摘要
2004年和2005年的4～7月，采用绝对数量调查与样线调查相结合的方法，分别对甘肃省东大山自然保护区和盐池湾自然保护区的高山雪鸡繁殖期种群密度进行了调查研究。结果表明，东大山核心区高山雪鸡繁殖期的种群密度为7．12±1．05只／km^2（5．85～8．33），总体密度为4．88±1．50只/km^2（3．33～6．32）；盐池湾高山雪鸡繁殖期的种群密度为4．25±2．10只/km^2（2．86～6．67）。东大山核心区高山雪鸡的种群密度与1990年相比稍有下降，而总体密度则有所上升。人工捕捉和偷猎等是影响研究区内高山雪鸡种群数量的主要因素。
The survey on the population density in breeding season of Himalayan snowcock Tetraogallus himalayensis was conducted with total number count and line-transect census methods in Dongdashan and Yanchiwan Nature Reserve, Gansu Province, from April to July, 2004 and 2005. The population density of the adult snowcock in the core areas of Dongdashan was 7.12 ±1.05 ind. / km^2 （5. 85 N 8.33）, and the total density was 4. 88 ± 1.50 ind./km^2 （3.33 N 6. 32）. The population density in breeding season in Yanchiwan was 4. 25 ± 2. 10 ind./krn2 （2. 86 -6. 67）. The population density in eore area of the Dongdashan reduced slightly, compared with that of 1990, but the average density was increased. Capture and illegal hunting were the main cause of the decline of their number.
