- Abstract:
-
The standardized precipitation evapotranspiration index (SPEI) and runoff drought index (SDI) were used to examine spatial and temporal evolution characteristics of meteorological drought and hydrological drought in the Sanjiang Plain in the past 50 years. We collected data from 1961 to 2010 in 6 meteorological stations and 4 hydrological stations in the study area. The results showed that: (1) meteorological drought was frequent during the period 1970—1980 and period 2000—2010; the wet tendency in spring and winter occurred in most parts of Sanjiang Plain from a seasonal perspective; however, there was a non-significant dry tendency in summer and autumn in the study area; (2) in the late 1960s, 1974—1981 and 1999—2010, a longer and more intense hydrologic drought occurred; the hydrological drought intensity in the downstream was more serious than that in the upper stream; (3) hydrological drought had 1~7 months lag to meteorological drought; the time lag prolonged with the increase of the time scale. This study can provide the reference for drought management and integrated water resources management in Sanjiang Plain.
