新疆地处北半球西风带干旱区,有关其过去气候冷暖干湿组合的争论较多,而新疆北部平原湖泊多为封闭湖和尾间湖,对气候的反映灵敏度非常高．以孢粉数据为主,同时结合磁化率、烧失量、粒度、沉积相等辅助资料,对新疆北部平原四厂湖、东道海子湖和艾比湖所反映的湖面波动及环境变化进行了综合分析,揭示了晚全新世新疆北部平原以冷湿和暖干为主的温度与湿度组合模式,同时进行了影响因素的初步讨论．

Xinjiang is located in the arid zone in the westerlies of the northern hemisphere. There are many controversies about the combination of the warm and cold climate in the past climate. Most of the plains lakes in the northern part of Xinjiang are mostly closed lakes and hilly lakes with very high sensitivity to climate. Based on the data of sporopollen, combined with the ancillary data of magnetic susceptibility, loss on ignition, grain size and sedimentation, a comprehensive analysis of the lake fluctuation and environmental changes reflected by the Sichang Lake, Dongdaohai Lake and Aibi Lake in the northern part of Xinjiang was carried out. , Revealing the combined pattern of temperature and humidity dominated by cold and wet and warm dry in the northern part of the late Pleistocene in Xinjiang, at the same time a preliminary discussion of the influencing factors was made.
