十九世纪七十年代以来,中外学者在青海湖区进行过多次地质地理调查,但对本区第四纪地层迄今研究甚少,也未从其中发现过生物遗体。本文试图根据孢粉组合对本区第四纪地层划分、古气候变化及青海湖形成时间等问题作一初步探讨。 Since the 1970s, Chinese and foreign scholars conducted many geological and geological surveys in the Qinghai Lake area, but few studies have been done on the Quaternary strata in this area so far, and no biological remains have been found. This paper tries to make a tentative discussion on the division of Quaternary stratigraphy, paleoclimatic change and the formation time of Qinghai Lake according to the sporopollen assemblage.
