| 水鸟的迁徙停歇是其生活史中极为重要的一个过程。迁徙停歇地的水文因子和人为活动的变化直接影响水鸟对迁徙停歇地的持续利用。本文统计了2015至2020年吉林长岭龙凤湖湿地省级自然保护区东方白鹳（Ciconia boyciana）迁徙季节的停歇种群数量和停歇期，并记录东方白鹳停歇地的水位和人为干扰类型，利用相关分析、差异性分析及一般线性模型等方法分析了生境因子对东方白鹳迁徙动态的影响。结果表明，东方白鹳在春季与秋季停歇期（Z = 17.500，P = 0.937）和停歇种群数量（Z = 0.890，P = 0.580）均无显著性差异；水域面积增加导致东方白鹳减少停歇期（F = 5.119，P = 0.038）；旅游干扰对东方白鹳停歇种群数量影响要明显大于车辆（Z =﹣2.783，P = 0.005）及放牧和摄影（Z = 1.679，P = 0.007）干扰。本研究结果提示，水鸟停歇地的管理者，需要合理调节水文变化，减少人类活动干扰，这对加强东方白鹳等珍稀濒危水鸟停歇地的管理和保护具有重要意义。 |

| [Objectives] Migration stopover is an important process in the life history of waterbirds. Changes in hydrology and anthropogenic factors directly affect the sustainable use of migration stopovers by waterbirds. [Methods] We counted the stopover number and duration during migration season of Oriental Stork (Ciconia boyciana) in Longfeng Lake Wetland Provincial Nature Reserve, Changling County, Jilin Province from 2015 to 2020, and recorded water level and human disturbance types, then analyzed the impacts of habitat factors on the migration dynamics of Oriental Stork by means of correlation analysis, differential analysis and general linear model. [Results] The results show that Longfeng Lake Wetland Provincial Nature Reserve is an important stopover site for Oriental Stork, the stopover duration (Z = 17.500, P = 0.937) and number (Z = 0.890, P = 0.580) in spring and autumn are basically same (Table 1); the increased water area resulted in the decrease of stopover duration of Oriental Stork (F = 5.119, P = 0.038); the effect of tourism activities on Oriental Stork’s stopover number was significantly greater than vehicle (Z =﹣2.783, P = 0.005) and photography (Z = 1.679, P = 0.007) disturbance, which indicated the former have more disturbance more than the latters for waterbirds. [Conclusion] This study suggest that the managers of waterbird stopovers adjust the hydrologic changes reasonably, reduce the interference of human activities, which is significant to strengthen the management and protection of endangered waterbirds such as Oriental Storks. |
