Abstract
Using the precipitation data of 35 meteorological stations in Huaihe River Basin, SPI is applied to analyze annual drought index of nearly 50 years (1961-2010). The results show that the frequency of drought in Huaihe River Basin reduced and the intensity of drought increased at the beginning of 21st Century, but drought areas decreased; main drought type is mild-medium drought, severe drought rarely occurred; in the current situation of climate change, the negative impact of drought on agricultural production will be lowered in Huaihe River Basin.
