中文摘要	【目的】确定库姆塔格沙漠野骆驼的活动范围和生境利用情况,识别野骆驼的迁移路径,为野骆驼的管理和保护提供对策。【方法】利用卫星追踪定位技术,于20 142016年在库姆塔格沙漠地区对3峰野骆驼进行追踪监测,利用最小凸多边形法计算野骆驼的活动范围,利用内核法分析野骆驼对生境利用的情况。【结果】 3峰野骆驼个体的家域面积分别为7 596.44、8 152.10、1 162.17 km~2;从季节来看,春季野骆驼平均活动范围最大,为902.79 km~2,冬季次之,秋季和夏季最小;总体来说,3峰野骆驼的生境利用有所重叠,但不同个体对生境利用的主要区域有所差别;不同季节野骆驼的生境利用也有所不同,夏季均在较为凉爽的阿尔金山北麓活动,冬季并不是所有个体会聚集在温暖的阿奇克谷地活动;春、秋2季野骆驼的活动热点分布在水源点附近。野骆驼最快能在30 h内完成1次跨越库姆塔格沙漠的迁移,其迁移多数是在发情繁殖期间,尤其是末期的4月。【结论】通过对野骆驼生境利用的分析,可初步确定不同季节野骆驼集中利用的区域和迁移路线,这将为野骆驼及其生境保护管理提供依据。但本研究数据量偏少,需要进一步开展系统研究,以期深入揭示野骆驼的生境需求和迁移活动规律。
英文摘要	【Objective】The aim of this study was to investigate the home range,habitat selection,and migration routes of the wild Bactrian camel (Camelus ferus) in the Kumtag Desert,China.【Method】Three wild camels in Kumtag Desert were outfitted with satellite tracking collars and monitored from 2014 to 2016. Minimum convex polygon (MCP) was used to calculate home range. Kernel model was used to analyse habitat selection.【Result】During the entirety of the study period,the 100% MCP home range of three wild camels reached 7 596.44 km~2,8 152.10 km~2,and 1 162.17 km~2, respectively. In terms of season,the home ranges were the largest in spring,followed by winter,and then autumn and summer. Different individual used separated core areas but exhibited some overlap with one another. Individual camels picked different habitats in different seasons. For example,while all three camels moved to the cooler Altun Mountains in summer,however they did not all move to the warm Aqike Valley in winter. Home range hotspots were centered around watering holes during spring and autumn. Most migrations occurred during the breeding season,peaking in April. The wild camels were able to complete a migration from north to south movement across the Kumtag desert within 30 hours. 【Conclusion】Based on the analysis of habitat utilization of wild camels,the areas and migration routes of wild camels in different seasons are preliminarily determined. The determination of key areas will provide a basis for the protection and management of wild camels and their habitats. Due to limited samples and data,further research is necessary to reveal the habitat selection and migration mechanism of the wild camel population in Kumtag Desert,China.
