摘　　要：收集了卧龙国家级自然保护区2014—2019年红外相机调查中采集到的红腹角雉相关信息,使用物种分布模型(MaxEnt)预测红腹角雉在保护区内的适宜栖息地;采用核密度估计方法,分析了其在春夏秋冬四季活动节律差异。结果表明,在卧龙国家级自然保护区中,模型预测的红腹角雉潜在适宜栖息地面积为430.38 km^(2),占保护区总面积的21.52%,主要分布在保护区皮条河两侧中低海拔的针阔混交林中;在活动节律方面,红腹角雉在春季活动强度最高,秋季、夏季次之,冬季最低,红腹角雉在秋季的日活动节律与春季、夏季、冬季差异显著,而春季、夏季、冬季之间红腹角雉日活动节律无显著差异。本研究初步明确了红腹角雉在卧龙保护区内的潜在适宜栖息地分布以及春夏秋冬四季活动节律差异,为保护区红腹角雉乃至同域分布的其他雉类的保护与管理提供科学依据。In this study,the relevant information about Trgopan temminckii collected by infrared camera survey in Wolong National Nature Reserve from 2014 to 2019 was collected,and species distribution model(MaxEnt)was used to predict the suitable habitat of Trgopan temminckii in the Nature Reserve.The difference of activity rhythm in spring,summer,autumn and winter was analyzed using kernel density estimation method.The results showed that in Wolong National Nature Reserve,the predicted suitable habitat for Trgopan temminckii was 430.38 km^(2),accounting for 21.52%of the total area of the reserve,which was mainly distributed in the coniferous and broad-leaved mixed forest at middle and low altitude on both sides of Pitiao River in the reserve.In terms of activity rhythm,the highest activity intensity of Trgopan temminckii was in spring followed by autumn and summer,and the lowest in winter.The daily activity rhythm of Trgopan temminckii in autumn was significantly different from that in spring,summer and winter,but there was no significant difference between spring,summer and winter.This study preliminarily identified the potential suitable habitat distribution of Trgopan temminckii in Wolong National Nature Reserve and the difference of activity rhythm in spring,summer,autumn and winter,which provided scientific basis for the conservation and management of Trgopan temminckii and other Phasianidaes distributed in the same area in the reserve.
