低效防护林改造对林地生物多样性变化的影响

Effect of Inefficient Protection Forest Regeneration on Variation of Biodiversity of Stand

通过对福建龙岗试验地低效防护林分改造试验,分析和比较了林地生物多样性变化。结果表明:对低效林实施改造措施能够快速恢复防护林的恶劣环境,为芒萁及其它乡土草种、灌木的快速侵入,并为其生长创造条件,使林分内形成多草种、多灌木、多乔木的植被群落,并为乌类、昆虫及野生动物的栖息、繁衍创造一定生境条件,逐步恢复生态公益林的生物多样性。

Through the experiment of inefficient protection forest regeneration on the Long, gang Test Plot in Fujian province, the variation of biodiversity of stand were an.alyzed and compared. The results showed that applying regeneration measures on the inefficient forest could restore bad environment of protection forest. It could accelerate the invasion and create condition for Dicranopteris pedata and other native grass species and brushes. The vegetation community with varieties of grass species and brushes and trees was formed in stand. It could create habitat condition for resting and multiply of bird and insect and wildlife, and could restore gradually the biodiversity of Ecological ＆ Public Welfare Forest.
