中文摘要:
      为了解丹寨县木本植物区系特征,采用随机踏查和典型线路调查法进行野外调查,分析该县 木本植物种类组成及科、属的区系特征。结果表明,丹寨县木本植物资源共113科361属1 056种。 其中,裸子植物9科21属30种,被子植物104 科340 属1 025 种,野生木本植物104科328属948种。 从科的组成上看,以蔷薇科(Rosaceae)、樟科(Lauraceae)、豆科(Fabaceae)为优势科,寡种科和中等科 为主体;从属的组成上,以寡种属和单种属为主体。该县木本植物的科、属区系上分别有8个分布类 型和12个分布变型、14种分布类型和3个分布变型;科和属的区系特征均表明该县木本植物区系以 热带分布占优势,且属表现出一定的热带向温带过渡特征。古老孑遗植物较多,且中国特有成分占比 较大。丹寨县植物种类丰富,区系分布类型多样且具有热带和热带向温带过渡的特性。
英文摘要:
      To understand the floristic characteristics of woody plants in Danzhai County, field surveys were conducted using random sampling and typical transect methods, and the species composition as well as the floristic characteristics at the family and genus levels were analyzed. The results showed that there are 1056 species of woody plants belonging to 361 genera and 113 families in Danzhai County, including 30 species of gymnosperm belonging to 21 genera and 9 families, and 1 025 species of angiosperms belonging to 340 genera and 104 families. Among them, 948 species belonging to 328 genera and 104 families are wild woody plants. At the family level, the dominant families are Rosaceae, Lauraceae, and Fabaceae, with oligotypic and intermediate families being the majority. At the genus level, oligotypic and monotypic genera dominate. The floristic composition of woody plants in the county includes 8 distribution types and 12 subtypes at the family level, and 14 distribution types and 3 subtypes at the genus level. Both family and genus floristic characteristics indicate a predominantly tropical distribution pattern, with genera showing transitional features from tropical to temperate zones. The area harbors numerous ancient relict plants, and a significant proportion of species are endemic to China. Danzhai County exhibits rich plant diversity, with diverse floristic distribution patterns characterized by tropical and tropical-to-temperate transitional features.
