摘　　要：2019年10月—2021年5月,在云岭山脉南部地区采用红外相机法和样线法对小熊猫(Ailurus fulgens)的分布和活动节律进行研究,共收集到29个分布位点和94张小熊猫独立有效照片。小熊猫分布于大理市、漾濞县、剑川县、兰坪县和玉龙县,海拔3000~4000 m为优势分布区,林下有竹的常绿阔叶林、常绿和落叶阔叶林为优势分布生境。小熊猫全年的日活动节律呈现单峰型,高峰为01:00—03:00,低谷为18:00—20:00,四季对比发现冬季的活动强度比春、夏、秋季高,日活动节律在雨季、旱季无显著差异(Δ=0.83,P=0.64)。From October 2019 to May 2021,a preliminary study on the distribution and activity rhythms of red pandas(Ailurus fulgens)was conducted in the southern part of the Yunling Moun-tains using the infrared camera trapping approach and the line transects.A total of 29 distribution sites and 94 independent valid photos of red pandas were collected.The results showed that red pandas were distributed in Dali City,Yangbi County,Jianchuan County,Lanping County and Yulong County,with 3,000-4,000 m elevation range as the dominant distribution areas and evergreen,evergreen broad-leaved forest with bamboo understory and evergreen and deciduous broad-leaved forest vegetation type with bamboo understory were their dominant distribution habitats.Daily activity rhythm of the red panda showed a unimodal pattern throughout the year,with peaks occurring from 01:00-03:00 am and lows occurring from 18:00-20:00 pm.Comparison of the four seasons revealed that the activity intensity was higher in winter than that in spring,summer and autumn,and the daily activity rhythm was not significantly different in the rainy and dry seasons(Δ=0.83,P=0.64).
