China has an extremely diverse flora with very high levels of endemism that has given China first place in the Northern Hemisphere in floristic richness.

缤纷的中国植物区系包含着大量的特有种，这使中国成为北半球最富植物多样性的国家。其原因一是土地面积辽阔，植物演化历史时间悠久，气候相对稳定。

It contains entries dealing with various aspects of extant and fossil American plants and fungi, including systematics and floristics, morphology, and ecology, as well as economic botany and general botany (publications dealing with botanists, herbaria, etc.).

On the basis of mega and microfossil records, the flora of Yunnan Province has been studied in order to reveal the Tertiary floral evolution and climatic change.

根据已有大化石和孢粉植物群的研究，从植物区系和类群两个层次上，对云南第三纪植物群发展和气候变迁进行了分析。

There were only 94 vascular plant species, belonging to 50 family and 75 genera. The dominant species in the communities were deciduous broadleaf species Liquidambar formosana, Robinia pseudoacacia, Ailanthus altissima, Acer buergerianum, and Celtis sinensis, evergreen broadleaf species Cinnamomum camphora and Elaeocarpus glabripetalus, and Phyllostachys heterocycla. Robinia pseudoacacia+Cinnamomum camphora community had the highest Shannon-Wiener index (1757) and Phyllostachys heterocycla+Acer buergerianum community had the highest Simpson index (0163), but no consistency was observed between the curves of H and D. For vertical structure, most communities had no significant understory stratification.

结果表明：辰山植物区系以泛热带和北温带占优势，具有典型亚热带和温带成分交汇和南北植物分布交错特征；但保育区内种类单一，维管束植物仅有49科69属94种；主要群落是以枫香、刺槐、臭椿、三角枫和朴树等为优势树种的落叶阔叶林，以香樟和秃瓣杜英等为优势树种的常绿阔叶林，以及毛竹林；物种多样性普遍较低，Shannon-Wiener多样性指数最高为刺槐+香樟群落（1.757），Simpson均匀度指数最高值为毛竹+三角枫群落（0.163）；多样性指数曲线和均匀度指数曲线不具有一致性的变化趋势；多数群落垂直结构中无明显林下分层现象；演替前期的落叶乔木种群后续个体不足。

Extinction and colonization account for the depauperate flora and fauna of islands when compared to the adjacent mainland.

On the distribution type of families, Pantropic type was the dominant (36 families), followed by Cosmopolitan type (34 families), accounting for 31.30% and 29.57% of the total families respectively.

含10种以上的科共15科，单、寡种属共323属，其区系地理成分复杂多样，在植物区系组成中具有重要作用。

We also have studies the fossil record and phytogeographic history of Rhizophoraceae, modern flora and vegetation of Hainan Island.

此外，我们还研究了红树科植物的化石记录及植物地理史，同时研究了海南岛现代植物区系和植被特征。
