本文初步研究了甘孜黄土地层，实测了甘孜县城西南郊新市区和满地两剖面，它们分别厚２３．７ｍ和２６．０ｍ。根据岩性、磁性地层特征、磁化率、ＣａＣＯ３质量分数测定和热释光测年结果，甘孜黄土可划分为冰后期Ｓ０复合古土壤，末次冰期Ｌ１复合黄土和末次间冰期Ｓ１复合古土壤等３个地层单位。布莱克反向极性亚时记录于底部Ｓ１ＬＬ１黄土中。甘孜黄土沉积始于晚更新世早期，大约为１２０ｋａＢＰ。甘孜黄土的磁化率变化反映了最近１２０ｋａ来的高原季风演化和气候环境变迁，６个磁化率高值段指示了６个夏季风环流增强的时段，６个磁化率低值段则代表了６次夏季风减弱时期。甘孜黄土可与黄土高原同期黄土进行对比，但又存在明显差异。
In this paper, a preliminary study of the Ganzi loess stratum, the new urban area and the Manchurian section of the southwestern suburbs of Ganzi County were measured, which were 23.7m and 26.0m thick respectively. Based on lithology, magnetostratigraphy, magnetic susceptibility, CaCO 3 mass fraction and thermoluminescence dating, the Ganzi loess can be divided into S0 composite paleosol in late ice stage, L1 composite loess in the last glacial stage and S1 composite paleosol in the last interglacial stage.3 Stratum. Black reverse polarity sub-recorded in the bottom S1LL1 loess. The Ganzi loess sediments began in the late Pleistocene, about 120kaBP. The change of magnetic susceptibility of Ganzi loess reflects the plateau monsoon evolution and climate change in the recent 120 ka. Six high magnetic susceptibility sections indicate six periods of enhanced summer monsoon circulation and six low magnetic susceptibility sections represent six times Summer monsoon weakened period. The Ganzi loess can be compared with the loess in the same period of the Loess Plateau, but there are obvious differences.
