【 摘 要 】

With the development of remote sensing, satellite positioning and big data integration technologies, the application of geographic information in various stages of disaster response has been promoted. In this paper, the application of geographic information in disaster collection, assessment and trend is introduced according to the characteristics of China's geographic topography, and the geological disaster is then taken as the research object the trend of secondary disaster (i.e.,landslide and barrier lakes) after the occurrence of earthquake by geographic information technology. Specifically, the positioning of public opinion information and extraction technology and the professional information of disaster factors stack technology are integrated into the data layer of the information system to analyze the trend in detail by combining with the mathematical model, which is of great significance for future geological disaster response and rescue.
