笔者通过对古地理、古气候、古生态的研究,认为相同的古气候条件使得西北地区诸盆地具有相似的古生物群落和沉积特征,侏罗系时我国西北诸盆地是由古天山、古祁连等山系分隔的相互独立的盆地,并不存在“侏罗纪泛湖”。
Through the study of palaeogeography, paleoclimate and paleo-ecology, the author thinks that the same paleoclimatic conditions make the basins in northwestern China have similar paleontological communities and sedimentary features. In the Jurassic, all the basins in northwestern China were formed by the ancient Tianshan and the ancient Qilian There are no “Jurassic pan-lake” basins that separate from each other.
