摘要
According to field investigation, soil thickness determination, indoor grain size anatysis, CaCO3 content analysis and microstructure identification, it is known know changes in climate and eolian deposits since about 8 500 years ago in Xi’an. The data show that Holocene climate, compared with that in the first stage of last interglacial, had more frequent changes and variations. Compared with the last glacial which was 75 000~10 000 years ago, eolian deposits and sand storm activity since 3 100 a BP have been much stronger. The reason for this is the strong dry climate.
