Abstract Based on the daily precipitation data of each county,city and district in Lishui from 1971 to 2020,the temporal and spatial distribution characteristics and evolution trend of night rain precipitation from 20:00 to 08:00 were analyzed by using multi-scale trend analysis method in order to serve agricultural production.The results show that although the precipitation in Lishui is less in winter half year,the proportion of night rain is larger,especially in January.The night rain rate is high in the middle east of space,and the highest in January in Yunhe.The summer precipitation is obvious,but the proportion of night rain is small,especially in July.The night rain rate is low in the north of space and the lowest in January in Suichang.
