摘  要:对深圳莲花山植被组成及多样性进行了调查研究,5个植物群落共有67科、128属和166种。可见其科的数量较多,每个属所拥有的种也较少,表现出此区域植被组成的遗传差异较高。各群落在种类α-多样性D_s、H、丰富度R_1、R_2及均匀度J值的大致的顺序为群落3和4最高和次高,群落5最低;而群落3和4为自然恢复和半自然恢复的林地,其他3群落为人为干扰较多的群落,其中,群落1受到人为干扰明显强,群落5为较明显的人工林地。因此,对于究竟是人为干扰的群落还是自然恢复的林地群落植物多样性高的争论而言是一个很好的佐证和参考。科的多样性指数D_f值顺序表现为群落5和3的多样性最高,而群落2处在中间地位,群落4最低。属的多样性指数D_g值表现为群落5和3较高,群落1最低。同时表现出各群落里科的多样性较高,而属的多样性较低;在综合多样性系数D_c值方面,其大小顺序为:群落3>群落4>群落2>群落5>群落1。表明2个处在自然和半自然恢复的植物群落其科、属和种的多样性比受到不同程度人工干扰的3个群落的多样性高。在α-多样性方面,与深圳其他山地和部分公园的植物多样性相比,莲花山的植物种类多样性基本处于中等水平,但在各群落内的灌木层及草本植物方面显得比其他地区的明显高。与部分其他国家的山地植物群落的植物物种多样性相比,则基本处在偏高的水平,说明深圳莲花山的植物物种等级的多样性整体处于中等偏高的状态。而在各群落之间科、属的β-多样性系数方面,莲花山各群落之间的系数值都明显高于其他区域的山地自然群落,而比少部分人为干扰较多或者人工经济林的偏低。说明其整个区域的科及属的多样性还是处在偏低的水平。Absract:This paper elaborates the investigation on vegetation composition and plant diversity of Lianhua Mountain of Shenzhen, China. In the 5 communities, there are 67 families,128 genera and 166 species, visibly that family number is more, every genus has fewer species, showing that the genetic difference of region vegetation composition is higher. In aspects of α-specify diversity Ds,H,richness R_1,R_2 and evenness J, community 3 is ranking the highest and community 4 the second-highest, while community 5 the lowest. The community 3 and 4 are natural restoration or half natural restoration forest, the other 3 communities are artificial disturbed communities, and community 5 is more obvious artificial disturbed forest.The natural restoration community possesses higher plant diversity. The order of family diversity Dfis community 5 ranking the highest and community 3 the second-highest, while community2 is in the middle position and community 4 in the lowest. The order of genus diversity index(D_(g1)) is community 5 ranking the highest and community 3 the second-highest, while communi-ty 1 the lowest. Meanwhile, it shows that in all communities, family diversity is higher than that of genus. The order of comprehensive diversity index(D_c) is community 3 〉community 4 〉community 2〉 community 5〉 community 1, showing that the diversities of family,genus and species of the 2 natural or half natural restoration communities are higher than other 3artificial disturbed communities. In aspect of α-diversity, compared with other communities in hilly areas and parks of Shenzhen, the species diversity of Lianhua Mountain is at the middle level, but its diversity of shrub and herb layer is higher than other areas. Compared with the communities in the mountain regions of some other countries, the species diversity of Lianhua Mountain is basically at upper high level, indicating that plant diversity of Lianhua Mountain is generally at middle to high level. The β-diversity coefficient of family and genus
