Abstract: On the basis of 296 st ations with com plete daily precipitation records during 1951-1995, this paper mainly studied extreme changes of precipitation amount, precipitation frequency, and precipitation intensity in China. The results revealed that there are no obvious trends in annual precipitation, 1-day and 3-day maximum precipitation, and precipitation amount for daily precipitation above different intensities. However, a significant increasing trend in extremely above normal meanint ensity of precipitation in China is accompanied with reduction of rain days. Regional difference is very evident in the trends of China's precipit ation extremes. In eastern China, much above normal mean intensity of precipitation tends to increase. In North China, under the backgr ound of decrease in annual precipitation to tals, decreasing trends are very obvious for 1-day and 3-day maximum precipitation, and for rain days with daily precipitation above 50 mm and 100 mm. However, annual mean intensity of precipitation still tends to increase in North China. Exception is in western North west China, where the annual precipitation amount displayed an increasing trend and the area coverage of extreme amount of high intensity precipitation displayed an increasing trend but it showed no significant trend for wetdays.
