Abstract:

The paper aims to explore the characteristics of medicinal plant resources and the floristic composition of medicinal plants in Lingdong District of Shuangyashan City and their genetic relationship with plants floristic composition in adjacent areas. The research was carried out based on the Fourth National Survey of Traditional Chinese Medicine Resources and the theory of plant geography. There were 272 species of medicinal vascular plants belonging to 71 families and 199 genera in Lingdong, which were dominated by angiosperms. In the composition of families and genera, single species family, oligotypic family, monotypic genus and oligotypic genus constituted the main body of plant resources in this area. Perennial herbs were the main form. Whole herbs were the main medicinal parts. 36 species were investigated, and the total reserve was 1808736.85 kg. The floristic components of seed plants were rich, mainly temperate components, and many components coexisted. The R/T value of Lingdong was the lowest and the temperate components were the highest. The results of cluster analysis showed that the genetic relationship between Lingdong and Hegang was the closest. The wild medicinal plant resources are rich in Lingdong, the geographical elements of life form, medicinal parts and families and genera are obviously diverse, and the floristic affinity is affected by many factors.

Key words: Lingdong District, medicinal plant, reserves, geographical element, cluster analysis
