| Research on Climatic and Environmental Changes in the Ningjin Lake since the Holocene Climatic Optimum |
| Climatic fluctuation and process of lake changes were revealed through high resolution analysis on environmental indices based on sediments of Ningjin Lake. In the period of climatic optimum( p CO ), climate was warm and stable,precipitation was high, and there were a lot of herbs and trees aroud lakes. But there was a short period of low temperature from 6000 aBP to 5500 aBP. In late of p CO , climate was unstable and obviously fluctuated. In Late Holocene, the temperature fluctuated regularly, and this was very coincident with the record in historical data. |
