摘　　要：根据所采集的孢粉化石,论述了山西繁峙古近系末期的孢粉植物群特征,建立了三个孢粉组合:(1)Betulaceoipollenites-Taxodiaeceaepolllenites组合;(2)Piceaepollenites-Tsugaepollenites组合;(3)Os mundacidites-Betulaceoipollenites组合。前两个组合反映了早渐新世的植物群面貌;后一个组合则反映的是渐新世中晚期的植物群面貌。反映了在始新世末期到渐新世气候变凉的历程。According to collection of the sporespollen fossils, this article mainly deals with the characteristics of the palynoflora and the sporopollen assemblages succession fossils.It is composed of the following three Assemblages in ascending order and their age are derived. 1.Betulaceoipollenites-Taxodiaeceaepolllenites Assemblage. 2.Piceaepollenites-Tsugaepollenites Assemblage.3.Osmundacidites-Betulaceoipollenites Assemblage. The first two assemblages reflect the early Oligocene flora character and the third middle to late Oligocene,which reflects a process of progressively cooling climate from the Late Eoceme to Oligocene. 
