摘要
和龙市境内发育各类地质灾害隐患点共计234处,对当地居民的生命及财产安全形成了严重威胁。通过研究和龙市地质灾害的发育特征,掌握了其主要地质灾害隐患点的数量、类型以及分布规律和威胁对象。根据5项分区原则,并结合分区界线划分结果,将和龙市划分为4类地质灾害易发区,分别为地质灾害高易发区、地质灾害中易发区、地质灾害低易发区和地质灾害非易发区。
There are 234 hidden danger points of various geological hazards in Helong City, which pose a serious threat to the lives and properties safety of local residents. By studying the development characteristics of geological hazards, we obtained the quantities, types, distribution rules, and threatened objects of hidden danger points of the main geological hazards in Helong City. According to the five zoning principles of geological hazard susceptibility degree and the result of division boundary, we divided the geological hazard prone areas in Helong City into four categories, which are high-, middle-, low- and non-susceptible areas respectively. The zoning evaluation could provide a basis for reasonable arrangement of geological hazard prevention in Helong City in future.
