TÓM TẮT
This study clarified the biodiversity, ecology and utilization of wild edible plants in the biosphere reserve Cham Island, Hoi An, Quang Nam Province. Using the research methods of quantitative analysis (identification of index), biological diversity (biodiversity measurement): Shannon Index - H (Shannon index), Simpson index - Cd (Concentration of Dominance), Abundance - A and frequency - F of each species. These methods have been applied to assess the biodiversity of plants used as vegetable. This study implemented 20 plots survey and recorded 43 plant species, belonging to 30 families, in different habitats such as: evergreen forests, woodlands scattered sparse, shrub - grassland, bare land, fields and along streams. H index ranged from 0.46 to 1.94 with average value about 1.28 is the lowest in evergreen forest habitats (0.69 -1.46), scattered sparse woodlands (1.15 to 1.53), grass, shrubs (1.35) and vacant land, rice fields, along streams (0.46 to 1.94). This study was aimed to create a database solution for the conservation, development and planning sustainable use of biodiversity resources.
