摘要
土壤复合侵蚀是在2种及以上侵蚀营力交互作用或耦合作用下发生的侵蚀现象。东北黑土区多营力复合侵蚀具有时空交替和叠加的特征。近年来,黑土区土壤复合侵蚀研究在发生机理及对土壤退化的作用等方面取得了一定的进展。基于前人研究成果,系统总结了冻融作用下的土壤水蚀或风蚀、耕作与水力复合侵蚀、风水复合侵蚀以及多营力复合侵蚀在发生机理和研究方法等方面的研究现状,归纳了研究中存在的主要问题,提出了今后在复合侵蚀机制与模拟试验方法等研究中需要解决的关键科学问题以及应关注的试验模拟技术、定量评估方法,以期为未来东北黑土区土壤复合侵蚀研究提供参考。
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.
