摘  要:
针对桥山林区天然林保护工程实施以来,林分密度增大,林分结构不合理等问题,在栎林生长与经营现状调查基础上,以近自然健康经营理论为指导,以目标树经营为基本经营模式,分别对栎类近成熟林、中龄林、幼龄林和松栎混交林等4种林地,采取不同的近自然经营技术,结果显示近自然经营2年后,林内乔木密度平均降低34.10%,林下幼苗密度栎林降低1.77%~5.59%,松栎混交林增加10.74%,灌草层盖度平均提高23.39%,枯落物厚度和覆盖率分别增加9.98%和11.33%,林地光照条件改善,林分质量提高;近自然经营技术可应用于桥山及自然环境相近林区栎林及松栎混交林经营管理。

摘  要:
In order to improve the oak forest in Qiaoshan,different thinning measures were taken in about 667 hm~2 of four different oak forests:near-mature oak forest,immature timber oak forest,young growth oak forest and pine-oak mixed forest,guided by close-to-nature forestry management theory.The result showed that after two years management,the density of arbor trees on average declined about 34.1%,saplings density declined from 1.77%to 5.59%.Oak-pine mixed forest increased by 10.74%,shrub and grass coverage increased 23.39% on average,the thickness and coverage of litters increased respectively 9.98% and 11.33%.Light condition has been improved and quality of stands increased also.
