摘　　要：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”。Based on the studies on palaeogeography, palaeoclimate and palaeoecology, the writer think that the same palaeoclimate resulted in the similarities of palaeobiocoenosis and sedimentology developed in each basin in Northwest China. In Jurassic, the basins in Northwest China were separated by palaeo-Tianshan, palaeo-Qilianshan and other mountains, so there was no Jurassic Pan-lake developed.
