| 摘 要： | The characteristics of climatic environment in the early Holocene epoch were studied through analyzing environmental proxies from the sediments in the Ebinur Lake——a closed one in the arid region. The pollen assemblage and other geochemical indices showed that, the temperature was somewhat low in the period (8.0-11.5 cal kaBP) as a whole, but in the early period (11.5-10.6 cal kaBP) the temperature was higher, in company with more precipitation. In the conversion period from the early Holocene epoch to the middle Holocene epoch (8.9-8.0 cal kaBP) the climate fluctuated remarkably. Particularly the three layers of peat sediment revealed the strong instability of climate in the early Holocene epoch in the Ebinur region. All information on the development of peat and the experimental data of pollen and stable isotopes implied that, the climatic condition at 8.2, 8.6 and 10.5 cal kaBP was characterized by noticeable cold and humidness, and could be regarded as three cold and humid events in the early Holoc

| Abstract: | The characteristics of climatic environment in the early Holocene epoch were studied through analyzing environmental proxies
from the sediments in the Ebinur Lake-a closed one in the arid region. The pollen assemblage and other geochemical indices
showed that, the temperature was somewhat low in the period (8.0–11.5 cal kaBP) as a whole, but in the early period (11.5-10.6
cal kaBP) the temperature was higher, in company with more precipitation. In the conversion period from the early Holocene
epoch to the middle Holocene epoch (8.9-8.0 cal kaBP) the climate fluctuated remarkably. Particularly the three layers of
peat sediment revealed the strong instability of climate in the early Holocene epoch in the Ebinur region. All information
on the development of peat and the experimental data of pollen and stable isotopes implied that, the climatic condition at
8.2, 8.6 and 10.5 cal kaBP was characterized by noticeable cold and humidness, and could be regarded as three cold and humid
events in the early Holocene epoch. |
