摘    要:2001年至2003年春季,采用样线调查和媒鸟招引,在河南董寨国家级自然保护区对我国特有珍稀雉类白冠长尾雉(Syrmaticus reevesii)的栖息地选择进行了调查,结合RS和GIS分析了在景观水平上对栖息地的选择性,并借助逐步逻辑斯谛回归分析了影响繁殖期白冠长尾雉栖息地的关键尺度和主要因素。结果表明,在白云保护站,占区雄性白冠长尾雉在不同栖息地类型中的出现频率不同,出现最多的是混交林,其次是杉木林,随后是松林、灌丛、阔叶林;在董寨自然保护区内,在115 m尺度和250 m尺度上,针叶林的面积比例均是影响其栖息地选择的关键因子,而到农田的距离是距离因素中最重要的因素。根据回归分析和AICC及ΔAICC值,115 m尺度上栖息地变量对白冠长尾雉繁殖期的栖息地选择影响最大。综合分析表明,影响白冠长尾雉繁殖期栖息地选择的主要因子为115 m尺度上针叶林的面积比例和到农田的距离。建议在制定白冠长尾雉栖息地保护策略时,应加强现有适宜栖息地的管理,改善栖息地布局,并从景观尺度上开展针叶林对白冠长尾雉种群影响方面的研究工作。

Abstract:Reeves's Pheasant (Syrmaticus reevesii) is a threatened pheasant species endemic to China.The habitat use of territorial male birds was surveyed by the help of live decoys in a core area of Dongzhai National Nature Reserve.The breeding habitat selection of this pheasant was examined at two scales (115 m and 250 m scale,i.e.4.15 hm2 and 19.63 hm2,respectively),including the characteristics at distance scale.Investigation was based on line transect,RS and GIS in Dongzhai National Natural Reserve from 2001 to 2003.Moreover,a range of habitat variables were compared between used and control points at each scale,and stepwise logistic regression was applied to select the key scale and the key habitat factors in relation to breeding habitat selection of this bird.Our results stated that the territorial males at Baiyun occurred mostly in mixed forests,followed by fir forests,pine forests,shrubs,and broadleaf forests.The area of conifer forests was the key factor influencing habitat selection of this bird in breeding period at the scales of 115 m and 250 m,and the proximity of farmland was important for habitat selection in breeding seasons.Furthermore,Reeves's Pheasants attached great importance to the scale of 115 m.When considering a range of habitat variables at all scales within a multivariate regression,the leading factors having effect on habitat selection in the breeding period were areas of conifer forests at 115 m scale and the distance to farmland.In addition,these above results suggested that strengthening the management of suitable habitat,and optimizing the habitat configuration are important in promoting conservation of this bird.However,it also highlighted the importance of initiating future researches on the conifer forests and their impact on the population of Reeves's Pheasants,which would be beneficial to promote the habitat conservation of this pheasant more effectively.
Keywords:Syrmaticus reevesii  Breeding period  Habitat selection
