摘　　要：20 0 0年 3～ 8月采用无线电遥测技术对董寨国家级自然保护区的白冠长尾雉 (Syrmaticusreevesii)繁殖期占区雄鸟的活动区进行了研究。对遥测时间超过 6 0天的 7只个体的研究表明 ,繁殖期白冠长尾雉占区雄鸟对活动区具有较强的依恋性 ;90 %调和平均转换法 ( 90 %HMT)计算的繁殖期活动区大小为 46 0± 13 7hm2 (n=7) ;繁殖初期、中期和末期的活动区大小分别为 2 4 5± 6 3、 19 6± 7 5和 17 9± 6 2hm2 (n =7) ;随着繁殖期的结束活动区与日活动区呈减小趋势。白冠长尾雉占区雄鸟对活动区的 3个亚区 (夜栖区、觅食休憩区和过渡区 )的利用时间存在明显差异 ,活动区所在地的植被结构的不同可能是造成这种差异的主要原因.The ranging behavior of territorial male Reeves’s pheasant(Syrmaticus reevesii) during the breeding season was studied between March and August 2000 in the Dongzhai National Nature Reserve(31°28′～32°09′N, 114°18′～114°30′E), Henan Province. We captured and radio-collared nine adult male pheasants during March and April, using snares set around a decoy male bird. The males were radio-tracked from late March to early August, but only data collected from the seven birds that were radio-tracked for over 60 days were used in the analysis. Radio-tagged pheasants were located two or three times each day by signal triangulation and their position recorded so that their home range size could be determined and their use of their home range assessed. Each individual was followed for three full-days each month and their locations recorded every 10 minutes so that detailed time budgets could be obtained. During the whole breeding season the home range size of radio-tagged males, determined using 90% harmonic mean transformation, averaged 46.0±13.7 hm\+2. Within this period, home ranges in the early breeding, mid-breeding, and late breeding periods were similar, averaging 24.5±6.3, 19.6±7.5 and 17.9±6.2 hm\+2 respectively. The larger average home ranges in the early breeding period were probably due to males seeking females for mating. The home range use of each radio-tagged bird was analyzed to determine which areas were used for the main activities recorded during the study: roosting, foraging and resting. As different areas were used for these activities, the time spent moving between these areas was recorded as being “in transition”. The roosting habitat had a relatively high proportion of old evergreen conifer trees and was used mainly at night. Most of the foraging and resting sites were in mixed conifer and broadleaf forest that was dominated by oaks. The radio-tagged male Reeves’s pheasant spent about 60% of the day in this habitat, possibly because its leaf foliage litter and sparse u
