Abstract

Dunhuang Yangguan in the south of Qilian Mountain, where the flood season comes from the floods of Subei, Aksai and the local floods every year, it had a disastrous floods in 2~3 years, meanwhile, the flood carrying debris flow to polluted the unique survival local water sources and caused the serious damage of water resources. Sub-daily rainfall extremes may be associated with flash flooding, particularly in mountain regions, but compared with extremes on daily timescales, they have been relatively little studied in mountain regions. In the recent decade, extreme precipitation events have let to numerous flash floods in and around the Duhuang region. Based on the daily precipitation data from 1958 to 2015 (the weather station of Qilian data from 1958 to 2013) of six weather stations in Dunhuang neighborhood, that is, Mazongshan, Dunhuang, Guazhou, Jiuquan, Yumen and Qilian, period characteristics and spatial characteristics of extreme precipitation events were analyzed by the Manner-Kendall mutation test, wavelet analysis and kriging interpolation in Dunhuang area which can provide the basis for water resources management and flood control and disaster reduction. The results indicated that the frequencies of extreme precipitation in Dunhuang, Guazhou, Jiuquan, Yumen and Qilian are all increasing in addition to the decreasing trend of Mazongshan. The annual rainfall increments of extreme precipitation are -0.063, 0.127, 0.072, 0.138, 0.104 and 0.638 d·(10a)-1, respectively. In the extreme precipitation intensity mutation analysis, the UF statistic showed the trend of "V" type, namely, the trend of increasing first and then decreasing, The control periods of extreme precipitation intensity have 53-year, 22-year, 36-year, 56-year and 58-year time scale in Dunhuang, Guazhou, Jiuquan, Mazongshan, Yumen and Qilian according to the result of the extreme precipitation intensity wavelet analysis. Daily maximum precipitation, extreme precipitation and extreme precipitation intensity show the spatial distribution characteristics of gradient from west to east.
