摘  要:【目的】了解梵净山国家级自然保护区雉类的繁殖期栖息地选择及其空间分布,为保护区珍稀雉类的有效管理提供科学依据。【方法】于2017—2019年的雉类繁殖期的4—7月,利用60台红外相机,在梵净山国家级自然保护区选取了3个样区,每个样区布设20台,并基于占域模型研究了4种主要雉类的栖息地选择模式。【结果】1)红外相机共获得独立有效照片882张,记录到白颈长尾雉、灰胸竹鸡、红腹角雉、红腹锦鸡等7种雉类。2)占域模型结果显示,海拔是影响4种主要雉类的占用率的主要因素,白颈长尾雉、灰胸竹鸡和红腹锦鸡3种雉类的占用率与海拔呈明显负相关,而红腹角雉的占用率与海拔呈明显正相关,呈现不同的海拔分布格局。其中,灰胸竹鸡主要栖息于海拔1100 m以下,白颈长尾雉主要栖息于1500 m以下,红腹锦鸡适应不同的海拔,红腹角雉主要栖息于1500 m以上。3)4种主要雉类表现出2种相异的植被类型选择模式,灰胸竹鸡和红腹锦鸡,明显倾向于选择针阔混交林栖息,并明显不倾向选择常绿落叶阔叶混交林;而白颈长尾雉和红腹角雉倾向于在常绿落叶阔叶混交林栖息,并明显不倾向选择针阔混交林。在坡度的选择上,白颈长尾雉和红腹角雉选择相似,与坡度表现明显的正相关;而灰胸竹鸡和红腹锦鸡表现较弱的负相关。【结论】本研究在梵净山保护区利用占域模型探讨了4种主要雉类在繁殖期的栖息地选择及其空间分布差异,初步揭示了在梵净山保护区同域共存的模式。【Objective】The purpose of this work is to understand the habitats selection and spatial distribution of main pheasant species in Fanjingshan National Nature Reserve during breeding period and provide scientific basis for effective management of rare pheasants.【Method】From April to July during the breeding season of pheasants from 2017 to 2019,60 camera traps were set up in 3 sample regions(20 cameras in each sample region)to monitor the pheasants living in the area.The habitats selection patterns of four species of pheasants were studied based on occupancy modelling.【Result】1)A total of 882 independent valid photos were obtained by infrared camera.Seven species of pheasants were recorded,including Syrmaticus ellioti,Bambusicola thoracicus,Tragopan temminckii,Chrysolophus pictus,and etc.2)The results of occupancy modelling showed that altitude was the major factor affecting the occupancy rate of the four main pheasants,and the pheasants had different altitudinal distribution patterns.The occupancy rate of Syrmaticus ellioti,Bambusicola thoracicus,and Chrysolophus pictus were negatively correlated with the altitude(Bambusicola thoracicus mainly lived at altitude below 1100 m;Syrmaticus ellioti mainly lived at altitude below 1500 m;Chrysolophus pictus have adapted to life at different elevation).However,the occupancy rate of Tragopan temminckii,who actively lived at altitude above 1500 m,was positively correlated with the altitude.3)The four main species of pheasants showed two different patterns of vegetation type selection.Bambusicola thoracicus and Chrysolophus pictus were obviously inclined to choose coniferous and broad-leaved mixed forest for habitat,and obviously not preferred to choose evergreen and deciduous broad-leaved mixed forest;while Syrmaticus ellioti and Tragopan temminckii were inclined to choose evergreen and deciduous broad-leaved mixed forest,and obviously not preferred to choose coniferous and broad-leaved mixed forest.Meanwhile,as for the selection of slope,Syrmaticus ellioti and T
