The research progress and prospect of geological hazards in Southwest China since the 20^th Century

Nearly 30% of geological hazards in China are distributed in Southwest China, which is one of the areas with the most complex causes, the largest number and the most serious disasters in China. In order to better understand the research history and hazard mitigation work of geological hazards in Southwest China, this paper briefly reviews the main process of geological hazard research in Southwest China since the 20th century on the basis of systematically combing the development and distribution law and hazard characteristics of geological hazards in Southwest China. The progress and results are summarized in three main stages. On this basis, the main research trends of geological hazards in Southwest China in the future are prospected, and it is proposed that the research of geological hazards in Southwest China should focus on the high-location and long-distance geological hazard identification technology in high and extremely high mountain areas, the formation mechanism and risk prevention and control of super large geological hazard chain, and the risk dynamic evaluation of big data intelligent mining based on the pregnant background of geological hazards, which can be used as a reference for the research and prevention of geological hazards in Southwest China.
