摘　　要：第四纪晚期柴达木盆地与珠江三角洲的气候都呈现出冷暖旋回的波动特征,引起相应的环境变迁.但两地各期的波动起讫时间年代有较大差异,柴达木盆地的降温时间明显早于珠江三角洲地区,降温幅度明显.两地都有全新世气候适宜期,但纬向和经向的差异都很大.两地的气候波动变化、进退迁徒、突发事件的对比在一定程度上反映或代表中国大陆上气候演变的普遍特征.The climates both in the Qaidam Basin and the Pearl River Delta presented cycle characteristic of cold and warm fluctuation since the Late Quaternary. The climate change caused relevant environmental evolution. But the ages of each stage at the two regions were completely different. The temperature dropping times of Qaidam Basin were obviously earlier than that in the Pearl River Delta region, the dropping scales were obvious. The Holocene Megathermalre existed in the two regions, but the latitudinal and longitudinal differences were obvious. It reflected and represented the widespread characteristics of the environmental evolution in the China continent, such as the climate fluctuations, advance and retreat of the physical geographic zones and the outburst events.
