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。
Based on the rebuilding experiment of low-efficiency shelterbelt in Longgang, Fujian, the change of forestland biodiversity was analyzed and compared.
