新疆车排子地区孢粉植物群与古气候

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Piceapollis－Podocarpidites－Tsugaepollenites, Parajunggarsporites-Piceaepollenites, Protohaploxypinus-Striatoabieites-Hami-apollenites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。

Based on the analysis of samples from multiple exploration wells in the Chepaizi area, northwestern margin of the Junggar Basin, Xinjiang, abundant sporopollen fossils were identified, and three sporopollen assemblages were established: Piceapollis－Podocarpidites－Tsugaepollenites, Parajunggarsporites-Piceaepollenites, and Protohaploxypinus-Striatoabieites-Hamiapollenites. Based on the morphology and ecological characteristics of the sporopollen's parent plants, as well as the aridity-humidity conditions and climatic environments, we classified the vegetation types, aridity-humidity categories and climatic zone types reflected by this sporopollen flora. It is determined that the sporopollen-based vegetation during the Late Miocene was coniferous forest, with the corresponding climatic environment being humid warm temperate zone; during the Early Cretaceous, the sporopollen vegetation was mixed forest, with the corresponding climatic environment being humid subtropical-warm temperate zone; during the Late Carboniferous, the vegetation was dominated by broad-leaved plants, with the corresponding climatic environment being semi-arid warm temperate zone.
