| 摘 要： | Through sample plot survey and statistic analysis, this paper adopts ecological method to study the characteristics of plant diversity of forest vegetation in Luofu Mountain, Guangdong. The results show that there is a great plant diversity of forest vegetation in Luofu Mountain owing to the ascendancy of aqueous and thermal condition in subtropical zone. The total number of species in 4 500 m^2 sample plot（s） are 170 with 3 870 individual plants in total; Dahl species richness index （D） is 44.932; Simpson diversity index （L,D） is 0.022, 0.022; Simpson （1982） diversity index （D） is 3.806; Pielou evenness index （E） is 0, 984 and Hulbert evenness index （E） is 0.815; Shannon-wiener diversity index （information index H′） is 4.188; Asymmetry index （r） is 0.185. These indexes show that a better habitat will bring about plant diversity of forest vegetation, and the diversity of zonal vegetation shows that the higher latitude is, the less species of vegetation can be found. Besides, vertical change of plant diversity of forest vegetation in Luofu Mountain is obvious. Its species richness index and plant diversity index show that monsoon evergreen broad-leaved forest is the tallest, mountain evergreen broad-leaved forest follows as the second and conifer-broad-leaved mixed forest is the shortest. The Wilson β-diversity index, which is obtained by comparison between forest vegetation below 300 m and forest vegetation between 600-900 m, is 0.621. Calculated from comparison between forest vegetation in 600-1 100 m and forest vegetation in 900-1 100 m, the Wilson β-diversity index is 0.727; by comparing forest vegetation below 300 m with forest vegetation in 900-1 100 m, the Wilson β-diversity index is 1.877. This shows that the plant diversity of forest vegetation is affected by the change in gradient of elevation.
