通过对内蒙古伊克昭盟Ｙａ０２孔３５件样品Ａｌ、Ｆｅ、Ｋ、Ｎａ、Ｃａ、Ｍｇ、Ｆ、Ｃｌ以及Ｔｉ、Ｍｎ、Ｂａ等２２项元素测试结果的研究表明，元素组合与含量变化过程严格受气候因素的控制，并反应敏感。据此将该湖自下而上划分了１３个气候期，揭示了自成湖（２３ｋａＢ．Ｐ．）以来冷暖与干湿的气候环境变化模式：晚更新世主要以冷湿气候为主，并伴有多次相对温干偏湿的气候波动；早全新世为暖湿气候；中全新世以温暖干气候为主，伴有冷湿气候；晚全新世以来，所测各元素含量趋于增高趋势，反映了气候由温暖干向冷凉湿方向渐变
The results of testing 22 elements including Al, Fe, K, Na, Ca, Mg, F, Cl, Ti, Mn and Ba in 35 samples of Ya02 hole in Yikezhao League, Inner Mongolia show that the elemental composition and content change are strictly regulated Climate factors are controlled and responsive. Accordingly, the lake was divided into 13 climatic periods from bottom to top, revealing the climate change pattern of warm, cold, wet and dry since the lake was formed (23kaB.P.): The late Pleistocene was mainly dominated by cold and humid climate Accompanied by a number of relatively warm and humid climate fluctuations; Early Holocene warm and humid climate; Mid-Holocene warm dry climate, accompanied by cold and wet climate; since the late Holocene, the measured element content tends to increase The trend reflects the gradual change of the climate from warm to cold and wet
