摘要
对青海共和盆地东部上更新统一全新统地层中第一过渡元素分布的研究表明,该地自晚更新世以来交替经历了四次土壤发育的相对暖湿期和四次风沙堆积的干冷期。
The study on distribution of the first transitional elements from the late Pleistocene - Holocene strata in Gonghe Basin, Qinghai province, shows that since late Pleistocene there occurred four times of relatively warm - wet climate and four times of cold - dry climate, they can be identified by palaeosol and palaeo-aeolian sand respectively. Such climatic conditions appeared alternately.
