In order to reduce economic and social loss caused by drought disaster
this paper judged the trend of drought in Guangxi based on commensurability and symmetry principle. The results showed: ① The drought disaster in Guangxi showed good commensurability
and time symmetry was very distinct. ② The butterfly structure diagram and commensurability structure system indicated a strong signal of drought disaster occurred in 2017 in Guangxi. ③ ENSO events showed a good correlation with the occurrence of drought disaster. ④ The drought disaster usually appeared in the upward section of sunspots number when the solar activity was in its accelerating stage.
