Abstract:

This paper elaborated species diversity and characteristics of plants community in Guimengding of Mengshan National Forest Park by taking quadrat survey method. The results showed that 43 kinds of vascular plants were recorded in four plots (total 1 600 m²), which belonging to 18 families and 31 genera. Community vertical structures of the four plots were obvious, which could be divided into tree layer, shrub layer and herbaceous layer, with different major species including Quercus variabilis, Vitex negundo var. heterophylla and Commelina communis respectively. From the average value of species diversity index, species richness (S), diversity (H'), evenness (E), dominance (D) showed that the order from big to small is herb layer,shrub layer and tree layer. However, there were certain differences in species diversity at the same level of the 4 plots. It is suggested that the dominant plant species should be protected, and the development of diversity of plants community should be strengthened at the same time so as to promote the ecology function of the plants community in Guimengding of Mengshan National Forest Park.
