摘要 运用三维空间中的家域模型及其计算分析方法,结合全球定位系统和电子计算机计算技术,讨论了西藏东南部地区马麝的家域形态、面积及其不同性别与季节的差异。马麝的家域近圆形,不同时间它们虽有沿海拔高度的垂直迁移现象,但整个活动中心变化不大。夏季时,马麝的家域面积较小,进入秋冬季节则显著增加;其中,无性别特异性的普遍增加与秋冬季节的食物减少有关,而不同性别的变化比例差异与繁殖活动相联系。 This paper is about the home range study of the Alpine musk deer (moschus sifanicus) in the southeast area of Tibet Autonomous Region. Based on the 3 Dimmensional home range model of outmost convex polygon and with the Global Positioning System (GPS), we have drawn out its home range shape, home range size and the home range dynamics between different months from July to November. The shape of the Alpine musk deer is near to a cycle. In different time, the distribute elevation are difference, but the centure of whole period is very little variance. In summer, the home range size is smaller than that in autumn. For different sex of animals, the home range dynamics are significant difference, the average home range size of male 1 (M 1) is 35 5 hm 2 at the non product season (Jul. to Sept.), and it was expanded to 47 17 hm 2 at the pre product season (Oct. to the early of Nov.), 32 9% increased; the home range size of male 2 (M 2) from 25 2 hm 2 to 41 71 hm 2, 63 4% increased; and the home range size of female (F) from 28 95 hm 2 to 40 76 hm 2, 40 8% increased. In autumn and the early winter, the home range increased are related to the decrease of food supplies, but the divisions of different sexes are related to the status of productivity.
