摘 要 ：根据 1 997年 1月至 2 0 0 0年 1 2月的野外观察 ,对内伶仃岛猕猴种群年龄结构及发展趋势进行了研究。结果表明 :( 1 )内伶仃岛猕猴种群雌雄性比为 1∶ 0 .98,各年龄组性比幼年组为 1∶ 1 .0 7,青年组为 1∶ 0 .93,中壮年组为 1∶ 0 .6 ,中老年组为 1∶ 0 .5 7,老年组为 1∶ 1 .1 4 ;( 2 )列出了猕猴种群年龄结构图 ,确定了年增长率为 6 .9% ,种群数量的动态公式是 Nt=2 0 0 e0 .0 69t;( 3)预测了未来 1 0 a的猕猴种群的数量和发展 ,种群数量从 2 0 0 1年到 2 0 1 0年增长到 1 2 0 0头左右 ;( 4 )内伶仃岛猕猴种群发展的最适容纳量为 90 0～ 1 1 0 0头 (平均 1 0 0 0头 )。

Abstract:According to the observation in the field from January 1997 to December 2000,the age composition and dynamics of Macaca mulatta population in Neilingding Island were studied . The results showed that : (1) sex ratio (♀:♂) of Macaca mulatta population in Neilingding Island was 1∶ 0.98 , in which infancy group was 1∶1.07 , juvenescent group was 1∶0.93 , middle age group was 1∶0.6, middle-old age group was 1∶0.57 , old age group was 1∶1.14 ; (2) age composition pattern of Macaca mulatta population in Neilingdi...
