Abstract:Because of its complicated tectonics and lithology as well as uneven distribution of the precipitation, Beijing region has developed many geological hazards. Also, there are a number of human engineering activities in the mountain area of Beijing, which will lead to sudden hazards. These sudden hazards are threatening the people and their property safety. Based on remote sensing change detection theory, the authors used the multi-source, multi-temporal domestic satellite data with high resolution to analyze the hazards in Beijing. The authors utilized the remote sensing technology in combination with other methods and means of geographic information systems to analyze the hazards. Among the methods, the authors found that the principal component ratio method is the best. The authors also established the elevation models and the time changing trends model to forecast the degree of danger of geological hazard body in the study area.
