Research on Serious Geological Disaster Rapid Emergency Response of Fujian Province
[Purposes]Geological disaster monitoring research is of great significance to disaster preven-tion and mitigation services,road network planning,urban construction and other decisions,so it needs to be studied.[Methods]Taking the traffic trunk line from Nanping to Minqing section of G316 national highway with frequent geological disasters as the demonstration area,advanced technical means such as airborne radar and low-altitude photogrammetry were used to collect and process high-resolution ortho-images and digital elevation models of geological disaster bodies in the demonstration area,and com-bined with multivariate remote sensing information,the spatial morphological characteristics of geologi-cal disaster bodies were interpreted.[Findings]The digital three-dimensional visual basic information of geological disasters such as landslide and collapse was established.[Conclusions]The study can pro-vide services for future periodic inspection,evaluation,monitoring,rapid emergency response and safety risk elimination of sudden geological disasters.
