Abstract: Bused on analysis of the habitat type of the Early Triassic twenty communities of,Jianghan Basinand the crosswextendance of communities of every age, the Early Triassic evolution of sea level andpaleogeography are discussed in this paper, furthermore the Early Triassic ecosgstem is divided into sixevolution wry stages. Based on the study of the Early Triassic。ostratigraphy of,Jianghan Basin, the au-thorn have firstly established the Early Triassic ecostratigraphic system of,Jianghan Basin, which con-twins twenty community zones, ten community formations and three community groups. Their distribu-ti on s, compositions, ecologic environment evolutions aswell as top and bottom boundary lines are ex-pounded in this paper as well.
