Abstract：Based on the quantitative and qualitative data of outcrops and well sections，according to the single factor analysis and multifactor comprehensive mapping method，the lithofacies palaeogeography of the Late Permian early Wuchiapingian in Wenshan，southeastern Yunnan Province，was studied and mapped.The research results are as following:（1）The Kangdian old land and the Pingma-North Vietnam old land was located to the western and southeastern of Wenshan during the Late Permian Wuchiapingian Age，and the sedimentary facies was distributed successively from the southwest to the northeast，including swamp-supratidal，intertidal，subtidal and restricted shallow sea facies;（2）The Kangdian old land and the Pingma-North Vietnam old land were the common material sources provider;（3）The sediments of Tianshengqiao area were deposited with large thickness，which constituted the depocenter;（4）The basin topographic center was located in the northeast of the study area；（5）Bauxites were mainly deposited in subtidal and restricted shallow sea area，and these sedimentary facies area should be the main perspective area for ore exploration.
