气象地质灾害降水阈值分析——以若尔盖地区为例

Analysis of Precipitation Threshold of Meteorological and Geological Disasters——A Case Study of Zoige Area

自然或人为因素都将诱发地质灾害的发生,其中降水是诱发地质灾害的自然因素之一,为减少若尔盖地区地质灾害对人民生命健康与财产安全的威胁,该文选取2007—2020年四川若尔盖地面常规气象观测站逐日降水资料、24个自动观测逐时的降水资料、若尔盖地区地质灾害灾情信息统计资料,运用统计分析方法,分析若尔盖地区地质灾害降水阈值。

Both natural and human factors will induce geological disasters,among which precipitation is one of the natural factors.In order to reduce the threat of geological disasters to people’s life,health and property safety in Zoige area,this paper selects the daily precipitation data of Zoige surface conventional meteorological observation station in Sichuan from 2007 to 2020 and the hourly precipitation data of 24 automatic observations.According to the statistical data of geological disaster information in Zoige area,the precipitation threshold of geological disaster in Zoige area is analyzed by using statistical analysis method.
