Abstract: biotic environments coupled with confinement stressors can lead to psychological and physiological changes in captive golden snub-nosed monkeys (Rhinopithecus roxellana), such as stereotypic behaviors and elevated fecal cortisol levels. The Hangzhou Zoo environmental enrichment project involved seven individuals. Behavioral data were collected with an instantaneous sampling method between 08:30-10:30am and 14:00 -16:00 pm every working day from August 1st to November 1st, 2013. As a result of the enrichment, idle and stereotypic behaviors decreased significantly（P=0.021; P=0.034）while exploratory behaviors increased（P=0.018）. After environmental enrichment was provided, golden snub-nosed monkeys tended to climb, explore and look around more often than before enrichment（P=0.012; P=0.014; P=0.010）. An enzyme-linked immunoassay fecal cortisol analysis showed significantly decreased fecal cortisol levels in all but one male（P=0.028）. Altogether, behavioral and endocrine results showed that the welfare of golden snub-nosed monkeys was improved after enrichment.

摘要： 在笼养条件下，由于有限的空间和单调的笼舍结构，川金丝猴行为和生理指标发生变化，包括出现刻板行为和产生较高的粪便内应激激素。本论文旨在研究环境丰容对笼养川金丝猴日常行为以及粪便皮质醇水平的影响。于2013年8月1日至11月1日对杭州动物园内7只川金丝猴进行环境丰容后的行为观察。采用瞬时扫描法记录上午08:30-10:30和下午14:00-16：00的动物行为，并统计15种行为的发生频率。比较丰容前后每种行为的发生频率，结果表明环境丰容降低了川金丝猴的不活跃行为（P=0.021）和刻板行为（P=0.034），增加了其活跃行为频率（P=0.018）。环境丰容后，动物表现出更多的攀爬（P = 0.012）、探究（P = 0.014）和环顾行为（P = 0.010）。粪便皮质醇激素的结果表明，除1只雄性个体激素上升外，其余6只个体的粪便皮质醇含量显著下降（P=0.028）。以上结果提示环境丰容可改善川金丝猴的福利状况。
