摘　　要：为了摸清十堰市古树资源现状和特征,在收集资料基础上,对十堰市古树资源的优势树种、地理分布、分布区类型、株龄结构等进行分析。结果显示:十堰市古树共有7429株,隶属42科91属150种,主要以壳斗科、豆科、漆树科、胡桃科和樟科等14个科的槲栎、栓皮栎、黄连木、皂荚、枫杨和银杏等树种为主,古树资源分布类型丰富,呈现显著亚热带向温带过渡的特点,古树科的分布区类型以泛热带分布型为主,在数量上北温带及其亚型分布科所属的种占据绝对优势。树龄主要集中在100~399 a,平均株龄245.3 a。古树分布密度方面武当山风景区优势明显。同时针对本区域内古树资源分布区类型和树种特性,为资源开发利用提出建议。To ascertain the current status and characteristics of ancient tree resources in Shiyan City,the dominant species,geographical distribution,distribution type and age structure of ancient tree resources were analyzed based on the collected data.The results showed that there were 7429 ancient trees in Shiyan City,belonging to 42 families,91 genera and 150 species.The majority of these trees are species such as Quercus aliena,Quercus variabilis,Pistacia chinensis,Gleditsia sinensis,Pterocarya stenoptera,and Ginkgo biloba,which belong to 14 families including Fagaceae,Fabaceae,Anacardiaceae,Juglandaceae,and Lauraceae.,and the distribution types of ancient tree resources are rich and exhibit significant characteristics of a subtropical-to-temperate transition.The distribution patterns of ancient tree families are mainly pantropical,while species belonging to families distributed in the North Temperate Zone and its subtypes numerically dominate.The tree ages are concentrated mainly between 100 and 399 years,with an average age of 245.3 years.The Wudang Mountains scenic area has a significant advantage in terms of the density of ancient tree distribution.Based on the distribution types and species characteristics of ancient tree resources in this region,suggestions for resource development and utilization are proposed.
