经过几代中国第四纪环境研究者的努力,已经认识到,中国黄土堆积是过去250万年以来连续的风成沉积物,黄土堆积序列中的粒度、磁化率、碳同位素、生物化石等可以作为古气候与古环境变化的良好替代性指标,中国黄土堆积中包含着最近250万年以来东亚季风气候与黄土高原植被变化过程等信息。中国黄土已经成为认识第四纪地球气候与环境变化的三个重要信息载体之一。对黄土记录的深入研究,将对理解地球系统变化的规律与机制、为黄土高原以及中国西北地区的生态环境建设提供科学依据。
After several generations of environmental researchers in Quaternary China, it has been realized that the loess accumulation in China is a continuous aeolian sediment over the past 2.5 million years. The grain size, magnetic susceptibility, carbon isotopes, and biological fossils in the loess accumulation sequence can be As a good alternative indicator of palaeoclimate and paleoenvironmental changes, the loess accumulation in China contains the information of East Asian monsoon climate and the change of vegetation on the Loess Plateau since the last 2.5 million years. Chinese loess has become one of the three important information carriers for understanding the climate and environmental changes of the Quaternary. In-depth study of loess records will provide a scientific basis for understanding the laws and mechanisms of changes in the Earth system and for the ecological environment in the Loess Plateau and Northwest China.
