The IPCC’s Fourth Assessment Report was issued in 2007, in which it was pointed out that the precip-itation in many regions in a zone of 30°-85°N was in a remarkable increased trend, but it was in a decrease trend in the low-latitude regions. As a result of global warning, the frequency and intensity of extreme climate events are in an obvious increase trend in many areas. Because of the land-sea thermal contrast and complex topography, the main land of China is subject to drought and flood almost every year. There is no obvious change of annual precipi-tation trend in China, but the regional characteristics of precipitation are significant. The inter-decadal variation of precipitations is closely related to severe drought and flood, and the anomaly of seasonal alternation of atmospheric circulation plays an important role in the occurrence of drought and flood. At the aspect of extreme precipitation, the trend of extreme precipitation in China in recent 50 years was researched by Zhai, et al. The conclusion reveals that extreme precipitation decreased significantly in north China and Sichuan Basin, but increased in west China, the Yangtze River Valley and southeast China. Some other studies suggest that the extreme precipitation days in-creased in northwest China and the middle-lower Yangtze Plain, but decreased in north China and some regions in south China.+++Annual, seasonal, and monthly precipitation can incompletely reflect the local precipitation status. Some re-searches found that the number of rainy days changes asynchronously with precipitation. Recent researches suggest that the annual and seasonal days of precipitation are decreasing significantly along with the decrease of precipitati-on. The researches on precipitation are different on precipitation intensity. Precipitation with different intensities plays an important role in daily life and routine production, so it is quite necessary to analyze the climatic statistical characteristics and variations of precipitation days and precipitation with different intensities.+++Based on the daily precipitation data from 679 stations in China during the period of 1957-2006, some new indexes were defined to analyze the spatial and temporal characteristics of precipitation with different intensities in China. The results are as follows: (1)Proportion of sprinkle in annual precipitation decreases significantly from northwest China to southeast China, but the proportion of sprinkle days in annual precipitation days is the highest; and the contribution rate of moderate precipitation to annual precipitation is relatively stable since recent 50 years, it fluctuates in a range from 20% to 38% , but it is less than 11% in Gansu-Xinjiang and Qinghai-Tibet regions and 11%-16% in other areas; the proportion of heavy precipitation in annual precipitation and the proportion of heavy precipitation days in annual precipitation days increase. (2)Analyses on the trends of annual precipitation and precipitation days reveal that all the sprinkle and moderate precipitation days as well as the annual precipitation in-crease in west China. The most significant increase is found in the eastern Tibet Plateau, while the decrease is de-tected in central and northeast China. (3)The correlation between the number of sprinkle or moderate precipitation days and annual precipitation decreases from the north to the south, but that between heavy rain and annual precip-itation increases. The moderate rain days have increased significantly in Gansu-Xinjiang and Qinghai-Tibet climatic regions since the 1980s and increased in the 1960s respectively, the moderate rain days have decreased in Inner Mongolia climatic region since the 1990s. The heavy rain days in south China have been in an obvious increase trend since the 1970s, and the abrupt change occurred in 1971. The change of annual heavy-rain days is not signif-icant in 4 climate regions including northeast China, north China, southwest China and central China.
