| Zusammenfassung |
| The quantitative reconstruction of the palaeoclimate is a
prerequisite for understanding climate processes at time scales of centuries
and millennia. Here, the coexistence approach (CA) was applied to
reconstruct climatic factors quantitatively based on the fossil charcoal
records between 5200 and 4300 cal yr BP in the Tianshui Basin, NW China. The
CA analysis showed that the climate of the Tianshui Basin belonged to the
northern subtropical zone between 5200 and 4300 cal yr BP. The mean annual
temperature (MAT) was approximately 13.2 °C, and the mean annual
precipitation (MAP) was approximately 778 mm between 5200 and 4900 cal yr BP.
The MAT was approximately 13.2 °C, and the MAP was approximately
688 mm between 4800 and 4300 cal yr BP. The MAT was approximately
2.2 °C higher than today, and the MAP was approximately 280 mm higher
than today from 5200 to 4900 cal yr BP. The MAT was also approximately
2.2 °C higher than today from 4800 to 4300 cal yr BP, while the MAP
was approximately 196 mm higher than today. No abrupt cold event occurred
between 5200 and 4300 cal yr BP; however, a drought tendency appeared after
around 4800 cal yr BP. |
