拉萨河流域湿地种子植物资源特征OA

To clarify the status of wetland plant resources in the Lhasa River basin,a two-year field survey was conducted from 2022 to 2023.The wetland plants in the Lhasa River basin were classified through literature review and other methods.The results showed that there were 85 species of resource plants belonging to 74 genera and 32 families in the study area.According to resource type,they could be classified into medicinal plants,ornamental plants,multi-purpose plants,and other economic plants,among which there are 73 species of medicinal resource plants belonging to 59 genera and 30 families,accounting for 93.75%,79.73%,and 85.88%of the total families,genera,and species in the study area,respectively.Perennial herbs predominate,with 63 species,accounting for 86.31%of the total number of medicinal plant species.In the classification of medicinal parts,plants with the whole herb used as medicine were the most abundant,with 36 species,accounting for 49.32%of the total number of medicinal plant species.In terms of medicinal effects,heat-clearing drugs were the most abundant,with 32 species,accounting for 43.84%of the total number of medicinal plants.The study documented 52 ornamental species(23 families,45 genera),representing 45.61%of the regional flora.Floral ornamentals(39 species)constituted the majority(75%).Conversely,species with ornamental value in foliage,color,or habit were marginal(6,3,and 1 species,respectively).Additional utility types(e.g.,edible,melliferous,oleaginous,aromatic,and pulping)were also sparsely distributed.
