中文摘要：

社会顺位等级制度在灵长类动物中普遍存在，它对动物个体的繁殖和社会行为有广泛的影响。本研究对黄山短尾猴鱼鳞坑YA2群6个不同顺位成年雄性个体，根据顺位高低，将它们分成3组：高顺位组（2只个体）、中等顺位组（2只个体）、低顺位组（2只个体），采用目标动物取样法对它们的社会行为进行研究，结果表明，3组之间（1）接收和发出架桥行为频次差异显著，高顺位组接收架桥次数最多；（2）接收和发出爬跨行为频次差异显著；低顺位组接收爬跨次数最多；（3）发出呈臀行为频次差异显著，但接收呈臀行为频次差异不显著；高顺位组是接收呈臀次数最多，低顺位组发出呈臀次数最多；（4）摇树行为频次差异显著，高顺位组发出摇树行为最多。因此雄性黄山短尾猴友好行为可以体现出社群顺位等级关系，这种社群顺位等级关系和这些友好行为在维持社群稳定上有重要作用。

英文摘要：

Dominance hierarchy which influences male reproductive behavior and social behavior, has often been reported in non-human primates. We examined aspects of dominance hierarchy in the Tibetan macaque （Macaca thibetana） at Mt. Huangshan, China. Six adult males were assigned into 3 groups ： the dominant group, medial group and subordinate group, respectively, as representing their dominance rank in the YA2 troop at Mr. Huangshan. Social behavior data were collected using focal animal sampling. Our results showed： （ 1 ） The dominant group participated most often in bridging behavior; the frequency of sending and receiving bridging behavior was significantly different among different ranks ; （ 2 ） The subordinate group participated most often in social mount behavior, the frequency of sending and receiving social mount behavior was significantly different among different ranks; （3） The dominant group received present behavior the most often, while the subordinate group was most likely to present. Frequency of sending present behavior also varied significantly among different ranks, but there was no significant difference in receiving present behavior among the different ranks; and （4） Frequency of shaking tree behavior was significantly different among the different ranks. We speculate that amicable behaviors reflect the social dominance rank and are an important way to sustain social stability.
