Abstract: In recent years, under the influence of human social and economic activities in the process of global warming and urban expansion, the frequency of sudden and local geological disasters have increased significantly in Qinghai Province. In order to actively respond to the severe situation of geological disasters, guarantee the safety of people's lives and production, consolidate the results of disaster reduction and scientific and reasonable response measures are proposed. This paper takes the landslide and debris flow disasters in Qinghai Province from 1990 to 2019 as the research object. Through mathematical statistics, the development characteristics, temporal and spatial distribution patterns and main triggering factors of landslides and debris flows in Qinghai Province in the past 30 years are analyzed and studied. The results show that: ①The scale of disasters is mostly small, and the disaster types are mainly landslides. ②In terms of time, it mostly occurred from May to October; in terms of space, it mainly occurred in Xining City and Haidong City in the Qingdong region with complex terrain. ③Rainfall and excavation slopes are the main triggers. ④In recent years, the increase trend of landslide, rockfall and debris flow disasters is obvious. The results of the research will provide guidance and reference for the geological disaster prevention work in Qinghai Province for a period of time in the future.
