摘　　要：黑颈鹤(Grus nigricollis)为国家I级重点保护野生动物,其迁徙路线和动态始终是研究热点之一,对这一濒危物种的保护具有重要意义。四川省荥经县辖区是黑颈鹤迁徙所途经和停歇的重要区域之一,但长期以来缺乏系统的监测及针对性管理。本研究对2015—2017年间迁徙途经荥经县境内的黑颈鹤数量动态、迁徙路线和停歇地等进行了实地访查和定点监测,并对停歇地生境进行了评估。结果表明,黑颈鹤在春季向繁殖地迁徙大多途径荥经县西部的部分区域,而在秋季向越冬地迁徙时则倾向于选择东部区域。新庙乡和龙苍沟镇分别是春秋两季黑颈鹤在荥经境内的主要停歇范围,其对停歇地的选择受到食物资源、人为干扰、隐蔽条件等因素的影响。划定专门的保护小区,保留开阔的农地并在3月和11月迁徙期适当减少人为活动,是荥经县境内进行黑颈鹤保护的有效举措,有助于保证其顺利到达繁殖或越冬区。The black-necked crane(Grus nigricollis),listed as the National first-class key protected wild animals,has always been well documented in migration routes and dynamics,which is of significance to the protection of this endangered species.As one of the most important areas for migration of black-necked cranes,Yingjing county received less systematic monitoring and targeted management for a long time.In this study,the population dynamics,migration routes and stopover sites of black-necked cranes in Yingjing county from 2015 to 2017 were investigated and monitored,and the habitats of stopover sites were evaluated..The results indicated that most of the individuals tended to migrate through the western areas of Yingjing county in spring,while they tended to migrate back to their wintering area through the eastern areas of Yingjing county in autumn.Xinmiao and Longcanggou town,characterized by high vegetation cover and less anthropogenic disturbances,were considered as the representative stopover areas of the blacknecked cranes in Yingjing county in spring and autumn respectively.It is highly recommended to set up two mini nature reserves separately in the west and east of Yingjing county,and reduce human activities in March and November in stopover areas to ensure the natural migration pattern of black-necked cranes.
