Abstract

Abstract: 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 evely niana 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 div ided into fore association types by means of hierarchical cluster analysis: Assoc. P. keteleeria evelyniana - heteleeria evelyniana + Camellia oleifera - Ageratina adenophora ;Assoc. P. keteleeria evelyniana - Camellia oleifera - Ageratina adenophora ;Assoc. P. heteleeria 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 change. Effect of numerical size by association coverage,existence time and position. Time series analysis show that the strong growth trend of Keteleeria evelyniana populations in next a period of time. So Keteleeria evelyniana community in the overall development stage.

Key words: Keteleeriae evelyniana, association, species diversity index, community, Time Series model
