Abstract:: Based on the daily precipitation data for 81 stations of Guizhou Province from 1961 to 2012, the analysis techniques such as probability distribution, linear trend, spatial analysis were used to analyze the maximum daily precipitation in time and space for recent 52 years. The results showed that maximum daily precipitation presented the increasing trend with the rate of 2.3 mm/decade. The extreme maximum daily precipitation was 336.7 mm, and the average maximum daily precipitation was 205.1 mm, the annual variation tendency showed that the maximum daily precipitation had decreased since 2000. The maximum daily precipitation showed obvious seasonal variations and increased from north to south, and the maximum daily precipitation decreased in spring and autumn, and increased in summer and winter. Furthermore, the recurrence periods of 100 years, 200 years of the maximum daily precipitation intensity were estimated primarily, which seemed that their distribution trends were consistent. The maximum area can be found in the south range. The maximum daily precipitation intensities in 100 years and 200 years can reach to 350.9 mm and 375.8 mm in Guizhou Province.
