Species compositions,diversity indexes of plant in green space in Meishan Mountains of Donghu Lake in Wuhan City were analyzed by adopting typical sampling method.Result show that:there are 21 families,29 genera, 34 species in plant in green space of Meishan Mountains of Wuhan City.The floristics in the west and north of the Meishan Mountains are larger than that in eastern and southern of the Meishan Mountains ;Simpson index (D ), Shannon-Weiner index (H )and Pielou index (J )show the same trend,namely the index value of trees> index val-ue of shrubs > index value of herbs;among the plant in Meishan Mountains,the trees whose important values being greater than 10% have nine species,and the shrubs whose important values being greater than 10% have five spe-cies.
