摘 要:云南松杉类植物是构成云南山地森林生态系统的主要林木树种,种质资源丰富,通过研究其植物区系资源优势的特性及意义,总结如下:云南本土产6科、25属、96种松杉类树木,居各省(市)域之首,也是世界它地难觅的;列出了现有的(含引种的)松杉类植物,其8科、39属、195种的分类系统,是半个多世纪努力保护开拓的结果。用植物区系的观点分析种属的珍、稀、古、特的性质和意义;从属的区系类型及组合分析它们的多样性,与相关的地史变迁、生态地理区域及环境交接过渡的变化与意义;简析了云南松杉类树种丰富多样的因果关系。Conifers are the main tree species in the mountainous forest ecosystem of Yunnan Province,which are rich in germplasm resources.Through the study of the characteristics and significance of the dominant flora,the resources are summarized as follows:there are 96 species of conifers belonging to 25 genera and 6 families in Yunnan Province,which ranks first in China and is also rare in the world;the study lists the existing(including extended)conifers species,the classification system of 195 species,39 genera and 8 families of conifers is the result of more than half a century of efforts in the protection and development of conifers.The characteristics and significance of valuable,rare,ancient and special of species and genera are analyzed from the viewpoint of flora;the change and significance of diversity with the related geohistory,ecogeography and environment were analyzed use the genus types and combinations;the causal relationship of the richness and diversity of conifers was analyzed.
