Abstract:

Objective To study the distribution pattern of rodents in Qinghai province, China. Methods The data on 45 species of rodents, belonging to 9 families and 2 orders, were retrieved. The Ward's method was used for cluster analysis of rodents in each physical geographical unit of Qinghai. Results The rodents in Qinghai were clustered into two groups. The rodents from Qiangtang Plateau and Guoluo Yushu Plateau were clustered into a new group at a distance coefficient of 0.13, and the rodents from mountains north to Qinghai Lake, mountainous unit of Huangnan, Huangshui Valley, Qaidam Basin, and Qilian Mountains in Qinghai were clustered into a new group at a distance coefficient of 0.21. Conclusion The clustering results show interrelation between rodents and environment in different geographical units.

摘要:

目的 分析青海省啮齿类动物区系分布特点,初步探讨青海省啮齿类动物地理分布格局。方法 通过文献资料检索,共收集青海省啮齿类45种,隶属2目9科。将青海省各自然地理单元作为基本单元,采用Ward's方法对各基本单元进行聚类研究。结果 青海省啮齿类聚为两大类群,青海羌塘高原和果洛玉树高原在距离系数为0.13水平上首先聚合为一个新类群,在距离系数0.21的水平上青海湖北山地、黄南山地、湟水河谷、柴达木盆地和青海祁连山地的啮齿类聚为一个新类群。结论 聚类结果体现了各动物地理单元啮齿类与其地理环境相互渗透的现象。
