|Based 011 the sedimentary feature.spore-pollen analyses.the contents of geochemical ela ments and organic matter,together with the chronological results of the lacustrine sediment of Balikun Lake in the northern part of Xinjiang,this paper focuses on the climatic change during Late Glaciation.The climate during this period was characterized by alternation 0f several stadials and interstadials.and there still exists a disposal regime of hydro-and thermal-conditions.which is represented by cold humid and warm-dry on the time scaIe of 100 years.differentiating from the eastern monsoonaI area in China and the other areas over the world.but the process of climatic evoltion is synchroneous, What the paper has revealed is a non-linear climatic change during Late Glaciation in the northern part of Xinjiang,the most extreme arid inland area.which may be all important significance for providing some fresh insights into “The Climatic Abrupt Change Events”.
