城镇化是世界各国共同发展趋势，是人类文明进步的标志。近年来，城市化引发的环境地质灾害数量稳步增长，日益受到世界各国的关注。本文的目的是概括中国城市化进程及其引发的环境地质灾害。本研究简要介绍了城镇化的驱动力和特征；具体来看，城市群的分布主要与水资源、交通、能源有关。总结了山地城市、矿区城市、沿海城市的常见地质灾害和特殊地质灾害。由于自然条件和不同城市功能的差异，灾害的类型和严重程度也不同。城市主要环境地质灾害有地面沉降、滑坡和海水入侵等。据此，对不同类型城市中城市化引发的地质灾害产生的原因进行了分析和探讨。研究成果可为城市地质灾害防治提供清晰的视角，并为城市地质灾害防治提出建议。
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.
