摘 要 ：采用样方调查法对澳门青洲山白楸(Mallotus paniculatus)+假苹婆(Sterculia lanceolata)+破布叶(Microcos paniculata)群落的种类组成、外貌、结构特征、区系和物种多样性进行了分析,结果表明,1700m2样方中有维管植物70种,隶属于42科65属,其中热带性分布属占90.32%,群落属于南亚热带常绿阔叶林植被类型。群落外貌常绿,生活型以藤本高位芽为主(占22.86%)。群落的物种丰富度Magarlef指数为8.78,Shannon-Wienner指数为2.22,Simpson指数为0.98,均匀度Pielou指数为0.52。群落各层次的丰富度、Simpson指数以及Shannon-Wienner指数均表现为下木层>乔木层>藤本植物>草本层,均匀度表现为藤本植物>乔木层>下木层>草本层,表明下木层中组成的种类较乔木层多,优势树种较乔木层明显。

Abstract:According to extensive fieldwork as the basis for studying the characteristics and spe-cies diversity of the Mallotus paniculatus + Sterculia lanceolata + Microcos paniculata community in llha Verde Hill forest of Macau. The results showed that,70 vascular plant species belong to 65 genera and 42 families in a sampling area of 1700 m~2, and tropical elements predominated, making up of 90. 32%. This community belongs to the subtropical evergreen broad-leave forest and is characterized by evergreen liana phanerophytes (22.86%). The species diversity of the community is relatively poor with the Margalef index of 8. 78, the Shannon-Wienner index of 2. 22 ,the Simpson index of 0. 98 and the evenness index of 0.52. The sequence of species richness index,the Simpson index and the Shannon-Wienner index of every layers of the com-munity is shrub layer > tree layer > liana layer > herb layer, and the evenness index sequence is liana layer > tree layer > shrub layer > herb layer. It showed that there are more kinds of spe-cies in tree layer than that in shrub layer,and the dominant species of shrub layer are more ob-vious.
