摘要
为了解天目山毛竹林蔓延对本地鸟类多样性的影响程度,在毛竹林与常绿阔叶林植被交界处设置3组对比实验样地,分组统计活动在2种不同植被中的鸟类种类与数量。结果表明:常绿阔叶林与毛竹林植被内的鸟类种类比为7∶1,个体数量比为6∶1左右。即毛竹林内的鸟类种类及数量大大低于常绿阔叶林,而这种差异性可能是鸟类食物链及森林空间结构的影响所致。由此可见,毛竹林的不断扩展将对本地鸟类多样性造成较大的负面影响,并从维护自然保护区生态安全的角度提出了自然保护区核心区彻底清除毛竹林和实验区间伐毛竹林等人工干预措施,以控制天目山自然保护区毛竹林的蔓延。
Three comparative sample plots were established at intersection of Phyllostachys heterocycla var.pubescens forest and evergreen broad-leaved forest to observe the influence of a fast spread of bamboo on bird diversity in Tianmu Mountain National Nature Reserve,Zhejiang province.Statistics collected from these plots showed that bird species in bamboo forest was one-seventh of that in evergreen broadleaved one,and number of birds was one-sixth of that in evergreen broadleaved one.The difference might be a result of changes in food chain and spatial pattern of the forest.The results showed that a continuing spread of bamboo forest could have negative impact on bird diversity of the reserve.Propositions were offered to control the spreading of bamboo such as removing bamboos from the core of the Nature Reserve and thinning bamboos in experimental areas for maintaining ecological security of Tianmu Mountain.
