| 摘 要： | 为给黄前流域人工林综合治理的进一步实施提供科学依据,对流域内4种人工林群落的植物区系组成和地理成分进行分析,并采用常规生物多样性的调查方法对其物种多样性特征进行了定量研究。结果表明:1)该流域的植物区系比较丰富,占泰山植物区系物种总数的13.02%;2)4种人工林灌木层和草本层的Simpson指数、Shannon-Wienner指数和均匀度指数差异显著,物种丰富度指数差异不显著,草本层发育明显好于灌木层;3)各人工林尚处于演替初期阶段,混交林下多以阴生性植物为主,其他林下植被发育常以禾本科等阳生性植物为主;4)不同人工林物种总体多样性特征分析表明,板栗林总体物种丰富度最低,均匀度指数最大,多样性指数较低,而赤松+元宝槭混交林总体物种丰富度最大,多样性指数也最大,均匀度指数较低,群落总体多样性混交人工林较大而单一林分较小,混交人工林更有利于林下植被的发育和更新。

| Abstract: | In order to offer a scientific theory for the further management of the artificial forest communities in Huangqian watershed,the flora composing and the geography ingredient of four typical forests are analyzed,and the characteristics of species diversity are quantitatively researched by normal investigating method.The results showed that: Firstly,the flora of the watershed was richer which accounts of 13.02% of Tai Mountain flora.Secondly,the difference of simpson index,Shannon-Wienner index and evenness index of shrub and herb layer in four soil and water conservation forest communities was non-significant.But the richness index was significant.The development of herb was better than shrub obviously.Thirdly,each artificial forest community was still in primary stage of succession.The vegetation under artificial mixed forest was mainly shady species and under other forests was mainly sunny species as Herbaceae.Fourthly,the analysis on total species diversity characteristic of four manmade communities showed that the total species richness of Castanea mouissima was the lowest,the evenness index was the largest and the diversity index was smaller,while the total species richness of the man-made mixed forest of Pinus densiflora and Acer truncatum was the largest,it's diversity index was also the largest,but it's evenness index was smaller.The total diversity of artificial mixed forest was larger,while single forest was smaller.Artificial mixed forest was advantageous to development and renewal of vegetation under woody layer. |
