摘　　要：基于野外调查和文献资料整理,对贵州省铜仁市野生林木种质资源进行分析,发现铜仁市野生林木种质资源丰富,有114科416属1812种,其中国家重点保护野生植物38种(国家一级5种,国家二级33种),省级重点保护野生植物18种;被子植物在物种组成中占据绝对优势,其中双子叶植物又是被子植物的主要成分;单种科、单种属分别占14.04%、39.91%,科属组成复杂,优势科属明显。从植物区系分布来看,科的区系分布以世界分布、泛热带分布和北温带分布为主,属的分布中热带属占据绝对优势。研究结果可为铜仁市野生林木种质资源的保护和开发利用提供参考。Based on field investigations and literature review,an analysis was conducted on the wild forest germplasm resources in Tongren City,Guizhou Province.It was found that Tongren City has abundant wild forest germplasm resources,with 1812 species belonging to 416 genera in 114 families.Among them,there were 38 species of nationally protected wild plants(5 species at national level I and 33 species at national level II)and 18 species of provincial-level protected wild plants;angiosperms dominated the species composition,with dicotyledonous plants being the main component of angiosperms;single species families and genera accounted for 14.04%and 39.91%,respectively,with a complex composition of families and genera,and a clear dominance of dominant families and genera.From the distribution of plant flora,the distribution of families was mainly dominated by world distribution,pan tropical distribution,and northern temperate distribution,with tropical genera occupying an absolute advantage in the distribution of genera.The research results can provide reference for the protection and development of wild forest germplasm resources in Tongren City.
