摘　　要：[目的]分析河南省两千年干旱灾害的运气特征及周期规律。[方法]基于河南省公元前221年至公元1840年干旱灾害数据,进行旱灾等级划分,利用统计学工具和小波分析方法,探究河南省不同运气时段的旱灾频次差异及周期性变化规律。[结果]河南省旱灾发生频次最多的主气时段为四之气(太阴湿土)(P<0.001),最多司天时段为厥阴风木、少阴君火(P<0.05),最多在泉时段为少阳相火(P<0.05)。在多时间尺度下,河南省干旱灾害共有4个准周期,第一至第四准周期分别是510、690、300和150年。[结论]不同主气、司天、在泉时段河南省不同等级干旱发生频次具有显著差异,与运气理论具有一定的吻合性;同时河南省干旱灾害发生具有一定的周期特征。[ObjectiveObjective]To analyze the Yunqi characteristics and periodicity of drought disasters in He’nan Province during 2000 years.[MethodsMethods]On the foundation of the drought data of He’nan Province from 221 BC to 1840 AD,a hierarchical classification was conducted,using statistical tools and wavelet analysis to explore the frequency and periodicity of drought in different Yunqi periods.[ResultsResults]The most frequent dominant Qi period of drought in He’nan Province was 4th Qi(Taiyin Shitu)(P<0.001),the most of Sitian period was Jueyin Fengmu and Shaoyin Junhuo(P<0.05),the most of Zaiquan period was Shaoyang Xianghuo(P<0.05).At multiple time scales,drought disasters in He’nan Province had 4 quasi-cycles,the 1st to the 4th quasi-cycles were 510,690,300 and 150 years,respectively.[ConclusionConclusion]There was a significant difference in the frequency of drought levels in He’nan Province in different periods of dominant Qi,Sitian period and Zaiquan period,which was partly consistent with the Yunqi theory.Besides,the drought disaster in He’nan Province had certain periodic characteristics.
