Abstract: Based on the monthly precipitation and runoff data in Mabie river basin during 1982—2015, the characteristic and variation of hydrological and meteorological drought are analyzedby using standardized rainfall index （SPI） and standardized runoff index （SRI）, and then the correlation between meteorology and hydrological drought are explored. The results show that different degrees of drought occurred every 2~3 years in the Mabie river basin during 1982—2015. The trend of meteorological drought is not significant at the annual scale. At the seasonal scale, the trend of meteorological drought in autumn increases significantly, and the trend of drought in spring, summer and winter is not significant. At the annual scale, hydrological drought has a significant increase trend. After 2000, the frequency of hydrological drought increases significantly, and the number of drought years accounts for 70% of the number of hydrological drought years from 1982 to 2015. There is a close correlation and time-delay relationship to some extent between meteorology and hydrological drought in the Mabie river basin. Among the time scales of 1, 3, 6 and 12 months, the correlation between SPI₁₂ and SRI₁₂ is the best at 12 months, and the correlation coefficient between the SPI₁₂ and the SRI₁₂ of one-month lag is the largest, indicating that the occurrence of a hydrological drought lagged behind the meteorological drought for one month.
