| 摘 要： | 通过对西北地区侏罗纪孢粉学特征的研究，并结合岩石的物理属性，认为中侏罗世晚期到晚侏罗世末存在一次最为明显的升温事件，其主要原因是由于侏罗纪全球性气温升高所导致．这次升温事件影响和改变了当时的成煤气候，并导致了早侏罗世－中侏罗世晚期聚煤作用的终止和消亡．

| Abstract: | ccording to researches on Jurassic Sporopollen features and physical characters ofrocks in northwest area, it has been considered that the most obvious temperature-riseevent, happened in the late stage of Middle Jurassic to the end of Late Jurassic time, resultsmainly from the global temperature-rise of the Jurassic. This event influenced and transformed the coal forming climate at that times; and led to the Early Jurassic-late MiddleJurassic coal-forming process to end off and die out. |
