利用清远地区7个气象台站1962—2012年逐日降雨量资料，统计分析了清远地区暴雨天气的气候变化特征，结果表明：清远地区年暴雨日数和暴雨量都呈弱的增加趋势，暴雨强度呈弱的减小趋势。汛期洪涝贡献率高，前汛期比后汛期更容易发生洪涝灾害。年暴雨日数、年暴雨量、暴雨强度和暴雨贡献率地域分布存在明显差异，都呈自北向南递减的趋势，但北部地区均为增加趋势，南部地区均为减少趋势。年暴雨日数和年暴雨量在1969年有一个呈显著增加趋势的突变，但持续年数短。

The climate change characteristics of rainstorm in Qingyuan have been analyzed by using the daily precipitation data of 7 weather stations from 1962 to 2012.The results show that annual rainstorm days and rainstorm amount have weak increasing trend , and rainstorm intensity has a decreasing trend .Flood contribution rate is high in flood season , and flood disaster more easily happen in pre-flood season than later flood season .Differences exist in different regions on the annual rainstorm days , annual rainstorm amount, rainstorm intensity and rainstorm contribution rate , and a decreasing trend exists from north to south;however, the whole shows that an increasing trend is in the northern region , and a decreasing trend is in the southern region .The annual rainstorm days and rainstorm amount had a significant growth but short lasting years remained in 1969.
