Abstract: Species diversity of a shrub community in Tiantong region , Zhejiang Province was measured by applying Shannon-Wiener diversity index(SW) , Simpson ecological dominance(SN) and evenness index(PW) . The result showed that these indices could effectively reveal the characteristics of species composition for subtropic shrubs. SW value of the shrub layer in Tiantong shrub community (TSC) is higher than that of tree layer in evergreen broad-leaved forest ( EBLF) , but is lower than that of shrub layer in EBLF. SN value of the shrub layer in TSC is lower than that of tree layer in EBLF , but it is higher than that of shrub layer in EBLF.PW value of the shrub layer in TSC is lower than that of both tree layer and shrub layer in EBLF. In addition , restoration measures on how to accelerate the progressive succession of the shrub community were tentatively discussed based on species diversity.
