摘　　要：调查福建山地河流生态系统中游禽的分布和活动规律,采用红外相机技术对同域分布游禽的日活动节律进行研究.从21台有效红外相机点位上,共获得独立有效照片2 217张.结果发现,在福建山地河流中有鸳鸯、绿翅鸭、斑嘴鸭、小鸊鷉4种游禽,其中鸳鸯的日活动节律呈现单峰型,中午达到活动高峰,且存在明显的季节差异和两性差异;绿翅鸭和斑嘴鸭的活动节律表现为双峰型,上下午各有一个活跃峰值;小鸊鷉日活动节律为单峰型,活动高峰出现在下午.相比其他游禽,鸳鸯与斑嘴鸭和绿翅鸭的日活动模式差异显著,但与小鸊鷉无显著差异.We used infrared camera technology to investigate avifauna's distribution and daily activity patterns in the mountainous river ecosystems of Fujian,China.A total of 21 effective infrared cameras were deployed,yielding 2 217 independent effective photographs.The results showed that four natatores were identified in the river basins:Aix galericulata,Anas crecca,Anas zonorhyncha,and Tachybaptus ruficollis.The daily activity rhythm of A.galericulata exhibited an unimodal activity pattern with a noon peak,demonstrating significant seasonal and sexual differences.A.crecca and A.zonorhyncha displayed bimodal rhythms,with peaks in the morning and afternoon.And T.ruficollis displayed a unimodal pattern,with its activity peak in the afternoon.Compared to other avifauna,A.galericulata exhibited significant differences in daily activity patterns with A.crecca and A.zonorhyncha,but not with T.ruficollis.
