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。

The results were summarized as follows:1 Four cpDNA trnL-F, matK, rbcL, and atpB sequences analysis The chloroplast trnL-F, matK, rbcL, and atpB sequences from 31 species representing nearly all genera of Fagales (sensu APG, 2003) were used to reconstruct the phylogeny of the order.
主要内容包括:1 基于四个叶绿体DNA序列的分析以金缕梅属Hamamelis和朴树属Celtis为外类群,对壳斗目几乎所有属的代表共31种植物的trnL-F、matK、rbcL和atpB序列进行了测定,通过四个序列单独和联合分析,得到如下结果:除rbcL基因树由于信息位点少而分辨率较低之外,壳斗目各科作为单系类群在各种分析中都得到了较强的bootstrap支持。
