Abstract：Theories of sedimentology，stratigraphy，plate tectonics and so on，were used to study the sedimentary characteristics of the Late Paleozoic in Linqing Depression, Bohai Bay Basin.Single factor analysis and multifactor comprehensive mapping method was used to reconstruct quantitative lithofacies palaeogeography and the evolution characteristics was concluded.The results are as follows: There are five sedimentary types in the research area，which are barrier-lagoon，tidal flat，carbonate platform，fluvial-controlled shallow-water delta and meandering fluvial-lacustrine deposits. Tidal-flat and carbonate platform deposits are the primary deposits in Benxi period. Carbonate platform,barrier-lagoon and tidal-flat deposits are the primary deposits in Taiyuan period.Fluvial-controlled shallow-water deltaic deposits are the primary deposit in Shanxi period，Meandering river and flood plains deposits are the primary deposits in Xiashihezi period，Meandering fluvial and lacustrine deposits are the primary deposits in Shangshihezi period.The basin evolution can be divided into three stages: The first stage is Benxi and Taiyuan periods of the Late Carboniferous-Early Permian and its mainly feature is the epicontinental sea sedimentary succession;the second stage is Shanxi period of the Permian and the transitional environment is the main feature;the third stage is Shihezi period of the Permian and terrestrial strata is the main sediments.
