Abstract:: Based on the daily precipitation and rainstorm days of eight national meteorological stations in the middle and upper reaches of the Dongjiang River from 1965 to 2017, linear trend method, correlation analysis method, Mann-Kendall mutation test, sliding t test, Morlet wavelet analysis were used to analyze the time and space characteristics of precipitation and rainstorm days in the middle and upper reaches of the Dongjiang River. The results show that the precipitation and rainstorm days in the middle, upper flood season and the first flood season of Dongjiang River present no significant decrease trend, and the precipitation in the annual and post-flood seasons and the number of rainstorm days do not increase significantly; the annual, flood season, front (back) flood season precipitation and the number of rainstorm days more distribute in the southwest and more in the northeast. The flood season is the concentrated period of precipitation and heavy rain, and there are more pre-flood periods and less post-squat periods. The floods in the flood season had mutations in 1972, 1986 and 2007, and precipitation in the first flood season. Mutation occurred in 1971 and 2005, and there was no mutation in the post-rhodium precipitation. The number of rainstorm days in the flood season occurred in 2003 and around 2008. The number of rainstorm days in the first flood season changed in 1972 and around 2004. The number of rainstorm days in the flood season changed before and after 2011. The annual precipitation was 2 years, 4~5 years and 8~10 years. oscillation period during the 10 years, the number of annual rainstorm days has the 2~4 years, 5~6 years, and 8~10 years period, which has a good correspondence with the annual precipitation period.
