| Abstract: | Daily precipitation data during 19 60—2008 of 17 national stations in Jiangxi province are used to study extreme precipitation with daily rainfall above absolute thresholds（25 mm and 50 mm）or relative thresholds（95% and 99%）. The results show that the frequency of extreme precipitations increased in most part of the province,and the intensity of extreme precipitations reduced around Poyang Plain area,while increased in most of the other area. |
