| 摘 要： | 本文通过对岱海游乐场钻孔剖面沉积物孢粉的定性、半定量分析，并结合岩性、岩相变化，初步恢复了该地区２５００年来古植被、古气候演化过程。研究结果表明，岱海湖盆自２５００年来植被类型有典型草原—灌丛草原—森林草原—灌丛草原的演化过程，古气候有较暖湿—较暖干—较冷干—较冷湿—较冷干的变化过程。

| Abstract: | By qulitative and quantitative analysis of sporopollen in the deposition of Youlechang drilling,the paper reconstructs primarily the evolution process of paleovegetation and paleoclimate for 2500 years in the area.The result shows that the evolution of vegetation had successive series of typical-grassland,shrub-grassland,forest-grassland and shrub-grassland,the evolution array of the climate was warmer-humid,warmer-dry,more colder-dry,colder-humid and colder-dry. |
