Abstract: Objective To study the distribution pattern of rodents in Qinghai province, China.Methods The data on 45species 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.
