| 摘 要： | 新疆早二叠世古气候可以划分为两个不同的气候区，即准噶尔温带气候区和塔里木热带—亚热带气候区。准噶尔早二叠世的气候特点是间歇性地出现炎热气候，这些气候变化大致可以划出两个气候旋回。塔里木早二叠世由潮湿环境转变为比较干旱的环境，晚期。红层普遍发育。影响准噶尔早二叠世气候的主要因素为全球气候变暖和火山作用。影响塔里木早二叠世气候的主要因素包括处于偏低纬度的地理位置、古特提斯洋暖流、周缘火山活动，海退使整个塔里木运动远离海洋。

| Abstract: | Two paleoclimate regions are are included in Xinjiang at lower Permian, that is, the Junggar temperate zone and the Tarim tropics-subtropics zone. The paleoclimate of lower Permian is characterized by intermittence of burning hot weather in Junggar. Two cycles of climatic change can be divided. At Permian a change from moist to arid occured in Tarim, and later red beds were generally developed. The main factors of causing the climatic change of Junggar at Early Permian are worldwide warding and volcanism, and for Tarim they are lower lattitudes, warm current of Tethys, volcanism of the surroundings and regression. |
