摘    要: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

关 键 词:元素聚散  古气候变化  气候期  内蒙古盐海  子盐湖

Abstract:The results obtained in dually testing on the 35 samples collected from the borehole Ya02 in Yanhaizi saline lake in Yikezhao League, Inner Mongolia, in terms of the change in the propotion of elements such as Al, Fe, K, Na, Ca, Mg, F, Cl, Ti, Mn and Ba reveal that the association and composition of these elements are constrained seriously by the fluctuation of climate at that time, with a close relativety between the two variables. All this helps define 13 climatic stages since the formation of the saline lake, thereby proposing a model showing the shift between cold/damp and warm/arid climates from the Late Pleistocene times down to the present. The Late Pleistoncene times was dominated by a cold, damp climate except for a few epsoides of relatively warm, arid, but slightly damp, variations. Afterwards, climate continued to fluctuate from warm and damp for the Ealy Holocene times through warm, arid, and epicodically cold and damp for the Middle Holocene times to cold and damp for the Late Holocene times. The climatic situation, cold and damp, of the latest geohistorical period has been confirmed by the overall increase in the contents of the tested elements.
Keywords:centralization and decentralization of elements  paleoclimatic fluctuation  climatic stage  Yanhaizi saline lake in Inner Mongolia
