摘　　要：为了解重庆金佛山国家级自然保护区林麝(Moschus berezovskii)对不同生境选择的偏好,于2022年7月—2023年8月,采用访问法、样线法、资料收集等方法对该保护区林麝生境中海拔、植被类型、郁闭度等9个生态因子进行实地调查。调查结果显示:1)林麝喜欢栖息于中高海拔区域、植被类型为针阔混交林和常绿阔叶林、郁闭度为中度郁闭、灌木盖度为低度覆盖、急险坡、距水源较近及远离人为干扰的具有岩石基底的生境。2)主成分分析表明,对金佛山保护区的林麝生境选择起重要作用的前3个主成分的累计贡献率达到73.351%,影响生境选择的主要因子依次是灌木盖度(0.915)、坡度(0.845)、距水源距离(0.833)、活动基底(0.812)、植被类型(0.759)和郁闭度(0.731)。上述研究结果为保护区管理人员对林麝展开有效保护和管理提供了科学指导和依据。In order to understand the preferences of Moschus berezovskii in different habitat choices in the Jinfo Mountain National Nature Reserve of Chongqing,a field survey was conducted from July 2022 to August 2023 using methods such as interview,sampling,and data collection to investigate 9 ecological factors such as altitude,vegetation type,and concealment in the M.berezovskii habitat of the reserve.The results show that:1)M.berezovskii prefer to inhabit habitats with rocky substrates in mid to high altitude areas,with vegetation types of mixed coniferous and broad-leaved forests and evergreen broad-leaved forests,moderate canopy closure,low shrub coverage,steep slopes,close to water sources,and away from human interference.2)Principal component analysis shows that the cumulative contribution rate of the first three principal components that play an important role in the habitat selection of M.berezovskii in Jinfo Mountain Nature Reserve reaches 73.351%.The main factors affecting their habitat selection are shrub coverage(0.915),slope(0.845),distance from water source(0.833),active substrate(0.812),vegetation type(0.759),and canopy closure(0.731).The above research results aim to provide scientific guidance and basis for the effective protection and management of M.berezovskii by protected area managers.
