摘要
云南的思茅松林为我国云南省重要的战略森林资源,但其植物资源多样性未见系统报道,为揭示其区系特征及群落外貌,本研究基于144个群落调查样方数据,分析了云南的思茅松林的维管植物区系、生活型与叶相特征。结果显示:(1)云南的思茅松林群落维管植物经合计共130科440属800种,其中包括蕨类植物18科36属61种,裸子植物2科4属7种,被子植物110科400属732种,优势科为豆科、壳斗科和禾本科,优势属为榕属、锥属和柯属。(2)科属的地理成分均以热带成分占优势,且均以泛热带成分为主;温带分布型以北温带及其变型为主。未见中国特有科,中国特有属9种。寡种和单种科属占比高,一定程度表明了该群落类型对生境选择的多样化响应。从演化趋势来看,古老成分与新生类群共存。(3)生活型谱中高位芽植物为该群落优势生活型,占比为61.25%,Raunkiaer生活型谱呈“L”型。(4)植物叶相以纸质(44.00%)、单叶(74.50%)、全缘(67.75%)、中型叶(46.38%)为主。该研究结果有助于进一步认识思茅松林区系特征、为其生态保护和管理提供参考价值。
Pinus kesiya var.langbianensis is an important strategic forest resource in Yunnan province of China,but its plant resource diversity has not been reported systematically.In order to reveal its flora characteristics and community appearance,this study based on the data of 144 community survey plots,the vascular flora characteristics,life form and leaf phase of P.kesiya var.langbianensis forest in Yunnan were analyzed.The results showed that there were 800 species,440 genera,and 130 families,recorded,in surveyed plots,including 61 species,36 genera,and 18 families of ferns,7 species,4 genera,and 2 families of gymnosperms,and 732 species,400 genera,and 110 families of angiosperms.The dominant families were Fabaceae,Fagaceae and Poaceae.The dominant genera were Ficus,Castanopsis and Lithocarpus.The geographical composition of the families was dominated by tropical components,and all of them were pantropical components.And the temperate distribution type was mainly north temperate zone and its variant type.There was no Chinese endemic family recognized,and 9 genera were endemic to China.The high proportion of oligotypic and monotypic genera indicated diverse response of the communities to varied habitat filtering.Cooccurence of the ancient flora and new taxa were found in the communities investigated.Raunkiaer’s life form was of‘L’shape,and the phaenerophyte was the dominant type,accounting for 61.25%.The plant leaf phase were mainly in papery(44.00%),single leaves(74.50%),entire(67.75%),mesophyll(46.38%).This results of this study was helpful to further understand the forest flora characteristics of P.kesiya var.langbianensis and provide reference value for its ecological protection and management.
