Investigation and Utilization Analysis of Wild Forest Germplasm Resources in Jiexi County
摘要
Abstract
In order to investigate status and distributions of wild forest germplasm resources in Jiexi county and explore utilization values of tree resources,species composition,floristic geographic elements and resource utili-zation types of wild forest germplasm resources in Jiexi county were analyzed through line-transect and quadrat surveys,as well as literature review.Results showed that there were 434 species of wild forest germplasm re-sources in Jiexi county,belonging to 84 families and 237 genera,including 14 species of gymnosperms belong-ing to 5 families and 10 genera and 420 species of angiosperms belonging to 79 families and 227 genera.Depau-perate and mono families dominated at family level,while depauperate and mono genera dominated at genus level.Arbors(212 species)and shrubs(150 species)were dominant life forms.There were 46 families and 178 genera of tropical geographic components,accounting for 79.31%and 76.72%of total families and genera(ex-cluding cosmopolitan)of wild forest germplasm resources respectively.Tropical component was dominant,indi-cating tropical to subtropical characteristics.Based on resource utilization types,wild forest germplasm resouc-es could be classified into six types,including medicinal(259 species),ornamental(131 species),timber(107 species),edible(64 species),industrial raw materials(120 species)and key protected species(11 species).Among these,229 species had two or more resource utilization types.Wild forest germplasm resources in Jiexi county were rich in diversity and showed promising prospects for utilization in medicinal,ornamental and tim-ber fields.Some developed tree species were in excellent conditions,with rational and scientific development strategies.It was recommended to ensure conservation and development of forest resources on basis of maintain-ing ecological stability.关键词
