| 摘 要： | 通过对新疆吐哈盆地侏罗系孢粉植物群、特殊岩性、泥质岩中的元素和粘土矿物分布规律的研究 ,探讨了古植被、古气候及古环境的纵向演化特点 ,认为研究区内侏罗纪古气候特点是早侏罗世至中侏罗世早期为温暖潮湿的亚热带 ,局部有干旱趋势 ;中侏罗世中晚期为半潮湿、半干旱的温带—亚热带气候 ;从中侏罗世末期开始转为炎热干旱的亚热带气候。

| Abstract: | In this paper, the vertical evolution of palaeovegetation, palaeoclimate and palaeoenvironment in the Tuha basin is probed from the Jurassic palynoflora, special lithology, and the distributions of elements and clay minerals in the argillaceous rocks in the Tuha basin. It is concluded that this region was a warm and humid subtropical climate locally with drought trend from Early Jurassic to Early Middle Jurassic stage, semiarid semihumid temperate to subtropical climate from Middle to Late Middle Jurassic stage, and became a hot and arid subtropical climate after the end of Middle Jurassic stage. |
