摘　　要：[目的]通过野外调查蒙山自然保护区野生木本植物资源,分析植物的科属组成和区系成分,为该地区木本植物资源的保护与利用提供科学依据。[方法]2022年1月至2023年12月,采用样线法进行调查,在结合野外调查和查阅参考文献的基础上,对野生木本植物区系科、属的组成和地理成分进行研究。[结果]研究区野生木本植物共计69科136属282种,区系成分复杂,科的分布区类型有9个分布型和5个变型,属的分布区类型有13个分布型和4个变型,综合科属的分布类型,该区域以北温带分布为主,泛热带成分也有明显渗入,这可能与该区域复杂的生态地理环境相关。[结论]蒙山保护区木本植物区系具有一定的古老性,区系分析发现温带成分处于优势地位,但也有泛热带成分的渗入,这可能与该研究区的自然地理环境相关。[Objective]To investigate the wild woody plant resources in Mengshan Nature Reserve through field surveys,analyze the composition of plant families and genera,and provide scientific basis for the protection and utilization of woody plant resources in the region.[Method]From January 2022 to December 2023,a survey was conducted using the transect method.Based on field investigations and reference literature review,the composition and geographical elements of the wild woody plant flora families and genera were studied.[Result]The results showed that there were 282 species belonging to 69 families and 136 genera of woody plants in Mengshan Mountain.The geographical elements of the flora were complex.There were 9 areal-types and 5 subtypes of the families,13 distribution types and 4 variations in the distribution area of the genus.The comprehensive analysis showed that the main geographical composition was the north temperate along with the pantropical elements.This phenomenon was related to the ecological geography of the Mengshan Mountains and indicated a complexity of flora in the study area.[Conclusion]The results indicated that woody flora of Mengshan Reserve was ancient to a certain extent,the floristic element analysis showed that temperate components were dominant,but there were also pantropical components,which might be related to the natural geographical environment in this area.
