摘要
对国内外冻融侵蚀研究的主要成果进行了介绍。首先探讨并明晰了冻融侵蚀的概念;介绍并分析了冻融侵蚀的成因、分类及侵蚀强度分级标准、冻融侵蚀量及其主要影响因素、冻融侵蚀预报和冻融侵蚀的防治等研究成果,指出了冻融侵蚀研究中存在的问题与不足;最后,结合我国冻融侵蚀研究的实际情况,提出了今后一定时期内,我国未来冻融侵蚀研究的方向与重点领域。
Main advances at home and abroad in the field of freeze-thaw-induced erosion are reviewed.The notion of freeze-thaw-indued erosion is firstly discussed and clarified.Then some research results such as the cause,type,intensity classification,erosion rate,main influence factors,erosion prediction and prevention and control of freeze-thaw erosion are presented and analyzed.The problems and shortcomings of current freeze-thaw-induced erosion research are pointed out.Research directions and key issues of freeze-thaw-induced erosion in a certain period of the future are finally put forward in terms of the real research situations of freeze-thaw-induced erosion in China.
