A positive correlation was found between the solar activity and NO3- concentration in recent 1500 years. A long-standing issue of the nature of the solar activity during the Maunder Minimum was solved. An about 36a cycle was found in the solar activity. Low solar activity and weak geomagnetic field were responsible for the 36Cl peak at about 37ka BP. Climate change recorded in this ice core lagged insolation about 4ka during the last glacial maximum, about 1ka during the last deglaciation, and nearly 0ka during the Holocene.δ18O record also suggests that the variation in temperature on the Tibetan Plateau had some similar features to that in both Northern and Southern Hemispheres during the last deglaciation to some extent, which indicate that the tropics maybe play an important role on global climate change.

揭示出近1500a来古里雅冰芯中NO3-浓度变化可以反映太阳活动的强弱变化；回答了长期争议的并直接关系到太阳发电机理论是否正确的Maunder极小期太阳活动特征问题；发现太阳活动可能存在36a左右的周期；证实了37kaBP左右古里雅冰芯记录中宇宙成因同位素36Cl含量峰值的存在，指出这一时期的宇宙成因同位素峰值事件具有全球性，弱的太阳活动和弱的地磁场是这一事件发生的原因所在；揭示出古里雅冰芯记录到的"8.2ka BP事件"，认为这一全球性事件发生的主要原因与弱的热盐环流和弱的太阳活动有关；发现古里雅冰芯记录的末次冰盛期和末次冰消期气候变化均在一定程度上滞后于太阳辐射变化，而全新世气候变化大致与太阳辐射变化同步；发现末次冰消期高原地区气候变化不仅具有北半球气候变化的某些特征，同时还具有南半球气候变化的某些特征，这说明热带地区可能对全球气候存在重要的影响。
