摘　　要：2003年和2004年冬季,采用粪堆计数法对陕西省凤县紫柏山自然保护区林麝Moschus berezovskii的种群密度进行了调查。结果表明,紫柏山自然保护区林麝总密度为(0.48±0.75)头.km-2(平均密度±标准差)。以针阔混交林的林麝种群密度最高,为(0.94±0.05)头.km-2(平均密度±标准误),阔叶林和灌木林次之,分别为(0.28±0.02)和(0.13±0.02)头.km-2(平均密度±标准误),草地(包括荒地)以及山顶草地+灌木+低矮乔木镶嵌景观中林麝密度均为0。在北坡,林麝主要分布在中山地带(海拔为1 700-2 100 m),南坡则主要分布在高山地带(海拔2 100-2 450 m),这种分布的差异可能与坡向和人为干扰有关。总之,紫柏山自然保护区林麝密度极低,迫切需要加强保护,恢复种群。During November and December in both 2003 and 2004, in Zibaishan Nature Reserve of Feng County,Shaanxi, China, the population density of Moschus berezovskii （forest musk deer） was surveyed using the pellet group count method. In this reserve the total population density of M. berezovskii was estimated at 0.48 ±0.75 individuals·km^- 2 （ mean ± SD）. The population density [ in individuals·km^- 2 （ mean ± SE） ] of forest musk deer in a conifer broadleaf mixed-forest was 0.94 ± 0.05, whereas in a broadleaf forest it was 0.28 ±0.02, and in shrubs it was 0. 13 ±0.02 （mean ± SE）. No pellets were found in grass plots （including abandoned tilled land） or nested landscapes with low trees, shrubs, and grass on mountaintops. On the north slope of this reserve, M. berezovskii were mainly distributed in the forest between 1 700 and 2 100 m elevation. However, on the south slope, the relatively high population density occurred in woodlands between 2 100 and 2 450 m. Slope exposure and anthropogenic disturbance mostly explained the distribution differences. Because of the extremely low density, urgent action is needed to count the forest musk deer so as to protect and restore the population.
