秦岭太白山佛爷池最近１０００年的孢粉记录及据此所重建古气候参数的时间序列，揭示了历史时期小冰期和中世纪温暖期的气候特征。小冰期的起止时间为１４２０—１９２０ａＡＤ。其１月与７月平均温度反映本区夏季风与冬季风的变化有很大的不一致性。小冰期开始时，冬季风突然增强，夏季风显示不稳定波动，并相对变弱，而降水一度增多。小冰期的结束是以冬季风逐渐减弱为先导，而夏季风呈突然增强势态，降水偏少。在中世纪温暖期中，１２００—１３４０ａＡＤ发生快速气候波动，出现暖夏、冷冬等特征气候，成为历史上少见的灾害性气候时段。
The spore-pollen records of the Taibai Mountain Fudayu Pool in the Qinling Mountains and the time series of paleoclimate parameters reconstructed from this map reveal the climatic characteristics of the pale-ice age and the warm period of the Middle Ages. The beginning and ending time of the Little Ice Age is 1420-1920aAD. The January and July mean temperatures reflect great inconsistencies in the change of summer monsoon and summer monsoon in the region. At the beginning of the Little Ice Age, the winter monsoon suddenly increased, the summer monsoon showed unstable fluctuations and relatively weakened, and the precipitation increased once. The end of the small ice age is the gradual weakening of the winter monsoon as the guide, while the summer monsoon showed a sudden increase trend, rainfall less than normal. During the warm period of the Middle Ages, the rapid climate fluctuation of 1200-1340aAD occurred, and the characteristic climate of warm summer and cold winter appeared, becoming the rare catastrophic climate period in history.
