, Zhangjiakou City, Hebei Province. The water conservation effects two different setting modes compared under the same strip width intensities slopes. During process, changes runoff sediment yield nutrient loss not stable, but index had similar variation trends combinations intensity, slope coverage. Multiple regression results showed that production can be effectively reduced through strips, which are jointly affected intensity slope. There was no significant difference amount between modes. Rainfall gradient strengths impact loss. Through cluster analysis, impacts equal or offset. In general, strips offset slope, regulation obvious extreme steep conditions. What’s more, dominant effect erosion. this may provide reference for practical application

Effect of natural land covers on runoff and soil loss at the hill slope scale
Erosion plots were selected for characterizing the effects of main natural factors on runoff and soil loss in a semi-arid region. These erosion plots with an area of 40 m2 are located in the Kakhk experimental watershed in Gonabad County of Khorasan-e Razave Province in the north-eastern Iran. Data acquired from 2008 to 2015 include slope, aspect, soil texture and land covers (canopy...
