【Objective】 Entropy was used to investigate the spatial and temporal variability of precipitation in Shiyang River Basin to provide a basis for rational development of water resources in the basin.【Method】 Marginal entropy was used to investigate the variability of precipitation associated with monthly,seasonal and annual time series.Also,apportionment and intensity entropy were used to investigate the intra-annual and decadal distributions of monthly and annual precipitation amounts and numbers of rainy days within a year and decade respectively.Based on the data of daily precipitation from eight weather stations in the Shiyang River Basin from 1959 to 2008,an entroy-based theory spatial and temporal variability of precipitation time series were employed to investigate the basin.【Result】 The results show that there is both spatial and temporal variability of precipitation in the Shiyang River Basin.The temporal variability of annual series seems to be less than that of individual seasonal series,and seasonal time series seems to be less than the corresponding month.The winter variability contributes more to the variability of annual time series,whereas summer contributes less to the annual variability.The months having high variability for different seasons are March in Spring,June in Summer,November in Autumn and December in Winter.The variability of precipitation amounts within a year is found to be high during the year of 1966,1979,1984,1987 and 1993,and the variability of rainy days within a year is found to be high during the year of 1973,1976,1984,1987,2001 and 2007.The spatial variability of precipitation amounts seems to be basically the same as the number of rainfall days.It increases from southeast to northwest of Shiyang River Basin.【Conclusion】 Entropy considers the spatial and temporal variability of precipitation comprehensively,which can effectively solve the problem of spatial and temporal variability of precipitation.
