摘　　要：为了揭示我国燥湿邪气异常分布及病理意义,利用全国1951-2005年逐日相对湿度等实测资料,采用EOF、REOF和小波分析等数理方法。研究表明:1)我国燥湿异常存在哈尔滨区域、广州区域、北京区域、西安区域和乌鲁木齐区域等5类高相关典型区;2)燥湿变化,由南向北和由东向西愈趋杂乱、变化幅度加剧,或燥或湿行为愈趋复杂;3)哈尔滨区域以春燥、暑湿和冬湿为主,广州区域以长湿和凉燥为主,北京区域以暑湿和冬燥为主,西安区域以短暂的春燥和较弱的秋湿为主,乌鲁木齐区域以春燥、夏火(热而燥)和冬湿为主;4)年际变化哈尔滨区域和乌鲁木齐区域燥气流行突出,广州区域燥湿气时段大致相当,北京区域燥气时段略长,西安区域燥湿气相对较弱;5)病毒性肝炎发病率与燥湿呈明显反相位,燥气时段明显长于湿气,肝长期受邪,与我国成为世界肝病高发区相关;6)燥湿邪典型地域性,具有地方病的特点。To reveal abnormal distribution and pathological significance of drying in China, national day - observed data during 1951 -2005 such as relative humidity and mathematical methods was used to analyze using EOF,REOF andWavelet analysis methods. Research indicates that： 1 ） China dry - dampness exception existed in Harbin region, Guang- zhou region,Beijing region,Xi＇an region and Urumqi region, 5 class high related typical areas. 2）Dryness- dampness changes, by South to North and by East to West became more and more cluttered and the changing range became intensi- fied, dryness or dampness behaviour became more and more complex. 3） Harbin region had spring dryness, summer damp- ness and winter dampness mainly. Guangzhou region had long dampness and cool dryness mainly. Beijing region had summer dampness and winter dryness mainly. Xi＂an region mainly had short of spring dryness and weaker of autumn dampness. Urumqi region mainly had spring dryness, and Xia Huo （hot and dryness in summer）and winter dampness. 4） In years inter - changes, Harbin region and Urumqi region were dominated by dryness. Guangzhou region had the gen- eral!y equal period of dryness and dampness. Beijing region had a longer dryness period. Xi^n region had relative weaker dryness and dampness. 5） The viral hepatitis incidence was obvious anti - phase with dryness - dampness, dryness period obviated longer than dampness period. Liver being damaged for long time was related to high incidence of liver disease in China in the world. 6）Dry and dampness evils had typical local features and endemic diseases characteristics.
