Diversity and Floristic Characteristics of Seed Plants in Daping Mountain Nature Reserve,Guangxi
摘要
Abstract
Through field investigations and literature review,this study comprehensively documented the current status of wild seed plant resources and analyzed floristic characteristics in the Dapingshan National Nature Reserve,Guangxi,aiming to provide scientific basis for biodiversity conservation and sustainable utilization.Key findings included:① the plant species exhibited rich diversity,with 1017 known species of seed plants belonging to 137 families and 529 genera.Among these,tree species predominated,followed by herbaceous species.② Family composition showed dominance by small-sized families,with 56.20%containing 2～10 species and 24.09%being monotypic.At generic level,62.57%were monotypic and 31%contained 2～4 species.③ Floristic analysis revealed 10 family areal-types with 4 subtypes,dominated by pantropical elements(38.69%),showing a tropical vs.temperate floristic ratio(R/T)of 3.42.Generic distribution exhibited 13 types with 14 subtypes,dominated by pantropical(22.68%)and tropical Asian elements(16.64%),yielding an R/T ratio of 4.07.④ The reserve was home to 55 key conservation species,including 21 Orchi-daceae species(38.18%).Comparative analysis indicated close floristic affinity with neighboring Damingshan Nature Reserve.The flora demonstrated distinct tropical characteristics with ancient origins.These findings highlight the reserve's significance in maintai-ning biodiversity and conserving paleoendemic flora.关键词
