摘要
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10754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 10754 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.
