Abstract：Based on the information on ancient trees provided in the application materials for national-level traditional villages by the Village and Township Construction Office of the Lishui Municipal Construction Bureau,combined with field investigations,this study explores the distribution of ancient tree resources within the national-level traditional villages of Lishui.Through data analysis and floristic comparison methods,the study examines the species composition,floristic characteristics,age structure,and spatial distribution of ancient trees.Among the 7,223 ancient trees surveyed,they are classified into 28 families,49 genera,and 61 species.Statistical analysis identifies eight dominant families,eleven dominant genera,and ten dominant species,with Torreya grandis and Cryptomeria japonica each numbering over 1,000 individuals.The family-level distribution is primarily characterized by cosmopolitan,pantropical,and disjunct temperate-tropical patterns,while the genera and species are predominantly distributed in the East Asian-North American disjunction.The age structure of ancient trees exhibits a pyramidal distribution:first-grade ancient trees account for 9.86％of the total,primarily located in Longquan City,while second-grade and third-grade ancient trees account for 28.57％and 61.57％,respectively,with the majority concentrated in Songyang County.
