According to the analysis on historical documents and research on borehole sections in Juye,Liangshan and Daimiao and the investigation of lake basal sediments in Dongping Lake,the sedimentary records of Dayeze Lake,Liangshanpo Lake,Anshan Lake and Dongping Lake are determined and the authors propose that the Dongping Lake was evoluted from Dayeze Lake,Liangshanpo Lake and Anshan LakeBy analyzing the relationship between the evolution of Dongping Lake and the crevases and shifting ofthe Yellow River,it is suggested that the evolution process of Dongping Lake inhistorical periods was closely related with the Yellow RiverDuring the crevasesand shifting of the Yellow River,water poured into and lake expanded,river shifted and lake shrankThe Yellow River poured into it during itsfirst shifting stage and flowed across Dayeze LakeThe Yellow River poured intoit twice during the second shifting stage,among which once shifted and flowed across Dayeze Lake,and the water transgressed northwards and formed the LiangshanpoLakeDuring the third shifting stage,the Yellow River crevassed and poured intoit three times,shifted and flowed across the Liangshanpo Lake twice which led to the further expansion of the lake and finally formed socalled the “Babaili Liangshanpo Lake”.After that the Yellow River poured intoit several times,the sources shortened and the lake shrankThe Yellow River did not flow through theLiangshanpo Lake during its fourth shifting stage,with the lake shrank furtherThe Yellow River poured into the Liangshanpo Lake twice during its fifth shifting stage and the lake expandedThen the source of the Yellow River was cut off and the lake was separated into northern five lakes including Anshan Lake,while the Liangshanpo Lake became land because of the filling of sediments for a long whileThe source of the Yellow River was cut off during its sixth shifting stage,with the northern five lakes migrating to the north and gradually shrinking and disappearingOnlythe Anshan Lake experienced the pouring of the Yellow River once and was filled to form the Dongping LakeThe lake was dried up when the source of the Yellow River was cut off and the water of the Yellow River once flooded back into it during the flooding periods
