The Application Progress on Research Methods of Landslide Chronology
摘要
Abstract
The study on landslide chronology is important for the formation and development, the prediction and warning systems and the risk assessment of landslide hazard.In order to do a comparative analysis of every landslide dating new technologies, the recent application advances on landslide dating both at home and abroad are summarized.Various technologies of landslide dating, such as 14 C, OSL, Cosmogenic nuclides, tree-ring and li-chenometry of dating, are discussed and analyzed in detail.The merits and demerits of various technologies and practical problem of landslide dating are discussed and corresponding solutions are given.It is indicated in the con-clusion that research projects of 14 C, OSL, Cosmogenic nuclides have been well studied, but projects of tree-ring and lichenometry relatively less.Much of the research in the world are focused in Europe, North America and East Asia, etc, however, few in China.The domestic studies are mostly focused in the Upper Yellow River and the Three Gorges area.The researches of landslide chronology are just beginning and have great capabilities and scien-tific importance in China.To the Midwest, especially the Qinghai-Tibet Plateau and the Loess Plateau, the studies of landslide chronology have great practical significance for the disaster prevention and mitigation and the socioeco-nomic development.关键词
