摘　　要：依据地质灾害发生的动力学机制以及对地表的影响深度和灾害载体的运动特征 ,将广东陆地地质灾害划分为三类灾害系 ,即表层灾害系、表 -浅层灾害系和表 -深层灾害系 ,其影响因素和动力源是大气圈、水圈、岩石圈、生物圈及人文圈 (人类活动 )。五大圈造成了地质灾害系的形成、演化和发展 ,又反过来影响这五大圈的变化。灾害系的能量源归属于三大类 :日地系统、地球系统和人类系统。文中指出人类系统的能量源在地质环境和地质灾害的形成。On the basis of the dynamic mechanism, affect depth of geological hazards and its carrier’s movement, it is suggested that there are 3 types of geological subsystems in the land along the coast of Guangdong Province, i.e. the surface hazard system, the surface shallow hazard system and the surface deep hazard system. The impact factors and the dynamic sources of geological hazards are the aerosphere, hydrosphere, lithosphere, biosphere and human sphere. The cause the formation, evolution and development of geological hazards system, and in turn, affected by the latter. There are 3 kinds of sources of energy for the hazard systems, i.e. the solar earth system, the global system and the human system, respectively. The human factor becomes the most important one in the factors that causes the geological hazards in the coast today.
