摘　　要：地质灾害易发区和危险区是根据地质灾害发育程度、分布规律,将地质灾害类型相同,发育条件相近,易发和危险程度相似或接近划分为同一区块。在对某一地区地质灾害进行预防或治理之前必须对其特征进行分析和研究。对地质灾害区划及分区特征的研究往往决定着后续工作的开展及布置。在划分出高易发区和高危险区的基础上,进一步划分出研究区的重点地段,这对制订研究区的地质灾害防治规划具有非常重要的现实意义。文章通过对广东省紫金县地质灾害区划特点及分区评述为例,对地质灾害区划及分区进行归纳总结,希望以此为该地区地质灾害预防与治理提供一些指导作用。according to the development degree and distribution law of geological hazards,the prone and dangerous areas are divided into the same block with the same types of geological hazards,similar development conditions,and similar risk degree.It is necessary to analyze and study the characteristics of geological disasters before the prevention or management of geological disasters in a certain area.On the basis of dividing the high risk area and the high risk area,the key sections of the research area are further divided,which is of great practical significance to the planning of geological disaster prevention and control in the research area.Based on the characteristics and zoning of geological disaster in zijin county,guangdong province,this paper summarizes the zoning and zoning of geological disaster,hoping to provide some guidance for the prevention and management of geological disaster in this area.
