摘　　要：为深入研究晋南典型丘陵沟壑区不同林地类型物种多样性,通过比较Margalef指数、Shannon-Wiener指数、Simpson指数、Pielou指数等多样性指标,对人工刺槐林、人工侧柏林和天然次生林进行比较.结果表明:(1)林地内共分布有37种植物,均属于被子植物门(Angiospermae),且林地植物分布以菊科(Asteraceae)、蔷薇科(Rosaceae)为主的双子叶植物纲(Dicotyledons)物种为主.(2)不同林地类型下,人工林地的物种丰富度、多样性、优势度和均匀度普遍高于次生林地.(3)不同林龄的人工林比较,侧柏林物种丰富度均高于刺槐林,但随着时间的推移,刺槐林的优势度和均匀度明显高于侧柏林,其中侧柏林和刺槐林的物种丰富度、多样性、优势度均呈现上升趋势,均匀度呈下降趋势.In order to deeply understand the status quo of species diversity of different forest types in typical hilly and gully regions of southern Shanxi,the artificial Robinia pseudoacacia forest,artificial Platycladus orientalis forest and natural secondary forest,which were mainly composed of forest land,were compared by comparing Margalef index,Shannon-Wiener index,Simpson index and Pielou index.The results showed that there were 37 species of plants in the forest land,all belonged to Angiospermae,and the distribution of the plants in the forest land was mainly Dicotyledons species dominated by Asteraceae and Rosaceae.Under different forest types,the species richness,diversity,dominance and evenness of plantation land was generally higher than that of secondary forest land.The species richness of Platycladus orientalis was higher than that of Robinia pseudoacacia,but over time the dominance and evenness of Robinia pseudoacacia was obviously higher than that of Platycladus orientalis.The species richness,diversity and dominance of Platycladus orientalis and Robinia pseudoacacia rose,while the evenness declined.
