The Investigation on Wild Germplasm Resources of Fagaceae in Guangze County

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.
