Average Annual Temperature Changes in the Holocene in China
Authors:BI Fuzhi and YUAN Youshen Peking University  Cheng Ze Yuan  Beijing
Abstract:Abstract: In 1876 Blytt proposed a post-glacial climatic classification, maintaining that the then temperature fluctuated 1–2°C higher or lower than that today. Lamb (1969) held that in Europe “the axis of the subtropical high pressure belt was generally displaced north by about 10° latitudes” during the Hypsithermal and that the temperature was three to six times higher than that in the postglacial period. In China, there appear relict beachrocks (living fossils) in tropical tidal zones from the Bohai Bay (40° N) to coastal areas in South China. Many relict tropical marine fossils were discovered, such as Ostrea gigas in Tianjin (which is larger than that found today in Hainan), Placuna placenta in Zhejiang and Spondylus sp. in Fujian. In Hebei, Henan and Zhejiang provinces and Guilin of Guangxi, such tropical fossil animals as Elephas maximus and Rhinoceros sp, were discovered, and in Hebei and Jiangsu provinces such fresh water fossils as Unio douglasiae were found. Their living species are still seen in South China today. Skeletons of Banpo Man discovered at Xi‘ an are more similar to those of the “South Chinese race, and human skulls found at Guilin possess characteristics of the” Australoid—Negroid race“. Abstract: All phenological evidence shows that the average annual temperature of every warm phase in the Holocene in China was 10–15°C higher than the present temperature in North China and 10°C, 7°C and 2°C higher than the present values in Zhejiang, Fujian and Hainan, respectively.
