As the latest abrupt climate event with temperature decrease from the transition of the last glacial period to the Holocene, the Younger Dryas event that occurred approximately between 12.9 to 11.6 ka BP at north Atlantic is very important on the study of abrupt climate change, while there are still many debates on its trigger site, trigger time, trigger mechanism, as well as whether it is a global event.

大约发生在12.9～11.6 ka BP的新仙女木事件在气候突变的研究中占有重要地位，然而对其触发时间、触发地点、触发机制以及YD事件是否是一个全球性的事件一直存在很大争议，并且该事件触发机制的研究对目前全球温度快速升高背景下未来气候变化的预测也有很大的意义。

; 3 younger Dryas Only has reflection in the hundred-year-scales climatic curve, it is not evident in the curve of long period; 4 in the hundred-year-scales climatic curve, the last glacial maximum fluctuation as frequuently and 18-28KaBP was the stage in which the frequency fluctuation was the largest.

；（3）新仙女木事件仅反映在百年尺度的气候曲线上，在较长周期的饿曲线上不明显；（4）在百年尺度的气候曲线中，末次冰盛期气候波动频繁，其中18-28KaBP 是频率波动的最大阶段，但随着周期尺度的加大，气候的波动频率逐渐趋于均匀。
