中国早白垩世植物群按植物地理学划分为北方植物区系省和南方植物区系省。提出了“温湿植被”和“热带-亚热带旱生植被”两种不同植被类型的代表。在这两个植物区系省共发现化石木52种，分属苏铁目（2种）、银杏目（1种）和松柏目（49种），主要分布在东北地区。化石木的生物多样性和解剖学特征，特别是生长轮特征分析表明，早白垩世北方和南方植物区系的气候条件具有季节性变化。这表明早白垩世中国南方可能以热带-亚热带半干旱气候为主，而北方则以暖温带湿润气候为主。木材证据与中国早白垩世相应地层中的叶化石一致。
The Chinese Early Cretaceous flora was divided phytogeographically into the Northern Floristic Province and the Southern Floristic Province. The “temperate–wet vegetations” and “tropic–subtropic xeric vegetations” were proposed to represent the two different vegetation types. About 52 species of fossil woods belonging to Cycadophytes (2 species), Ginkgoales (1 species) and coniferales (49 species) have been discovered in the two floristic provinces, mainly from the Northeast China. The biodiversity and anatomical characteristics, especially the growth ring feature analysis of fossil woods indicated climatic conditions with seasonal variation in both the Northern and Southern Floristic Provinces during the Early Cretaceous. It suggests that a tropic to sub-tropic semi-arid climate might dominate over southern China, while warm or temperate, and wet climate prevailed in northern China during the Early Cretaceous. The wood evidence is in accordance with that of the leaf fossils collected from the corresponding formations of the Early Cretaceous in China.
