中华人民共和国成立以来,特别是无产阶级文化大革命以来,广泛地开展了黄土和黄土地质环境的研究。这里主要介绍黄土的分布和地层,黄土与其他第四纪沉积物的关系,以及黄土的物质成分和结构的研究成果。从黄土沉积时期地质环境的特点和黄土成因等说明中国第四纪时期有干湿气候的交替变換和多次的气候波动。这些研究成果对于利用与改造黄土和黄土
Since the founding of the People’s Republic of China, especially since the Great Proletarian Cultural Revolution, the study on the geological environment of loess and loess has been carried out extensively. Here mainly introduces the distribution of loess and stratigraphy, the relationship between loess and other Quaternary sediments, as well as the research results of the material composition and structure of loess. From the characteristics of geological environment during the loess depositional period and the genesis of loess, it shows that the Quaternary period of China changed alternately with the wet and dry climate and the climate fluctuated many times. These research results for the utilization and transformation of loess and loess
