Research Progress of Soil Compound Erosion in Black Soil Region of Northeast China
Soil compound erosion is the erosion phenomenon occurring under the interaction or coupling action of two or more erosion exogenic forces.The complex erosion of multiple forces in the black soil area of Northeast China has the characteristics of spatiotemporal alternation and superposition.In recent years,some progress in the study of soil composite erosion in black soil areas had been made in terms of the mechanism of occurrence and the effect on soil degradation.Based on previous research results,the mechanism and research methods of soil erosion by water or wind under freezing and thawing,combined erosion of tillage and hydraulic,combined erosion of water and wind and multiple forces compound erosion were systematically summarized.The main problems in the research were concluded and the key scientific problems to be solved in the future research of composite erosion mechanism and simulation test method,as well as the experimental simulation technology and quantitative evaluation method that should be paid attention to,were put forward,which could provide reference for the future research of soil composite erosion in the black soil region of Northeast China.
