摘　　要：为了探究珍稀鸟类东方白鹳和白琵鹭在天津北大港湿地自然保护区内的迁徙停歇规律,2013年10月至2016年12月,采用观测计数方法,对2种鸟类在保护区内迁徙停歇期的起止日期、种群数量变化以及与日极值温度的关系进行初步研究.结果发现:东方白鹳春秋2个季迁徙季在北大港湿地的平均停留时间分别为(47.00±21.07)d和(51.00±5.94)d;白琵鹭春秋2个季迁徙季的平均停留时间分别为(156.33±8.14)d和(48.33±15.31)d.春季迁徙季东方白鹳离开时的最高和最低温度均显著低于白琵鹭离开时的数值;秋季迁徙季东方白鹳到达时的最高和最低温度均显著低于白琵鹭到达时的最高和最低温度.春季东方白鹳和白琵鹭大批迁来的日期随同期温度的升高而逐渐提前;秋季则随着同期温度的降低而逐渐提前.In order to investigate the migration regularity of two species of rare birds,Ciconia boyciana and Platalea leu-corodia,in Tianjin Beidagang Wetland Nature Reserve,observational counting methods were adopted for these two species of birds from October 2013 to December 2016. The arrival and departure dates of the stopover periods in the reserve,the population quantity and the relationship between population changes and the daily extreme temperatures were studied. It was found that：the average duration of the stopover periods of Ciconia boyciana during the spring and autumn migration were（47.00±21.07）d and（51.00±5.94）d respectively;the average duration of the stopover periods for Platalea leucoro-dia during the spring and autumn migration were（156.33 ±8.14） d and（48.33 ±15.31） d respectively. The average daily maximum temperature and minimum temperature in departure dates of Ciconia boyciana were significantly lower than those of Platalea leucorodia during spring migration,and the average daily maximum temperature and minimum temperature in arrival dates of Ciconia boyciana were significantly lower than those of Platalea leucorodia during autumn migration. In the spring,the arrival dates of the Ciconia boyciana and Platalea leucorodia at the stopover site were advanced with the temperature rise;in the autumn,they gradually advanced with the temperature reduction during the same period.
