How root and soil properties affect soil detachment capacity in different grass–shrub plots: A flume experiment

In the four plots of Caragana korshinskii and Agropyron cristatum, Caragana korshinskii and Bothriochloa ischaemum, Caragana korshinskii and Artemisia gmelinii and Caragana korshinskii, the soil detachment rate at 50 cm from the shrub base was lower than that at the shrub base. In different locations of the same shrub, the influence of root length on soil detachment rate is different. In a single Caragana korshinskii sample plot, under the same root length density, the root length at the base of the shrub has a relatively high ability to reduce the soil detachment rate. In the other sample plots, under the same root length density, the root length at the base of the shrub has a relatively low ability to reduce the soil detachment rate.
