The community structure and species diversity of the Castanopsis eyrei forests in Wuyishan National Park were studied to provide a scientific basis for biodiversity conservation and ecological restoration in the region.Surveys conducted in 2018 and 2023 analyzed aspects such as species composition,importance values,diameter at breast height(DBH)classes and tree height structures,species diversity,and floristic characteristics.Results indicate that over five years,the number of tree layer species increased,while the number of individuals decreased;both the number of species and individuals in the shrub layer declined,as did the number of herb species.There was no significant change in the importance values of species within the community,with Castanopsis eyrei remaining the dominant species in the tree layer,whereas the dominant species in the shrub and herb layers changed.The distribution of individuals across DBH classes and tree heights exhibited a reversed"J"shape.Over the five years,the species diversity of the tree,shrub,and herb layers increased,with the shrub layer showing higher species diversity than the tree and herb layers.The floristic components of the community were complex,reflecting a degree of ancientness and significant tropical characteristics.The R/T ratios of families and genera decreased during this period.In summary,while changes occurred in community structure and species diversity of the Castanopsis eyrei forest in Wuyishan National Park,stability was maintained over the five years.
