摘　　要：通过对新疆准噶尔盆地西北缘车排子地区多口探井样品分析,见丰富的孢粉化石,建立了PiceapollisPodocarpidites-Tsugaepollenites,Parajunggarsporites-Piceaepollenites,Protohaploxypinus-Striatoabieites-Hamiapollenites三个孢粉组合。根据孢粉母体植物形态和生态特征、干湿度环境和气候环境,对其孢粉植物群反映的植被类型、干湿度类型和气候带类型进行了划分,认为晚中新世孢粉植被类型为针叶林,所处的气候环境为湿润的暖温带;早白垩世孢粉植被类型为混交林,所处的气候环境为湿润的亚热带-暖温带;晚石炭世时期其植被面貌是以阔叶植物为主,所处的气候环境为半干旱的暖温带。This paper presents the palynological assemblages from the Chepaizi area in northwest Junggar basin. Three assemblages have been recognized, including Ⅰ. The Piceapollis-Podocarpidites-Tsugaepollenites Assem blage, Ⅱ. The Parajunggarsporite-Piceaepollenites Assemblage and the Ⅲ. Protohaploxypinus-Striatoabieites-Hamiapollenites Assemblage. Based on ecological characteristic, climate and humidity condition for the vegetation type of the sporo-pollen from the Chepaizi area, the palaeoenvironmental conditions have been reconstructed. The spore-pollen flora of the Late Miocene lived under a humid warm-temperate climate condition with typical acieulisil vae, while the Early Cretaceous under a humid subtropical to warm temperate climate condition with mixed forest; and the Late Carboniferous under a subarid warm-temperate climate condition with broad-leaf forest.
