摘　　要：研究区位于武夷山市星村镇四新村附近区域,以武夷山常绿阔叶林9.6 hm 2森林动态监测样地为试验地,以2018年对森林动态监测样地复查的物种分布及地形因子数据为基础数据;将物种分布与地形因子结合,使用多元回归树(MRT)将样地内群落划分;应用非度量多维标度(NMDS)、相似性分析(Anosim),确认多元回归树群丛划分准确性;应用置换相似性百分比(PER-SIMPER),分析群丛之间差异性和群落构建机制;综合研究结果对武夷山中亚热带常绿阔叶林群丛进行划分。结果表明:样地内群落划分为4个群丛,结合重要值与指示值,群丛命名为群丛A——“红毒茴+檵木-闽楠+福建含笑”群丛(Illicium lanceolatum+Loropetalum chinense-Phoebe bournei+Michelia fujianensis associations)、群丛B——“米槠-毛锥+甜槠”群丛(Castanopsis carlesii-Castanopsis fordii+Castanopsis eyrei associations)、群丛C——“赤楠-米槠+毛锥”群丛(Syzygium buxifolium-Castanopsis carlesii+Castanopsis fordii associations)、群丛D——“樟叶泡花树+凸脉冬青-米槠+少叶黄杞”群丛(Meliosma squamulata+Ilex kobuskiana-Castanopsis carlesii+Engelhardtia fenzelii associations);经非度量多维标度、相似分析表明,4个群丛间差异显著;依据4个群丛的置换相似性百分比分析表明,相对于生态位限制模型和限制扩散模型,生态位-扩散限制模型的E值(零相似性百分比与经验相似性百分比之间的平方偏差之和的对数)较小,说明监测样地群落构建主要受生态位分化与扩散限制两者共同影响。The research area is located near Sixin Village,Xingcun Town,Wuyishan City,taking 9.6 hm 2 forest dynamic monitoring plot of evergreen broad-leaved forest in Wuyishan as the experimental site,and taking the species distribution and topographic factor data reviewed in 2018 as the basic data.Combining species distribution with topographic factors,the community in the sample plot was divided by multiple regression tree(MRT).Nonmetric multidimensional scale(NMDS)and analysis of similarities(Anosim)were used to confirm the accuracy of multiple regression tree associations division;permutation similarity percentage(PER-SIMPER)was used to analyze the differences between associations and the mechanism of community assembly.With the comprehensive research results,the evergreen broad-leaved forest associations in the middle and subtropical zone of Wuyi Mountain was divided.The community in the plot was divided into four associations,combined with important values and indicator values,the four associations were named as Illicium lanceolatum+Loropetalum chinense-Phoebe bournei+Michelia fujianensis associations,Castanopsis carlesii-Castanopsis fordii+Castanopsis eyrei associations,Syzygium buxifolium-Castanopsis carlesii+Castanopsis fordii associations,Meliosma squamulata+Ilex kobuskiana-Castanopsis carlesii+Engelhardtia fenzelii associations.Nonmetric multidimensional scaling and analysis of similarities showed that there were significant differences among the four associations.According to the analysis of the permutation similarity percentage of the four associations,the E value(the logarithm of the sum of square deviations between the zero similarity percentage and the empirical similarity percentage)of the niche-and dispersal-controlled model was smaller than that of the dispersal-controlled model and niche-controlled model,indicating that the community assembly of the monitoring plot was mainly affected by both niche and dispersal-controlled.
