On the basis of calculating the monthly SPEI values of the Beijing-Tianjin-Hebei region from 1961 to 2015, the spatial-temporal gathering characteristics and change trends of different degrees of drought events were explored using the SaTScan spatial-temporal scanning software. The results showed that the frequency of drought in the Beijing-Tianjin-Hebei region continued to increase from 1961 to 2015, and the degree of drought continued to intensify. The spatial-temporal gathering characteristics of light drought and moderate drought are similar to that of total drought, and they mainly occur in Shijiazhuang, Baoding, Hengshui and Xingtai cities. The spatial-temporal gathering characteristics of severe drought and extreme drought are similar, and they occur mainly in Langfang, Baoding, Cangzhou and Shijiazhuang cities. From 1961 to 1993, the gathering state of drought remained stable. After 1994, the spatial fluctuation of drought gathering increased, and the gathering range and degree were enhanced. With the aggravation of drought, the difficulty of drought gathering occurrence increases, the difference of gathering range increases, and the spatial volatility and unpredictability are enhanced.
