摘　　要：黄腹角雉时空分布及日活动节律仍不明确,不利于该物种有效保护。利用红外相机结合野外踏查收集明溪县境内黄腹角雉分布数据,探讨黄腹角雉潜在分布以及日活动节律。结果显示:明溪县黄腹角雉高适生区范围较小,面积仅14 km2,主要分布在明溪县北部;人为干扰因子对黄腹角雉潜在适宜生境分布影响较小,而降水量季节性变异系数和海拔是影响黄腹角雉空间分布主要环境变量,适宜生境降水量季节性变异系数范围为56.0%~58.5%,适宜生境海拔范围为830~1 561 m;野生黄腹角雉与人工投喂环境下黄腹角雉日活动节律重叠系数为0.623,但日活动节律差异显著(P<0.01),人为干扰对黄腹角雉日活动节律影响更为明显。研究结果可为黄腹角雉种群保护提供理论支持。The spatio-temporal distribution and diurnal activity rhythms of the Yellow-bellied Tragopan(Tragopan caboti)remain unclear,which has hindere the effective conservation efforts for this species.To ad-dress this issue,we combined infrared cameras with field surveys to gather data on the spatio-temporal distri-bution and diurnal activity patterns of Yellow-bellied Tragopans within Mingxi County,aiming to uncover their distribution areas and diurnal activity patterns.The results reveal that the highly suitable habitat for Yel-low-bellied Tragopans in Mingxi County is relatively small,covering an area of just 14 km2,primarily situat-ed in the northern part of the county.Human disturbance factors have a limited impact on the habitat distribu-tion of the Yellow-bellied Tragopan.However,the seasonal variation coefficient of precipitation and altitude are the primary environmental variables influencing their spatial distribution.The suitable habitat has a pre-cipitation seasonal variation coefficient ranging from 56.0%to 58.5%,and an altitude ranging from 830 to 1561 meters.The overlap coefficient of diurnal acyivity rhythm between wild and artificial feeding was 0.623,but the difference was sifnificant(P<0.01).The influence of human interference on diurnal activity rhythm was more obvious.The results can provide theoretical support for the population conservation of tragopan.
