【Abstract】 This paper was based on the province’s rainfall data that were gathered from 85 meteorological stations from 1961-1980 , with the reference to the rainfall records from 1951-1980.The characteristics and regularity of the rainfall were also discussed from the viewpoint of climatology.The data analysis showed that the province had an abundant rainfall with a larger distribution in the. east and west mountainous ranges than in the rivers valleys. The rainfall also varied with seasons giving 48% of the rainfall being concentrated in April , May and June. The analysis farther showed a marked fluctuation of the monthly rainfall from year to year and frequent occurrence of the rain gush leading to a constant drought or flooding every a few years which therefore affected the province’s agricultural production to a certain extent.更多还原
