Abstract:: 30 years’ precipitation data of 76 observation stations which distributed in three climatic zones: the temperate, warm temperate, and northern subtropics were collected to analyze the maximum, minimum, mean value as well as the linear trend of the mean value for the yearly, flooding-season precipitation and precipitation of each month in the flooding season, and to analyze the precipitation characteristics in each stage by dividing 1980 to 2009 into three stages in terms of the interal of a decade. The results showed: (1) all the average precipitation of the year, and flooding season and each month in the flooding season decreased progressively from southeast to northwest, and the ratio of flooding-season precipitation and the yearly precipitation in the warm temperate zone reached up to 73%; (2) among the 1980s, 1990s, 2000s, the average precipitation of the year and flooding season decreased first and then increased. In 1980s, the average precipitation increased linearly in mid temperate zone and decreased in the warm temperate and northern subtropical zones. The average precipitation decreased linearly in 1990s, while increased in 2000s in all three zones. During the whole period, the average precipitation in mid temperate zone increased linearly at a small rate of 5.9 mm/10 a; the average precipitation in the temperate and northern subtropical zones decreased linearly at the ratio of -23.7 mm/10 a and -60.4 mm/10 a, respectively.
