中国区域运气学说适宜性研究(Ⅱ)--寒热气候

On Suitability of TCM Yunqi Theory(Ⅱ):Cold-Hot Climate Change

为了评估运气学说的科学价值,本文利用全国55年逐日气温实测资料,主要采用自然正交分解函数旋转自然正交分解函数EOF和旋转自然正交分解函烽REOF等数理方法,对我国寒热气候进行运气学说适宜性予以评价。研究表明:①运气学说推演结论能够概括我国热寒变化的最主要演变特征;②5年是我国寒热气候演变振荡主周期,与“五运”更迭5年周期一致,是运气学说具有科学价值的根本;③2~3年和准8年次振荡周期,较“五运”更迭周期(5年)存在着“过或不及”;④我国寒热气候变化由东南向西北愈趋杂乱、变化幅度加剧,或寒或热行为愈趋复杂,寒热异常存在3类高相关典型区,西部区寒热波动较大,东部区波动居中,中部区较小;⑤运气学说“六气从化、主客加临、司天在泉”等订正方法,兼顾了我国寒热气候准周期振荡和地域差异特点;⑥运气学说在我国仍具有广泛适宜性,在周期特点、阶段性和地域性等方面尤为突出。

This study attempted to assess the scientific value of TCM Yunqi theory by applying EOF(empirical orthogonal function)and REOF(rotate empirical orthogonal function)and other mathematical methods to the national daily relative humidity data during 1951-2005yr.Firstly,the study results suggested that Yunqi theory could exhibit the most characteristics of national temperature distribution about cold-hot weather periodic evolution in China.Secondly,the quasi-5a periodic oscillation was the basic period of"five evolutive phases" and the most important periodic characteristics which constituted the most scientific value of the theoiy.Thirdly,the cold-hot climate evolution period of quasi-2-3a and 8a was over or inferior to the basic periods of 5a.Fourthly,there were three high significant correlation regions in cold-hot weather changes which were more complex and chaotic in tempo ration fluctuation from southeast to northwest.Fifthly,despite of quasi-periodic oscilkition and regional differences,the result could be greatly improved by some adjusting methods,such as "liuqi conghua,zhuke jialin,sitian zaiquan".Lastly,the theory of Yunqi could still be widely applied in various parts of China at present,and has some unique advantages in the description and prediction of period characteristic,evolution stage and the regional difference.
