依据对塔里木盆地北部库车河剖面及沙１１井和沙３２井三叠纪地层和孢粉学的研究，将本区三叠纪孢粉划分为８个孢粉组合。其中，早三叠世２个组合，中三叠世３个组合，晚三叠世３个组合。三叠纪地层除产有丰富的孢子花粉外，在不同层位还有不同丰度和分异度的疑源类、轮藻、介形虫及植物化石等。依据不同层位中各类生物的不同丰度，建立了１１个生物埋藏群落，它们反映了不同的生态和埋藏环境。按照这些生物埋藏群落在剖面纵向上的演变，将塔里木盆地北部三叠纪地层划分为９个三级地层层序，恢复了三叠纪塔里木盆地北部古湖盆湖平面的升降历史
Based on the Triassic strata and palynology of the Kuche River profile in the northern part of the Tarim Basin and wells Sha 11 and Sha 32, the Triassic sporopollen in this area is divided into eight sporopollen assemblages. Among them, there are two assemblages in the Early Triassic, three in the Middle Triassic and three in the Late Triassic. Triassic strata in addition to producing a rich spore pollen, in different layers there are different abundance and differentiation of the source class, Chara, ichthyosis and plant fossils. According to the different abundance of all kinds of organisms in different layers, 11 biological burial communities have been set up, which reflect different ecological and burial environments. According to the longitudinal evolution of these burial communities, the Triassic strata in the northern part of the Tarim Basin are divided into nine tertiary stratigraphic sequences, which restore the level of the rise and fall of the ancient lake basins in northern Triassic Tarim Basin
