Based on daily precipitation data of 53meteorological stations over the North China Plain during 1961-2010,the extreme precipitation thresholds were determined for different stations by centesimal value method.Then,the three indices of annual amount,frequency and intensity of extreme precipitation events were counted and their spatial characteristics and temporary trends were analyzed.Results showed that most stations in the North China Plain had no significant monotonic trend by each selected index of extreme precipitation events and however,the annual amount,frequency and intensity tended to reduce.Furthermore,the variation trends of extreme precipitation events exhibited similar spatial variability.Specifically,there was a positive trend of extreme precipitation events in Hebei Province and the southeast coast of Shandong Province,while a negative trend,in He'nan Province.Each index fluctuated during 1961-2010,and basically showed a significantly decreasing trend in the 1960s.The annual amount and frequency showed abrupt changes around the year of 1965.However,the intensity did not show an abrupt change.
