Urbanization is a common development trend of countries all over the world, which is a mark of civilization and progress of human beings. The number of urbanization-induced environmental geological hazards has grown steadily in recent years and is receiving increased attention throughout the world. The purpose of this paper is to generalize China's urbanization process and induced environmental geological hazards. Driving forces and characteristics of urbanization are briefly introduced in this study; specifically, the distribution of urban agglomerations is principally related to water resources, transportation and energy. Common geological hazards and particular ones in mountain city, mining city and coastal city are also summarized. The type and severity of hazards are different due to the differences of natural conditions and various urban functions. Main environmental geological hazards in cities are land subsidence, landslide and seawater intrusion, etc. Accordingly, reasons for these urbanization-induced geological hazards in different type of cities are analyzed and discussed. The research results may provide a clear perspective for urban geological hazard prevention, and suggestions for urban geological hazard control are pointed out.
