Abstract：We investigated the species composition and species diversity in Daanyuan with 4 800 m2 area, in Wuyishan mountain .There are 97 vascular plant species , belonging to 57genera and 31 families.A-mong them, there are 78 tree species, 8 shrubs, 5 herbs and 6 lianas.The Fagaceae, Ericaceae, Elaeo-carpaceae and Theaceaeare are the dominant families , the Castanopsis, Rhododendr on, Elaeocarpus are the vital genera.Based on the important value ,C.eyrei, R.ovatum, R.latoucheae, E.ajponicas, Syzygi-um buxifolium are the top 5 dominant species .And C.eyrei have a top RBA value of 64.93%.The species-area curve show that specie richness stabilized when sampling area over 4 400 m2 , and the fitted curve was the logarithmic function equation ,y=21.836lnx-87.287( R2=0.990 2) .The trees with DBH less than 5 cm accounted for 76.88%.The deciduous species are accounted for 12.38%of the total species .Simp-son index and Shannon-wiener index of the south slope bigger than north slope .Shannon-wiener index and Pielou index both increased with sampling size , and stabilized at 2 000m 2.C.eyrei evergreen broad-leaved forest in Daanyuan is a typical east asia mid -subtropical evergreen broad-leaved forest .
