图6 两个剖面记录的全新世气候环境（a~d为KS16剖面记录，e为LJW10剖面记录）与区域及北半球记录对比（f为TLD剖面蜗牛化石总数［30］，g为新疆区域湿度集成曲线［38］，h为基于阿尔泰山泥炭α-纤维素δ13C重建的温度曲线［39］，i为北半球高纬度冰盖面积变化［44］，j为北半球高纬度太阳辐射［45］）

Fig.6 Regional climatic environment during the Holocene recorded by two loess sections （a~d are records from KS16 section， e is from LJW10 section） and their comparison with regional and northern hemisphere records （f is the total count fossils from TLD section［30］， g is the synthesis of moisture changes in Xinjiang region［38］， h is the reconstructed temperature variation from the peat α-cellulose δ13C of Altai Mountains［39］， i is the variation of northern hemisphere high-latitude ice sheets in million km2［44］， j is the northern hemisphere summer insolation［45］）
