摘　　要：野生动物倾向回到或留在一个特定范围或者与原有区域完全重叠的行为被称为栖息地忠诚。利用GPS无线电颈圈对5只四川羚牛的家域及家域的季节和年度忠诚度进行了研究和分析(2006—2009年)。结果显示:四川羚牛年均家域面积为(MCP/FKE)(15.01±2.92)km2/(9.02±1.85)km2,但个体间及年际波动较大;季节间家域面积差异显著,个体家域的季节变化体现出较一致的变化模式,最大季节家域主要集中于春季和夏季。年际间季节家域忠诚度最高的是秋季和夏季,冬季家域年际忠诚度最低,春季家域忠诚度也相对较低。单因素方差分析显示季节间质心距离总体差异不显著,与家域重叠算法获得的忠诚度结论基本一致。Migrant and resident are observed to return or stay within a specific range of habitat,close to or completely overlap with its original distribution area,known as habitat fidelity. In this study,we estimated takin seasonal and annual home range size and its fidelity between years by utilizing 9 GPS radio collars on adult takin（2006—2009）. Results shown annual home range of takin was（ MCP / FKE）（15. 01 ± 2. 92） km^2/（9. 02 ± 1. 85） km^2,suggesting individual home range varied among individuals and years. For each individual,we found variation of seasonal home range between years. Most of individuals shown similar pattern of seasonal home range variation,thus the largest home range always found in summer or spring. We extracted the centriods of seasonal / annual home range polygon and calculate its distance between years. We tried the distance between two centriods as one surrogate of home range fidelity. Besides,we considered the overlap ratio of home range between two consecutive years as the most important parameter of home range fidelity. Therefore,we found annual home range fidelity of certain season variation exist,especially for summer and autumn. Both ways of home range fidelity assessment produced similar results.
