摘　　要：以秦巴林区森林的垂直分布带为依据,应用聚类分析法对秦巴林区不同地区啮齿动物分布情况进行分析。结果表明:中山桦木林带、亚高山针叶林带和高山灌丛草甸带聚为一类,说明在以上三个地理单元,啮齿动物种类和数量相似;而浅山农作区、低-中山栎林带聚为一类,说明它们的啮齿动物分布相似。将不同垂直带的平均海拔高度与其啮齿动物种数进行相关分析,表明海拔高度和啮齿动物种数之间呈负相关。Based on the vertical distribution of forests in Qinba mountain, the rodent＇s distribution in Qinba mountain was analyzed with a cluster analysis. The result showed that the middle mountain birch zone, hemi-high mountain coniferous zone and high mountain bosk-meadow zone were a group, the number and species of rodents were alike in the above geographical cells. The flat mountain crop zone and low-middle mountain quercine zone were a group. The relationship between the altitude and rodents species was analyzed, and the results indicated that the altitude was negatively correlated with the number of rodent species.
