摘要: 大安县和扶余县位于东经123°15’~125°30’,北纬44°50’~45°40’。本区属温带半干旱、半湿润气候区,植被区划属于内蒙、东北草原区的一部分(见图1)。本区位于松辽盆地次一级构造——月亮泡断陷盆地内。

Abstract: Daan and Fugu Counties are located in Yulianpao fault basin, a substru-Cture of Sonliao basin. Sediment of lacustrine and other genetic series were deposited with different spaces and times since Tertiary. Quarternary lithology is quite Complete with thickness of 60~80m,which is perfect area for studying the palaeogeography of pleistocene. For this paper, authors have described the spore-pollen composition and palaeovegetation zoning along 0~98m, 0~82m of well loggings, in Shell of Daan county and Zong shitun of Fuyu county respectively. Based on climatic-stratigraphy as well as the lithology and palaeomagnetic data, a new suggection of the lower boundary of pleistocene in developed herein.
