中文摘要: 利用武汉、荆州、宜昌、陨县、恩施5个代表站的旱涝等级资料,建立了湖北省1470～2000年( 531年)的旱涝等级序列,并分析了旱涝变化特征。分析认为,近531年中,湖北省涝灾比旱灾多88%,大涝约48年一遇,大旱约59年一遇;旱期长于涝期;20世纪是旱涝灾害最多的一个世纪,19世纪上半叶是最湿润的50年;各世纪旱涝变化周期不尽相同,主要变化周期为20年、10～11年、5～6年。

Abstract:Based on the data of Wuhan,Jingzhou,Yichang,Yunxian,Enshi,a drought/flood grade series of Hubei province in the period of 1470—2000 is established.The variation of drought/flood is analyzed.It demonstrated that,in the last 531 years,there're 8.8% more floods than droughts in Hubei province.The recurring period of serious flood was 48 years and that of serious drought was 59 years,and the lasting period of drought was longer than flood. And the 20th century was a century that there were the most drought and flood disasters within the period of 1470—2000,and the first half of 19th century was the most wet period of 50 years.The transformation periods in different centuries were different,and the major periods were 20-,10-11-and 5-6-year.
