摘要: 1988~1995年,采用定点观察法和绝对计数与相对计数结合法对龙虎山猕猴种群生态作调查研究。1990年核心区有猕猴14群,500只左右,猴群密度1.6群/km2 ,种群密度55.6只/km2 。猴群大小平均33.8±23.1(n=6)只。—般每隔4~5年分群一次,猴群群体年均增长率14.8%,种群年均增长率为9.7%。猴群中成年猴性比为7.6±6.5(n=12),1~3岁组的性比为 0.74±0.61 (n=4),群内来成年猴比例为67.7±3.1% (n=12)。发情交配期最早11月12日,最晚次年1月20日,高峰期12月上旬,持续3个月。产仔期最早4月1日,最晚8月14日,高峰期5月上旬,持续时间4个半月.繁殖率45.5%~100%,平均75.4±13.2%(n=21).新生猴死亡率较低,新生猴性比(雌:雄)平均0.74±0.34(n=5).

Abstract: During 1988 ~ 1995 years,applied the methods of direct census combine with relative estimate,the investigation of Macaca Malatta population was dealt with at Longhushan Nature Reserve,Guangxi。In 1990,the total population was estimated about 500 individuals in 14 groups in the central area of the Reserve.The group and population density was 1.6gr/km2and 55.6 indivi/km2 respectively.The average group Size was 33±23.1 ( n= 6).The group fission once 4~5 years,the group and the population growth averaged out to 14.8%and 9.7% per year respectively.The sex ratio of the adults was 7.6±6.5 (n= 12),and that of 1~3 years old was 0.74±0.61 (n=4).The immature take up 67.7±3.1%(n= 12)in a group.The mating season begin at Nov.12.put on end to Jan.20,with peaking in the first ten day of Dec,and it last three months.The birth seas on started on April.1.ended on the Aug.14 with peaking in the first ten day of May,and it last four and half months. The fertility ranged from 45.5% to l00%,with an average of 75.4±l 3.2 (n=21).The newborn monkeys have low mortality,and sex ratio was 0.74±0.34(n=5).
