摘要
作者通过随机设置112个20m×20m的样方,采用Vanderloeg和Scaiva选择指数对四川片口自然保护区中华竹鼠生境选择进行了研究.结果表明,中华竹鼠喜欢选择东南坡、中坡位、坡度适中(25-45°)、上层乔木郁闭度大于50%的常绿落阔混交林或落叶阔叶林采食青川箭竹,对于基径较粗(大于10mm)、密度适中(20-40株/m2)、距水源较近且远离人为活动干扰的青川箭竹林更加青睐.
Adopting Vanderloeg and Scavia selection index by one hundred and twelve random samples,habitat selection of the bamboo rats in Piankou Natural Reserve was studied. The results are as follows:1、 Bamboo rats prefer to select the evergreen-deciduous and deciduous broadleaf forest.2、Bamboo rats show strong habitat preference for the moderate slope position and slope degree (25-45°) facing east and south with dense forest canopy (>50%) .3、 Bamboo rats prefer to select Fargesia rufa with moderate bamboo density (20-40clums/m^2)and thick basal diameter (>10mm) nearby water source.
