摘要
延平区是福建省地质灾害易发区,降雨是灾害最重要的诱发因素。系统分析了区内降雨类型对地质灾害的影响,历年灾害、2010年重大地质灾害与降雨的相关性,总结了地质灾害临界降雨量的影响因素。进行了地质灾害临界降雨量的区划,将全区分为四个区,给定各分区的预报、预警和警报等三种状态下的临界降雨量,为区域防灾减灾提供了基础数据和科学依据。
Yanping district in Fujian province is a geological zone where geological hazards occur very easily,and the most important factor is rainfall. This paper analyzed the impact of the type of rainfall to geological hazards. It analyzed the correlation between geological hazards and rainfall over the years,especially in 2010. This paper divided the critical rainfall of geological hazard into four areas and gave the critical rainfall of each partition in the forecast state,early warning state and alert state. The result could provid basic data and scientific basis for the regional disaster prevention and mitigation.
