| 摘 要： | 根据神农架南坡6800m抽样区的调查结果,珍稀植物群落中有维管束植物126种,隶属于108属64科。其中,第一批珍稀保护植物9种,占神农架地区珍稀植物总数的27.3%,珍稀植物群落具温带特性。群落外貌以高位芽为主,占65.9%;叶以中型叶占优势,达62.7%;叶质以纸质为主,占84.1%;叶型以单型叶为主,为83.3%;叶缘以非全缘为主,占69.8%。群落垂直分层明显,可分为乔木层、灌木层和草本层。根据重要值,珍稀植物群落可分为三种类型,即连香树 涓毛绸李群落、珙桐 木姜子群落、涓毛绸李 地锦槭群落。不同珍稀植物群落乔木层物种多样性变化较小,均匀度较高,表明珍稀植物群落结构的复杂性和群落发展的相对稳定性。表5参8。

| Abstract: | According to the investigation of sampling area of 6800 m2 on the south slope of Shennongjia Mountain, there were 126 vascular plant species, belonging to 108 genera and 64 families, in the investigated rare plant communities, of which 9 rare plant species were recorded, accounting for 27.3% of the total rare plants. The communities were about 30 m in height and were divided into three layers as tree layer, shrub layer, and herb layer. The flora of the communities had obvious temperate character. Phanerophytes (accounted for 65.9%), Mesophyllous (62.7%), Papyraceous (84.1%), simple leaf (83.3%), un-entire leaf (69.8%) were dominant in life form, leaf size class, leaf texture, leaf form, and leaf margin respectively. According to important value of species, the communities were divided into three types as Davidia involucrata Litsea pungens community, Cercidiphyllum japanicum Padus wilsonii community, and Padus wilsonii Acer mono community. The indexes of species diversity of tree layer had little difference among communities and evenness was high. The results indicated that the communities had complex structure and relative stability. |
