摘要: 本文是对内蒙呼包盆地内二级台地沉积物进行孢粉分析的总结。根据对孢粉资料的分析研究得出,该区二级台地沉积物堆积时期的古植被是由森林草原过渡到荒漠草原,气候由湿凉转向干冷。通过孢粉组合的对比,证明二级台地形成于晚更新世晚期,相当于萨拉乌苏组的地层时代。

Abstract: This paper deals with the results of sporo-pollen analysis of the sediments from second-step platform in the Ho-Bao Basin,Nei Mongol.On the basis of analysis and study of spores and pollens,it is convinced that the vegetation related to the sediments of the second-step platform was transitional one from forest steppe to desert vegetations,and the climate changed from humid and cool to dry and cool climate during the formation of the sediments. Comparison of the sporo-pollen assemblages shows that the second-step platform was formed in Late Pleistocene,which corresponds to the time of formation of Salawusu Group.
