摘要
高海拔寒区环境特殊,在全球气候变暖和人为活动加剧等因素的影响下,高海拔寒区日益严重的水土流失给牧区人民生产生活和生态环境带来严重影响。对高海拔寒区主要的土壤侵蚀类型——冻融侵蚀的概念,高海拔寒区冻融侵蚀的主要类型——冰川侵蚀、融冰/雪径流侵蚀、冻融风蚀、冻融泻溜、冻融泥流和沟道冻融侵蚀的形成特点及驱动力进行了分析,以期为高海拔寒区冻融侵蚀研究提供参考。
The environment of frigid zone is special.Under the conditions of global climate warming and aggravation of human activities,the increasingly serious soil and water loss of frigid zone has seriously affected the people's production and life of pastoral area.The paper analyzed the concept of freeze-thaw erosion,the main type of soil erosion of frigid zone,the formation characteristics and driving forces of the main types of freeze-thaw erosion of frigid zone,including glacial erosion,thawing/snow runoff erosion,freezing-thawing wind erosion,freeze-thaw slipping,freeze-thaw mudflow and gully freeze-thaw erosion for providing references for studying the freeze-thaw erosion of frigid zone.
