| 林木种质资源是林木良种选育的基础材料,也是林业生产发展的基础和核心资源。为充分保
护和有效利用林木种质资源,采用踏查、线路调查和样方调查等方式对剑阁县林木种质资源进行普查。结果表明,剑阁县林木种质资源共计85 科228 属423 种,被子植物76 科211 属394 种,裸子
植物9 科17 属29 种,生活型包括乔木(221 种)、灌木(158 种)、木质藤本(35 种)、竹类(9 种);收集到野生林木种质资源42 份,包括23 科28 属35 种,通过区系分析发现,该区域所分布的热带属
性野生植被占比较大,同时又包含一部分温带属性植被,收集到栽培利用的林木种质资源75 份,分属33 科50 属55 种,包括经济林类林木种质资源11 科16 属16 种,造林、绿化类林木种质资源25 科37 属40 种;散生古树名木58 株,属于12 科16 属18 种;古树群17 个,包括14 个古柏古树群、1 个黄
连木古树群、1 个岩栎古树群和1 个无患子古树群,古树名木共计10 754 株。全面掌握和分析了剑阁县林木种质资源现状,并结合当地实际提出林木种质资源保护及利用相关建议。 |

| Forest germplasm resources serve as the foundational material for superior tree breeding and
core resources for forestry production and development. To fully protect and effectively utilize these resources,
a comprehensive survey was conducted in Jiange County using methods such as reconnaissance,
line transect surveys, and quadrat sampling. The results showed that Jiange County hosts a total of 423
species of forest germplasm resources, belonging to 228 genera and 85 families. Among these, angiosperms account for 394 species from 211 genera and 76 families, while gymnosperms comprise 29 species
from 17 genera and 9 families. The life forms include trees (221 species), shrubs (158 species), woody
vines (35 species), and bamboos (9 species). A total of 42 wild forest germplasm resources were collected,
covering 35 species from 28 genera and 23 families. Floristic analysis revealed that the region has
a significant proportion of tropical wild vegetation while also containing temperate species. Additionally,
75 cultivable forest germplasm resources were collected, belonging to 55 species from 50 genera and 33
families, including 16 species from 16 genera and 11 families of economic forest resources, and 40 species
from 37 genera and 25 families of afforestation and greening resources. The survey also identified 58
scattered ancient and famous trees, belonging to 18 species from 16 genera and 12 families, as well as 17
ancient tree communities, comprising 14 ancient Cupressus
funebris tree clusters, 1 ancient Pistacia
chinensis tree cluster, 1 ancient Quercus acrodonta tree cluster, and 1 ancient Sapindus mukorossi tree
cluster, totaling 10 754 ancient and famous trees. This study comprehensively analyzed the current status
of forest germplasm resources in Jiange County and proposed recommendations for their protection and utilization
based on local conditions. |
