全新世以来塔克拉玛干北部（以下简称塔干北）主要沉积物组成为亚粘质土、细砂夹杂着粉砂。分析该区域沉积物的分层结构和粒度组成、化学元素、孢粉、碳酸钙、矿物表明：区域气候以干燥为主，并存在着高温与冷凉的温度波动，且气候的这种变化与全球气候的变化紧密相关。塔干北气候变化受全球径向环流影响较大，纬向环流影响较小。 Since the Holocene, the main sediments in the northern part of Taklamakan (hereinafter referred to as “Tadan North”) are composed of sub-clay soil with fine sand mixed with silt. The stratigraphic structure, grain size, chemical elements, sporopollen, calcium carbonate and mineral of the sediments in this area show that the regional climate is mainly dry, and there is temperature fluctuation and cold temperature fluctuation. And this change of climate The global climate change is closely related. The climate change in the north of Tarim Basin is greatly influenced by the global radial circulation and less affected by the zonal circulation.
