黔东南马尾树群落特征调查分析

[目的]调查黔东南马尾树群落的物种组成、外貌及结构特征,为制定其合理的保护措施提供参考依据。[方法]在黔东南选择代表性地段,设置马尾树群落样方,调查其乔木层、灌木层、草本层物种组成,乔木层树高、胸径,灌木层、草本层盖度和高度等,分析其群落特征。[结果]群落中生长维管束植物103种,分属61科85属,科属组成较复杂。103种植物的区系地理成分丰富多样,以热带成分占优势,并含有较多古老属种。群落外貌以中、小型草质单叶的高位芽植物占优势,占103种植物的84.41%,中、小型单叶占103种植物的91.26%;落叶成分所占比例稍高于常绿成分,分别为55.34%和44.66%。群落垂直结构分化较明显,可...

Summary:[目的]调查黔东南马尾树群落的物种组成、外貌及结构特征,为制定其合理的保护措施提供参考依据。[方法]在黔东南选择代表性地段,设置马尾树群落样方,调查其乔木层、灌木层、草本层物种组成,乔木层树高、胸径,灌木层、草本层盖度和高度等,分析其群落特征。[结果]群落中生长维管束植物103种,分属61科85属,科属组成较复杂。103种植物的区系地理成分丰富多样,以热带成分占优势,并含有较多古老属种。群落外貌以中、小型草质单叶的高位芽植物占优势,占103种植物的84.41%,中、小型单叶占103种植物的91.26%;落叶成分所占比例稍高于常绿成分,分别为55.34%和44.66%。群落垂直结构分化较明显,可分为乔木层、灌木层、草本层和层间植物层,树冠分布较连续。[结论]黔东南马尾树群落是一个受破坏后形成的处于恢复演替中的次生植被群落,在密林下难以更新,需外界干扰造成一定林窗面积才能获得更新机会;加强对黔东南马尾树的引种驯化工作,有利于其保护和开发利用。

[Objective]The species composition,physiognomy and structural features of Rhoiptelea chiliantha commu- nity in southeast of Guizhou province were investigated to provide references for formulating reasonable protective mea- sures. [Method]By selecting representative areas in southeast of Guizhou province and setting community plots of R. chiliantha,the species composition of arbor, shrub and herbaceous layers, height and diameter of arbor layer and coverage and height of shrub and herb layers were investigated. Based on these acquired data, the community＇s characteristics were analysed. [ Result ]The results showed that a total of 103 species of vascular plants were in R. chiliantha community in southeast of Guizhou province,belonging to 85 genera and 61 families. And the analysis on floristic geographical elements of these communities indicated that the areal-types were compli
