The Xiaoqinghe River drainage is a wide area which extends from Jinan City in the west,to the Bohai Bay in the east,from the foot of TaiLuYi Mountains in the south and to the Yellow River in the northLakes were distributed widely in Xiaoqinghe River drainage during the prehistoric and historical periods which can be shown by the strata records and ancient documentsThese lakes were formed in the Early Holocene and reached peak in the Middle HoloceneSince the Late Holocene,the lakes gradually shrank until finally disappeared such as the Queshan Lake,the Hushan Lake and the Qingshui Lake,etcThe paper analyzes the reasons why these lakes disappeared in Xiaoqinghe River drainage by historical documents,analysis of stratigraphic profiles and research of place namesIt proposes that under the drying climate background,the lakes disappeared mainly because that:firstly clay and sand silted up by the Yellow River flooding;secondly human activities generated great effectsResearches on the formation and disappearence of the lakes in the study area are important for reconstructing the ancient environments and discussing their evolution process
