摘　　要：南方第四纪红土沉积是揭示该地区古环境变迁的良好信息载体,红土发育与构造变动、季风演化存在耦合.就第四纪红粘土的研究进展作了回顾,认为红土形成时代、成因、网纹化机制等方面的争议制约了红土地层学的发展,系统研究红土的沉积学、年代学、土壤学、生物气候学、地球化学特征,可以推动红土地层学的发展,并丰富全球变化的内容.The red earth sediment in Quaternary is an imp or tant carrier with the paleoenvironmental changes information in South China, the research history shows that there exists mechanism coupling between red earth′ s development and local tectonic processes and monsoon′s evolvement in Eastern Asia. However, there are still some different opinions about its age, cause of f ormation, magnetic characteristic, vermiculated mechanism, and so on, which has restricted the progress of red earth stratigraphy. By reviewing some research fi ndings of red earth, it was pointed out that it would be basic premise to wholly study on the characteristics including sediment, chronology, pedology, phenolog y, geochemistry, which would promote the development of red earth′s stratigrap hy.
