| 摘 要： | 采自凤州和商州两地黄土剖面中６５组孢粉样品分析结果表明，黄土层中的草本植物花粉含量相对较古土壤层中者为高，而木本植物花粉含量相对较古土壤层中者为低。从孢粉组合来看，秦岭黄土堆积时的植被一般为森林草原型原森林型，气候较寒冷但偏湿，古土壤发育时的植被一般为夏绿阔叶林型，反映出暖温带气候。显而易见，无论是黄土堆积时期还是古土壤发育时期，秦岭山地的气候都较黄土高原地区湿热。

| Abstract: | There have been abundant fossils of sporopollen in loess and paleosol in the Qinling Mountains.The contents of herb pollens in loess layers are more than those in paleosol layers,while woody plant pollens are mainly distributed in the paleosol layers.The sporopollen assemblages show that loess was deposited under forest steppe or steppe forest vegetation,the climate was cold and somewhat humid,and paleosol developed under summer green broadleaf forest vegetation of humid warm climate.It is quite evident that the paleoclimate in the Qinling Mountains is more humid warm than that in the Loess Plateau during the Quaternary. |
