| 摘 要： | 宁晋泊沉积物的环境指标高分辨率分析，揭示了作新世温暖期以来气候变化规律和湖泊演化过程。全新世温暖期早期，气候温暖，降水丰沛，环境稳定，湖泊水草茂美；其中在５５００－６０００ａＢＰ有一个短暂的降温过程；温暖期晚期，气候波动明显。全新世晚期，气候呈规律性波动，与华北地区文史资料一致，具有良好的可比性。

| Abstract: | 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. |
