笔者通过国内第四纪盐湖沉积的长期实地考察以及盐湖长期科学观察站的实验研究，并结合国内外大量盐湖沉积实验研究资料，以比较盐湖沉积学的理论和方法，将盐湖沉积划分为冷相、暖相和广温相，揭示现代全球盐湖水化学类型分带与气候分区的一致性；指出我国第四纪存在6次干旱（成盐）扩张期；识别出中国第四纪干旱中心19个明显的强冷偏湿-冷干事件及8个明显的暖偏湿-暖干事件，并推算其古气温变化范围。
Based on the long-term field investigation of the Quaternary Salt Lake sediments in China and the experimental study of the Longyan Scientific Observation Station in Salt Lake, combined with a large amount of experimental data of salt lake sediments at home and abroad, the author compares the salt lake sediments with the cold phase , Warm phase and broad temperature phase, revealing the consistency of the modern global salt lake water chemistry type zonation and climatic zonation; pointing out that there are six drought (salt-forming) expansions in Quaternary of China; identifying 19 of China’s Quaternary Arid Center Obvious strong cold partial wet - cold dry event and eight obvious warm wet - warm dry event, and calculate the range of paleocurrent temperature changes.
