中国野生唇形科物种多样性及其地理格局分析OA

Based on the taxonomic database and a large amount of literature,this study takes administrative counties as the basic unit to sort out the wild Lamiaceae distributed in Chinese Mainland.The species diversity,genus flora,and distribution were analyzed,resulting in the establishment of a geographical distribution dataset for wild Lamiaceae in China.As of January 2024,100 genera and 1,387 species(including subspecies and varieties)were recorded.Among these,only Scutellaria,a genus with more than 150 species.The genera with species numbers between 101 and 150 include Salvia with 137 species and Isodon with 106 species.Thirty-six genera contain between 6 and 50 species,totaling 733 species,representing the main component of wild Lamiaceae in China.Fifty-nine genera have 5 or fewer species,totaling 119 species,accounting for 8.58%of the total number of wild Lamiaceae species in China.Thirty-three genera are represented by only one species in China,indicating a high genus diversity but low species richness within genera.The primary genera are Scutellaria,Salvia,and Isodon,with a total of 394 species,accounting for 28.62%of the total species.Wild Lamiaceae are distributed across all provinces,autonomous regions,and municipalities in China,primarily in the eastern Himalayas,the mountains of western Hubei and eastern Chongqing,southeastern Tibet-northwestern Yunnan,and the mountains of eastern Yunnan-western Guangxi.The highest species richness is found in Yunnan Province(658 species)and Sichuan Province(532 species).The flora of the genus was diverse.According to Wu Zhengyi's classification of the distribution areas of Chinese seed plant genera,the 100 genera of wild Lamiaceae in China belong to 15 typical types and 12 variant types.Tropical and temperate floristic elements dominate.Genera related to tropical flora account for 39 genera and 548 species,showing a significant predominance.Temperate elements follow,with six genera exhibiting a Mediterranean distribution and two genera exhibiting disjunct distributions between East Asia and North America.Wild Lamiaceae in China are functionally diverse,mainly categorized into medicinal plants,aromatic plants,nectar plants,wild vegetables,ornamental plants,and oil plants.Although some Lamiaceae groups have been explored for their value,many groups remain under-researched,warranting further mechanism research and utilization.
