Abstract: In this paper, Rényi diversity profiles were used to order communities in diversity of shrub and herb among stand types and site conditions from 40 permanent plots set by Kunyushan Ecosystem Station and assess the efficiency of this approach. Sample species accounted 92.9% of total species in the reserve with an ACE value of 131.26. Analysis of species accumulation curves indicated that samples were statistically sufficient for analysis. ANOVA analysis suggested that shrub and herb diversity indices under various elevations, slope positions, slope gradients and soil depths were not significantly different, however that ShannonWinner index (F=4.665, p=0002)and Simpson index(F=2.465, p=0.044) were significantly different in various stand types. Rényi diversity profiles also indicated that, by having consistently higher profiles than other stand types, broadleaved stands and coniferbroadleaved mixed stands appeared to have higher species diversity, while the other five stand types, i.e. Pinus thunbergii stands, P. densiflora stands, P. thunbergiiP. densiflora mixed stands, Larix kaempfer/Cunninghamia lanceolata stands, coniferQuercus acutissima mixed stands, could not be ordered in diversity with one another as they had corresponding diversity profiles that intersected. On the other hand, site conditions had obvious effect on diversity. Plots at lower elevation, lower slope position and gradient, soil depth>5 cm and ranging 1-3 cm, had lower species diversity. Thus, Rényi diversity profiles were more intuitive to display some detailed differences of species diversity in communities than that which can not be distinguished by other analysis approaches.
