根据大量的古气候代用指标记录，早全新世10-8 ka BP甚至到新疆天山向西克桑洞石笋10-3.0 ka BP期间，黄土高原的降水量最高（An et al.，2000; Zhang等人，2009; Zhang等人，2018年）。然而，在甘肃定西鲁家沟地区首次发现了洪泛平原湖泊-风成地层韵律复合体，这是黄土高原全新世早期存在弱夏季风过渡期的重要地质证据。
ObjectivePrecipitation was the highest in the loess plateau during the Early Holocene 10–8 ka BP even to the period 10–3.0 ka BP in the Kesang cave stalagmite westward Tianshan, Xinjiang, based on large numbers of records from paleoclimatic proxies (An et al., 2000; Zhang et al., 2009; Zhang et al., 2018). However, we discovered at first time that floodplain lake-eolian stratigraphical rhythm complex kept in the Lujiagou of Dingxi, Gansu, which was important geological proof to indicate a weak summer monsoon transition period during the Early Holocene in the Chinese Loess Plateau.
