摘  要:
为探究滇中高原滇油杉群落多样性及种群时序变化,采用典型抽样法对昆明市金殿云南森林自然中心滇油杉(keteleeria evelyniana)群落进行调查与分析,结果表明滇油杉林群落共有种子植物70种,隶属38科63属。以乔木层主要物种的重要值作为聚类变量,通过系统聚类分析得到4种群丛类型:滇油杉-滇油杉+油茶-紫茎泽兰林,滇油杉-油茶-紫茎泽兰林,滇油杉-油茶+小铁子-紫茎泽兰+地石榴林,滇油杉-小铁子-紫茎泽兰林。总体来看,各个群丛的Shannon多样性指数、Simpson优势度指数、Pielou均匀度指数和Margalef丰富度指数的数值的大小和群丛盖度、存在时间及所处位置有关。时序分析表明,滇油杉在未来的一段时间中呈强烈增长趋势。可知目前滇油杉群落处于稳定发展的状态。

摘  要:
In order to explore species diversity and population temporal variation of Keteleeria evelyniana community in Yunnan plateau,Keteleeria evelyniana community of Yunan Forest-Nature Center Jindian Kunming were investigated and analyzed by typical sampling method. The results show that Keteleeria evelyniana forest communities in the investigation of the total 70 species of seed plants,belonging to 38 families and 63 genera. Taking the important value of main treespecies of arbor layer as clustering variables,the P. keteleeria evelyniana community could be divided into four association types by means of hierarchical cluster analysis: Assoc. P. keteleeria evelyniana- keteleeria evelyniana + Camellia oleifera- Ageratina adenophora,Assoc. P. keteleeria evelyniana- Camellia oleifera- Ageratina adenophora,Assoc. P. keteleeria evelyniana- Camellia oleifera + Myrsine africana- Ageratina adenophora + Ficus tikoua,Assoc. P. keteleeria evelyniana- Myrsine africana- Ageratina adenophora. Overall,each cluster Shannon diversity index,Simpson dominance index,Pielou evenness index and Margalef richness index have obvious changed. Effect of numerical size is related to association coverage,existence time and position. Time series analysis shows that the strong growth trend of Keteleeria evelyniana populations happens in the next period of time. So Keteleeria evelyniana community is in the overall development stage.
