【摘要】 采用半结构访谈法、样线法和红外相机技术相结合的研究方法,对西双版纳国家级自然保护区内的灰孔雀雉进行调查研究,结果表明,西双版纳国家级自然保护区除曼稿子保护区外,勐养、勐仑、勐腊、尚勇4个子保护区均有灰孔雀雉分布,潜在分布面积约222 825hm~2。春季种群密度为0. 004 60只/hm~2,种群数量为1 009只,冬季种群密度为0. 003 76只/hm~2,种群数量为858只,全年平均种群密度0. 004 18只/hm~2,种群数量平均值为931只,按照±5%的误差率来估算,西双版纳国家级自然保护区灰孔雀雉种群数量理论值为884-978只。灰孔雀雉对亚热带常绿阔叶林、热带雨林、热带季雨林3种生境有选择偏好,分布在海拔624-1 750m的区域。针对灰孔雀雉种群保护现状,提出了相应的保护措施。更多还原

【Abstract】 Using a combination of semi-structured interviewing,line-sequencing,and infrared camera technology,a investigation of Polyplectron bicalcaratum in Xishuangbanna National Nature Reserve was conducted. The results showed that in addition to the Mangao sub-protective area in Xishuangbanna National Nature Reserve,Polyplectron bicalcaratum also distributed in other four sub-protective areas of Mengyang,Menglun,Mengla,and Shangyong,with a potential distribution area of approximately 222 825 hm~2. We calculated that the spring population density was 0. 004 60 individuals per hm~2,the population was 1 009,individuals,and the winter population density was0. 003 76 individuals/hm~2,with 858 populations. The average annual population density was 0. 004 18 per hm~2,and the average number of population was 931. According to the error rate of 5%,the theoretical value of Polyplectron bicalcaratum’s population in Xishuangbanna National Nature Reserve was 884-978 individuals. Polyplectron bicalcaratum has selective preference for three habitats,namely subtropical evergreen broad-leaved forest,tropical rain forest,and tropical monsoon forest,and is distributed at altitude of 624-1 750 m. According to the status quo of Polyplectron bicalcaratum’s population,relevant conservation measures were proposed.更多还原
