采用样方调查法对深圳仙湖植物园马占相思（ Acacia mangium）群落特征和物种多样性进行调查分析。结果表明，在3200 m2的样地中，共有维管束植物58种，隶属于35科49属，整个群落的物种丰富度指数Margalef指数为7.4428，Shan-non-Wiener指数为3.6308，Simpson指数为0.8433，均匀度指数为0.8980，该群落的层次格局为灌木层＞草本层＞藤本层＞乔木层，成层现象较为明显；该群落是以马占相思为主的单优种群落，群落种类组成多样性和水平分布不均匀，其外貌终年常绿，种群处于退化状态。在尊重原有自然植被的前提下，提出仙湖植物园内的面状风景林植被提升改造策略，从而恢复仙湖植物园地域性的季风常绿阔叶林植物景观。

The characteristics and species diversity of the Acacia mangium community at Fairylake Botanical Garden in Shenzhen, were studied by quadrat survey.The results showed that there are 58 species of vascular plants belonging to 35 families in the sample plots totaling 3200 m2.The species diversity of the community is relatively low with Margalef index of 7.4428,Shannon-Wiener index of 3.6308,Simpson index of 0.8433,and the evenness index of 0.8980.The diversity pattern from maximum to minimum is ordered by shrub,herb,liana and arbor.Litsea glutinosa is the dominant species of the community and its composition diversity and horizontal distribution is uneven.The analysis on species important value and frequency showed that the physiognomy of the community was ev-ergreen.The age structure of dominant population showed that the main population of the community belongs to rudimentary popula-tion.On the premising the respect for the original natural vegetation, this paper puts forward a improve transformation strategy for fairy lake botanical garden planar scenic forest vegetation to restore the fairy lake regional monsoon evergreen broad-leaved forest bo-tanical garden plant landscape and highlights the features for fairy lake botanical garden plant landscape.
