摘　　要：以丽水市建设局村镇建设处提供的国家级传统村落申报材料中的古树信息为主要依据,结合走访调查,探究丽水市国家级传统村落内的古树资源分布情况。通过数据分析、区系检索比对等手段对古树的树种组成、区系特征、树龄结构和空间分布等进行了研究。所调查的7223棵古树,隶属于28科49属61种;统计分析得出8大优势科、11大优势属和10大优势树种,其中榧与柳杉的数量均超过1000棵;科的分布以世界广布型、泛热带分布型、北温带和南温带间断分布型为主,属和树种的分布以东亚和北美间断分布型为主;古树的树龄呈金字塔型分布,一级古树占总数的9.86%,主要分布在龙泉市,二、三级古树分别占28.57%、61.57%,主要分布在松阳县。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.
