海丰县野生林木种质资源研究

Research on Wild Forest Tree Germplasm Resources in Haifeng County

采用野外样线调查和文献查阅的方法对海丰县野生林木种质资源组成、区系特点、资源利用方式等进行研究。结果表明:海丰县共有野生林木种质资源238种,隶属于63科151属;乔木种类最多有123种,占总种数的51.68%;科级的主要组成部分是单种科,占总科数的41.27%;该地区野生林木种质资源区系以热带成分占据优势地位,呈现出明显的热带—亚热带属性;根据植物资源用途将海丰县野生林木种质资源划分为药用、观赏、用材、食用等13种类型,其中药用植物占优势地位,共有47科92属119种。结论:海丰县野生林木种质资源丰富,但部分植物生境人为干扰程度较严重,建议当地从实际情况出发,以保护为主,合理开发利用资源,深度挖掘木本植物资源利用价值,以促进海丰县野生林木种质资源可持续发展。

A field sample line survey and literature review were used to study the composition,zonal characteristics and resource utilization patterns of wild forest germplasm resources in Haifeng County.The results showed that there were 238 species of wild forest germplasm resources in Haifeng County,belonging to 63 families and 151 genera;the largest number of tree species was 123,accounting for 51.68%of the total number of species;the main component of the family level was the single species family,accounting for 41.27%of the total number of families;the wild forest germplasm resource system in the area was dominated by tropical components,showing obvious tropical-subtropical properties.The wild forest germplasm resources of Haifeng County were classified into 13 types of medicinal,ornamental,timber and edible plants according to the use of plant resources,among which medicinal plants dominate,with a total of 119 species in 92 genera and 47 families.Conclusion:The wild forest germplasm resources in Haifeng County are rich,but some of the plant habitats are seriously disturbed by human beings.It is suggested that the local authorities should take conservation as the main consideration,reasonably develop and utilize the resources,and deeply explore the value of using woody plant resources in order to promote the sustainable development of wild forest germplasm resources in Haifeng County.
