中文摘要	根据库车河剖面三叠系和侏罗系干酪根显微组分的分布特点，将干酪根显微组分划分为5种组合和12种亚组合，结合沉积特征等资料推测每一种亚组合所对应的沉积环境。根据孢粉化石母体植物的生态习性推测三叠系和侏罗系沉积时期古气候的变化规律是：由半干旱(俄霍布拉克组)一半潮湿(克拉玛依组下段)一潮湿(克拉玛依组上段一克孜勒努尔组下段)一半干旱、半潮湿(克孜勒努尔组上段一恰克马克组)一半干旱(齐古组、喀拉扎组)；由热带、亚热带型气候(俄霍布拉克组一塔里奇克组)一亚热带一暖温带型气候(阿合组一克孜勒努尔组)一亚热带型气候(恰克马克组一喀拉扎组)。根据干酪根显微组分、沉积特征等资料推测俄霍布拉克组、克拉玛依组上部标志层段、黄山街组二段一四段中部和下部、阳霞组上部标志层段和恰克马克组为该区三叠系到侏罗纪五个主要的湖泊(滨浅湖、半深湖一深湖)发育期；齐古组为洪泛湖泊发育期；塔里奇克组、阳霞组下段和克孜勒努尔组为三个主要的沼泽 (以河沼为主，如岸后沼泽、分流间沼泽等)发育期。
英文摘要	In the Kuqa River area, the kerogen maceral of the Triassic-Jurassic may be di?vided into 5 assemblages and 12 subassemblages based on its distribution characteristics. The evolution of paleoclimate during sedimentation of the Triassic-Jurassic inferred on the basis of ecology of sporopollen s plants is semi-arid (Ehuobulake Formation ) semi-humid (Lower Karamay Formation ) humid (Upper Karamay Formation-Kezilenur Formation ) -semi-arid and semi-humid ( Upper Kezilenur Formation-Lower Qigu Formation ) semi-arid ( Middle-Upper Qigu Formation-Kalaza Formation ); and the evolution of paleoclimate type is tropic-subtopic (Ehuobulak Formation-Taliqike Formation ) subtropic-warm temperate (Ahe For-mation-Kezilenur Formation ) sub tropic (Qiakemake Formation-Kalaza Formation ) . On the basis of kerogen maceral, sedimentary characteristics and other data, it is inferred that lacus?trine deposition is most developed in the Ehuobulake Formation, Upper Marker Member of the Karamay Formation, middle-lower part of Members 2 to 4 of the Huangshanjie Formation, Upper Marker Member of the Yangxia Formation and Qiakemake Formation of the Triassic-Jurassic in this area. The flood lake deposition is developed in Qigu Formation, and the swamp deposition (mainly fluvial swamp )is developed in the Taliqike Formation, lower Yangxia For?mation and Kezilenur Formation.
