摘　　要：于2019年采用样线和标准地调查结合查阅相关文献的方法,对光泽县壳斗科(Fagaceae)植物野生种质资源进行调查,总结光泽县壳斗科野生种质资源数量、分布特点和植被类型。结果表明,光泽县壳斗科植物野生种质资源种类丰富,达5属30种,种数占福建省野生壳斗科植物(5属64种)属、种的100%、46.9%。其中,绝大多数为高大乔木,计26种,占86.7%;锥属种数最多,达11种;栗属种类最少,仅1种。调查到1738条记录,福建省地方重点保护珍贵树种黑叶锥(Castanopsis nigrescens)调查记录达78条。光泽县壳斗科种质资源多数种分布范围较广,可达全县,主要分布在海拔300—1000 m,一般为集群分布,形成森林群落。壳斗科物种是组成光泽县常绿阔叶林、常绿与落叶阔叶混交林的主要成分,是针阔叶混交林的重要组成部分。研究结果可为天然林保护工程、森林生态系统研究等提供参考。In 2019,the wild germplasm resources of Fagaceae in Guangze County were investigated by means of line transect and standard field survey combined with literature review.The quantity,distribution characteristics and vegetation types of wild germplasm resources of Fagaceae in Guangze County were summarized.The wild germplasm resources of Fagaceae in Guangze County were abundant,with 30 species of 5 genera,accounting for 100%genera and 46.9%species in Fujian Province(64 species of 5 genera).Among them,the vast majority were tall trees,26 species,accounting for 86.7%;Conus had the maximum number of species(11),and Castanea had the minimum number of species,only 1.A total of 1738 records were obtained,and 78 records were obtained from Castanopsis nigrescens,a rare tree species under special protection in the province.Most of the Fagaceae germplasm resources in Guangze County have a wide distribution range,which can reach the whole county,mainly distributed at an altitude of 300 to 1000 m,and generally distributed in clusters,forming forest communities.Fagaceae species are the main components of evergreen broad-leaved forest and mixed evergreen and deciduous broad-leaved forest in Guangze County,and are an important component of coniferous broad-leaved mixed forest.The results can provide reference for natural forest protection project and forest ecosystem research.
