Abstract

Based on the data analysis and field investigation, the spatial distribution characteristics of geological hazards in the south urban agglomeration of Chengdu-Chongqing Economic Zone are compared and analyzed. Study result shows that both of the formation conditions (topography, geological structure, lithology) and triggering condition (rainfall, seismic activity, human engineering activities) vary significantly from south to north, from west to East, leading to great difference of spatial distribution and characteristics of geological hazards. In the west part, the formation factors such as lithology and geological structure are very complex, the topography undulates greatly, and the seismic activity is frequent. As a result, the geological hazards take on the characteristics of larger magnitude, more debris flows, and linear distribution along the river and tectonic. In the south part, due to the wide distribution of carbonate rocks and intense mining activity, ground collapse becomes the main type of geological hazard. As far as the north part is concerned, the geological and lithology are simple and the terrain is flat, but the human engineering activities are the most intense of the urban agglomeration of south Sichuan Province, simpler type, larger quantity, smaller scale, wide distribution compose the main features of the geological hazards in this part.
