大熊猫、羚牛和川金丝猴的生境利用比较

为了解同域分布的大熊猫(Ailuropoda melanoleuca)、羚牛(Budorcas taxicolor)和川金丝猴(Rhinopithecus roxellanae)的生境需求,采用野外调查方法,对小河沟保护区内大熊猫、羚牛和川金丝猴的生境利用进行了研究。结果显示:大熊猫、羚牛和川金丝猴在生境利用上既具有相似性,又具有差异性。与羚牛、川金丝猴相比较,大熊猫对环境有着更多的特殊生境需求。与环境样方(对照)相比较,大熊猫生境中的郁闭度和乔木密度都比较小,竹子盖度和竹子密度都比较大,距离灌木比较近;羚牛生境中的乔木密度比较小;川金丝猴生境中的灌木盖度比较大,距离灌木比较近。

Comparison of Habitat Use of Giant Panda,Takin and Sichuan Golden Monkey

To understand the habitat requirements of sympatric giant panda,takin and Sichuan golden monkey,we studied the habitat use of giant panda,takin and Sichuan golden monkey in Xiaohegou Nature Reserve by the field survey.Giant panda,takin and Sichuan golden monkey had both similarities and differences in habitat use.Giant panda had more special habitat requirements than takin and monkey.Compared with the environment,giant panda habitat was characterized by lower canopy and tree density,higher bamboo coverage and bamboo density,closer to shrub;takin habitat was characterized by lower tree density;and Sichuan golden monkey habitat was characterized by higher shrub coverage and closer to shrub.
