摘要
指出了林麝种群在2000年以前分布很多,近年来林麝数量已经明显减少。龙洞沟地区不仅是太白山最主要的林麝分布区域,也是秦岭地区林麝最主要的分布区域。根据龙洞沟地区林麝的活动特点设计了调查样线,从海拔1600~2800m,每300m的海拔段设为一个调查样带,在每个样带内调查此区域野生动物种类、林麝活动情况和威胁林麝生存的因素。结果发现:林麝主要集中分布在龙洞沟海拔1900~2500m的落叶阔叶与常绿针叶混交林带,但此区域人为干扰很强烈,包括旅游、挖药和放套捕猎等行为。针对这一情况提出了相应的建议,以供参考。
The population of mosehus berezovskii was widely distributed before 2000, and the number had decreased in recent years. The Longdong Gully area was the main distribution area of moschus berezovskiiinTaibai Mountain, which was also the most important distribution area of moschus berezovskiiin Qinling area. In this paper,the investigation sample line formoschus berezovskii in Longdong Gully area was designedaccording to their activity characteristics. Elevation section of every 300mwas set up as an investigation belt between 1600-2800m elevation. The wild ani- mal species, activity situation of moschus berezovskii and threatening factors tosurvival of moscbus berezovskiiwere studied in every elevation belt. The results showed that the moschus berezovskii mainly distributed in the mixed deciduous broadleaf and evergreen coniferous forest zone of 1900-2500m elevationin Longdong Gully. The environment of moschus berezovskiihad brought great destruction and the range of activity of moschus berezovskii had been decrea- sing,due to human disturbance such as tourism, digging and nesting in this region. Hencethis paper presented some suggestions for this situation.
