摘要
2009年5月-2010年11月,通过对不同人为干扰程度马尾松林分节肢动物多样性进行调查和分析。结果表明,随着干扰的加剧,群落的物种数量、多样性和均匀度降低,而优势集中性增加;捕食性和植食性功能团个体数量增加明显,中性功能团则显著降低。重度干扰条件下,标准地存在主要害虫间歇性成灾,表明在人为活动干扰下马尾松林分抗虫能力减弱,群落多样性降低,增加了害虫侵入并成灾的风险,直接威胁到了马尾松林分的健康可持续发展的能力。因此应尽量减少人为活动对森林生态系统的影响,封山育林,营造松阔混交林,在保持森林生态系统安全稳定的前提下获得森林景观效益。
Through the investigation and analysis on the diversity of arthropods in different interference conditions of masson pine stands from May 2009 to November 10 2010,the results showed that the frequent interference by human beings reduced the species populations,diversity and evenness of the arthropod community in masson pine stands,but its advantage concentration increased.As the interference aggravated,the predatory and plant-predatory functional group were increased,while the others obviously decreased.There are intermittent plagues of the main pest in the severe interference,it could be included that the human interference affects the ability of its healthy and sustainable development.Therefore it should be widely promoted to reduce the impact of human activities on the forest ecosystem,and it is proposed to close the hillsides to facilitate afforestation and build pine and broad-leaved mixed forests.Under the guarantee of keeping the forest ecological system safety and stability,the forest landscape benefit was obtained.
