摘　　要：砒砂岩侵蚀机理是我国北方脆弱生态区治理实践中迫切需要解决的应用基础问题中的难点。为深化理解砒砂岩复合侵蚀发生发展过程、揭示多动力侵蚀交替/耦合关系、辨识复合侵蚀与植被退化的耦合机理,系统总结了国内外对砒砂岩侵蚀研究的主要成果,包括砒砂岩侵蚀类型及其发生动因、砒砂岩侵蚀分布特征、砒砂岩侵蚀岩性机理等,并对现有研究进展进行讨论,指出砒砂岩侵蚀规律研究中面临的关键科学问题,提出未来研究的重点课题,包括砒砂岩区多动力复合侵蚀时空分异规律、复合侵蚀与植被退化的互馈关系、水岩作用下砒砂岩三元结构破坏机理、复合侵蚀试验观测方法等,可为今后开展相关研究工作提供参考。The erosion mechanism of Pisha sandstone has been the basic key problem in the improvement of local ecological environment in North China. In order to better understand the process of Pisha sandstone compound erosion and revelation the relationship between erosion alternate and coupling,study the mechanism of compound erosion and vegetation degradation,the main present research of Pisha sandstone erosion mechanism was well rounded summarized,including the erosion type and mechanism,distribution characteristics of Pisha sandstone erosion,erosion mechanism of Pishan sandstone et al. It discussed the current research,some key scientific issues of the erosion mechanism of Pisha sandstone were pointed out and some significance projects of Pisha sandstone erosion were suggested,including spatio temporal differentiation of Pisha sandstone compound erosion based on multi power,the relationship between compound erosion and vegetation degradation,the break mechanism of Pisha sandstone three-element structure under the water rock interaction and the observation method of the compound erosion experiment. The conclusion could be useful for the correlation research in the future.
