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.展开更多

The results showed that Yunfeng Mountain had a high diversity in seed plants, which covered 92 families, 247 genera and 431 species. Among the seed plants, the gymnosperms covered 4 families, 5 genera and 7 species, while the angiosperms covered 88 families, 242 genera and 424 species. The seed plants in Yunfeng Mountain had rich distribution types, and they formed a flora dominated by tropical and subtropical plants.展开更多

The results showed that there were 41 families, 99 genera and 164 species of seed plants. The top families distribution types were cosmopolitan and north temperate ones, while the main genera distribution types were north temperate and cosmopolitan ones, and the proportion of the temperate ones was higher than the tropic ones, which showed that the north temperate elements were dominant in floristic composition. In this area, the species were lack, and herbaceous plants had a distinct advantage, showing a characteristic of the vegetation.展开更多

Comparative analysis of the diversity of the subnival flora on different types of stone and at different altitudes in various parts of the Caucasus has been made. It is based on field investigation and on literature research. 226 species, 96 genera and 35 families were recorded in the subnival belt of the Caucasus within a range of 2,800 （2,900）-4,000 m a.s.l. Among these 117 species or 51% are common endemics of the Greater Caucasus and Caucasus. It is proved that floristic elements of different origin （authochronic and aloctonic） and age （Miocene-Pliocene and Pleistocene） contributed to the florogenesis of the subnival belt of the Caucasus. The Caucasian, the Eu-Caucasian, the Eastern Asian, the Minor Asian, the Dagestan-lranian, the Caucasia-European groups plaied an important role in the florogenesis. Criophilic evolution on the of the some plants was related to oreophytizacion during formation of the Caucasus mountains （in the second half of the Tertiary）, as well as the glaciations scale. Species composition and coenotic role are different in various parts of the Caucasus and within each part. This is conditioned by the different hypsometry of various parts of the Caucasus, the character of glatiations, edaphic and climatic conditions, lythological diversity. Compared with the Greater Caucasus, the relative floristic poverty of the Lesser Caucasus is due to low elevations and extensive rather recent vulcanism.展开更多
