Because the rock characteristics, granularity features and spore-pollen assemblage features of sedimentary material in lake facies can be used to show the environment, Judian Lake sedimentary area which lies in the south coastal plain of Laizhou Bay is studied on sedimentology. The vertical sedimentary sequence of this sedimentary area is divided combining with the granularity features and rock characteristics of sediments. By comparing with the strata of "Holocene Series of the coastal plain of Laizhou Bay" and combining 14C age measurement, the strata position, features of the lagoon-shallow sea-beach sedimentary facies and the sedimentary environment of each stratum are confirmed. By spore-pollen analysis of 10 samples and the features of spore-pollen assemblage and climatic environment, the features of environmental evolvement in the south coastal plain of Laizhou Bay since the Middle Holocene were summarized.
