| 摘要: |
| 为了揭示广东7 种典型的植被型植物多样性的差异及其规律。从广东省森林资源连续清查固定样地中抽取267 个有林地的固定样地开展植物多样性调查调查，以Margalef 指数作为物种丰富度指标、以Shannon-Wiener 指数作为物种多样性指标、以Pielou 指数作为均匀度指标对每种植被型的乔木层、灌木层和草本层进行植物多样性评价。结果显示：乔木层的丰富度指数、多样性指数和均匀度指数总体呈现出常绿阔叶林＞常绿落叶阔叶混交林＞暖性针阔混交林＞热性针阔混交林＞暖性针叶林＞热性针叶林＞阔叶林型（人工植被）；灌木层的丰富度指数、多样性指数和均匀度指数总体表现为常绿落叶阔叶混交林＞热性针阔混交林＞暖性针叶林＞暖性针阔混交林＞常绿阔叶林＞阔叶林型（人工植被）＞热性针叶林；草本层的丰富度指数、多样性指数和均匀度指数总体趋势为热性针阔混交林＞常绿落叶阔叶混交林＞阔叶林型（人工植被）＞热性针叶林＞常绿阔叶林＞暖性针叶林＞暖性针阔混交林。 |

| Abstract: |
| In order to reveal the plant diversity difference and regularity of seven typical vegetation types in Guangdong province. A survey of plant diversity was conducted in 267 permanent sample plots with forest resources in Guangdong province. The Margalef index was used as the index of species richness, the Shannon-Wiener index
as the index of species diversity, and the Pielou index as the index of evenness to evaluate the plant diversity of
tree layer, shrub layer and herb layer of each vegetation type.The results showed that the richness index, diversity
index and evenness index of tree layer showed evergreen broad-leaved forest ＞ mixed evergreen and deciduous
broadleaved forest ＞ warm mixed plantation of coniferous and broadleaf ＞ thermal mixed plantation of coniferous
and broadleaf ＞ warm coniferous forest ＞ thermal coniferous forest ＞ broad-leaved forest (artificial vegetation);
the richness index, diversity index and evenness index of shrub layer showed mixed evergreen and deciduous
broadleaved forest ＞ thermal mixed plantation of coniferous and broadleaf ＞ warm coniferous forest ＞ warm
mixed plantation of coniferous and broadleaf ＞ evergreen broad-leaved forest ＞ broad-leaved forest (artificial vegetation) ＞ thermal coniferous forest; the general trend of richness index, diversity index and evenness index of
herb layer is thermal mixed plantation of coniferous and broadleaf ＞ mixed evergreen and deciduous broadleaved
forest ＞ broad-leaved forest (artificial vegetation) ＞ thermal coniferous forest ＞ evergreen broad-leaved forest ＞
warm coniferous forest ＞ warm mixed plantation of coniferous and broadleaf. |
