    • The daily precipitation observational data of 740 stations from 1960a to 2000a Which provided by National Climate Center of Chinese Meteorologial Administration, are divided in sections and statistically analyzed. A common feature is revealed——the power-law distribution, and different precipitation corresponds to different power-law exponent; this to a certain extent reflects that different precipitation have different climate backgrounds and control systems. The power-law exponents of the seven climate regions of China show the trend of increase from southeast to northwest, this corresponds to the spatial characteristic of precipitation of China——more in east and less in west, more in south and less in north. The analysis on the characteristic of the temporal evolvement of the power-law exponent shows that the abruption points of the power-law exponent of northeast, east, and northwest of China correspond to the drying trend of northern China starting from 1970s.
