通过对内蒙古盐湖沉积物同位素、元素地球化学、古地磁、古生物、沉积岩石学等大量第一手资料的研究证实，中国内蒙古地区存在ＹｏｕｎｇｅｒＤｒｙａｓ气候期。所获之研究成果以其Ｙ．Ｄ．的高分辨率、冷湿型、持续时间、温度范围等属性特征而获得国内外的确认，这对更新世和全新世的划分及推动第四纪环境地质研究均具有重要意义 Based on a large amount of first-hand data of isotopes, elemental geochemistry, paleomagnetism, paleontology and sedimentary petrology of salt lake sediments in Inner Mongolia, it is confirmed that there is a YoungerDryas climate in Inner Mongolia, China. The research results obtained by its Y. D. High-resolution, cold and wet type, duration, temperature range and other properties of the domestic and international recognition, which is important for the division of the Pleistocene and Holocene and to promote Quaternary environmental and geological research
