Based on the monitoring data of 36 meteorological stations in Jiangxi Province from 1960 to 2018, the characteristics of drought change and the correlation between SPEI index and M-K trend test. The results show that the SPEI-12 index showed a slight downward trend, and drought and flood alternated from year to year. The annual drought mainly distributed in the northeast, west and southeast of Jiangxi Province, and most of the drought was global and regional, and the regional drought was more significant after 2000. The seasonal drought occurred in summer and autumn, especially in autumn. The drought degree in spring and winter was light and more frequent in the southern part of Ganzhou. However, after 2001, spring showed an aridity trend, and the SPEI index in summer, autumn and winter showed an upward trend, even easy to cover the province's serious autumn drought. Crop to the affected area and summer and autumn were significantly correlated with SPEI index and summer drought influence on Jiangxi crops than autumn drought. The results can provide reference for drought control and drought resistance in Jiangxi Province.
