陆河新近纪植物群属泛北极地植物群。被子植物是该植物群的主要成分，如桤木属、桦属、鹅耳枥属、榆属、榛属、栎属、青冈属、锥属、山核桃属、栗属、枫香属、Davidia、冬青属、棕榈属等。植被类型为万年青和落叶阔叶林，但在高地附近也有一些针叶林（冷杉、铁杉、松树等）。花粉和孢子的组合反映了温暖湿润的亚热带气候。通过与其他植物群的对比，确定了六合植物群的地质时代为中新世中晚期至上新世早期。
The Neogene flora of Luhe belongs to Holarctic geoflora. Angiosperms are the dominated elements in this flora, such as Alnus, Betula, Carpinus, Ulmus, Corylus, Quercus, Cyclobalanopsis, Castanopsis, Carya, Castanea, Liquidambar, Davidia, Ilex, Palmae, etc. The vegetation type is evergreen and deciduous broad-leaved forest although some coniferous forests (Abies, Tsuga, Pinus etc) are present near the highlands. The assemblage of pollens and spores reflects a warm and humid subtropical climate. The geological age of Luhe ranges from Middle-Late Miocene to Early Pliocene, based on comparison with other floras.
