湖南德夯风景名胜区荨麻科植物的多样性特征
Urticaceae Plant Diversity in Dehang Scenic Area,Hunan Province
摘要
Abstract
Through field surveys,specimen identification,and literature review,this study investigated the species composition,floristic geographical components,landscape distribution,and functional trait diver-sity of Urticaceae plants in Dehang Scenic Area,Hunan Province.Results showed that a total of 50 spe-cies belonging to 13 genera were recorded in the area,with distinct hierarchical patterns in genus and spe-cies composition,dominated by Elatostema(13 species),Pilea(12 species),and Boehmeria(8 species).The floristic geographical composition was complex and diverse:at the generic level,six distribution types and one variant were identified,primarily characterized by pantropical and tropical Asia to tropical Africa distributions;at the species level,six distribution types and two variants were found,with Chinese endemism and East Asian distributions being dominant,reflecting a distinct subtropical transitional flo-ristic character.Plants of the Urticaceae family are distributed in 11 of the 13 landscape types,mainly concentrated in moist,water-adjacent areas such as riverbank slopes and floodplains.Functional traits showed clear differentiation:nutritional traits were predominantly characterized by alternate leaves,medi-um-sized leaves,herbaceous leaf texture,and pubescent leaf surfaces on both sides;reproductive traits were mainly represented by umbellate clusters and corymbose inflorescences,the flowering period was concentrated from March to October,and the fruiting period was concentrated from August to October.These findings indicate that Urticaceae plants in Dehang Scenic Area are rich in species,possess unique floristic characteristics,exhibit diverse landscape distributions,and show strong adaptation between func-tional traits and habitats,warranting scientific conservation and rational utilization.关键词
