Other Abstract我国东南地区以低山丘陵为主,泥石流活动频率较低,但因经济发达和人口稠密,泥石流易导致严重灾害。东南地区绝大部分泥石流由降水引发,泥石流活动与降水特征间存在紧密的关系。在收集整理了近年来46个泥石流灾害事件后,分析了泥石流活动与各降水气候特征间的关系。分析结果显示,诱发泥石流灾害的5d降水量和15d降水量与降水气候特征间的关系最为密切,其函数关系可用于评估泥石流临界降水量,并作为该区域泥石流区域预报的因子。 
; Low-relief terrain is the main topographical feature in southeastern China.The frequency of debris flow activity is low,but debris flow often induces catastrophic disasters because of developed economy and dense population.The activity of debris flow is closely related to the precipitation characteristics for most of debris flows are induced by rainfall in southeastern China.46 debris flow disaster events in recent years are collected in this paper.The relationship between debris flow activity and precipitation characteristics are analyzed with the rainfall data concerned to inducing these debris flow events and statistic precipitation data.According to the analysis,5 days rainfall and 15 days rainfall are most closely related to the mean rainfall of dry season.The functions of 5 days rainfall and 15 days rainfall with mean rainfall of dry season are available for estimating the critical rainfall of debris flow initiation,and 5 days rainfall and 15 days rainfall can be considered as factors of regional debris flow prediction.
