A review of soil erodibility research

Article Summary   by:TsingHua     Original Author: Arid Land Geography
ª
 
Soil erodibility is an important index to evaluate soil sensitivity to erosion.The research on soil erodibility is a crucial tache in understanding the mechanism of soil erosion.Soil erodibility can be evaluated by measuring soil physiochemical properties,scouring experiment,simulated rainfall experiment,plot experiment and wind tunnel experiment.We can use soil erosion model and nomogram to calculate soil erodibility.Many soil erodibility indices and formulae have been put forward in the research of soil erodibility.Soil erodibility is a complex and comparative concept;it is affected by many factors,such as the temporal and spatial change,soil properties and human activities.Some obstacles restrict the research of soil erodibility.Firstly,the research on soil erodibility is mainly focused on farmlands;Secondly,soil erodibility in different areas cannot be compared sufficiently;and thirdly,the research on soil erodibility in water-wind erosion is very scarce.In the prospective research,we should strengthen the research on the mechanism of soil erodibility,conduct research on soil erodibility by both water and wind factors.At the same time,we should reinforce the experimental research on soil erodibility,put observation outdoor and simulative experiment indoor together,combine geostatistics,GIS and remote sensing technology with the soil erosion predicting model,further consummate soil erodibility in the model,predict the erosion quantity accurately,and ascertain the legitimate mode of land use.
