| 摘 要： | 新疆伊犁河谷海拔高度不同的两个晚更新世黄土剖面磁化率特征存在显著差异:位于海拔1400 m处的库尔德能布拉黄土剖面,其磁化率特征与黄土高原黄土相同,而海拔850 m处塔勒德黄土剖面的磁化率特征则与黄土高原相反.对两个剖面黄土-古土壤磁化率特征等分析研究认为,造成两个剖面S1古土壤磁化率差异的主要原因是末次间冰期土壤发育时期前者降水量大于后者.

| Abstract: | The characteristics of magnetic susceptibility from two later pleistocene loess sections at different altitudes are significantly different and the characteristics of loess-paleosol magnetic susceptibility in the loess section at an altitude of 1400 m is identical with those of the Loess Plateau, but it is not the case in the loess section at an altitude of 850 m. The difference in precipitation between the two sections is responsible for their difference in magnetic susceptibility. |
