%X The tropical montane rain foreston Wuzhi Mountain,Hainan has abundant species.In a 1hm 2 there are 54 families,100 genus,177 plant species and 1337 individuals.The result of a floristic geographical study shows the major types of genus are tropical components(89.0%).It fully reflects the tropical characteristics of the montane rain forest on Wuzhi Mountain,Hainan.The result of diversity indices shows that in plot 1,Margalef index is 17.822,Shannon Wiener index is 5.900,evenness is 0.859,Simpson index is 0.028,evenness is 3.866.In plot 2,Margalef index is 17.381,Shannon Wiener index is 5.621,evenness is 0.823,Simpson index is 0.050,evenness is 6.775.It reflects that the tropical montane rain forest has high species diversity and high evenness,and the diversity of a low elevation plot is higher than that of a high elevation one.Fourty four singleton and 25 doubleton,respectively accounting for 24.9% and 14.1% of the total species number,are identified in the plots.These species with a low density and small population are more declined to extinct than the dominant species under any disturbance.The loss of the singleton and doubleton species will lead to a low species diversity in the community.
