| 摘 要： | 2015年7—8月,利用预设样线法对科克森山国际盘羊狩猎场盘羊准噶尔亚种种群结构进行了调查。共计调查样线57条,总长度631.5km,记录到盘羊675只,其中雄性239只,雌性436只。盘羊密度为1.07±0.02只·km-2,雌雄比例为1.8∶1,初步估计该狩猎场的盘羊数量在930~1 020只。在确定年龄、性别的基础上,对盘羊的年龄分布和种群结构的合理性进行了分析,对利用直观观察结合照片研究盘羊种群结构的方法进行了探讨。

| Abstract: | From July to August in 201 5,Junggar subspecies population structure was investigated by using the de-fault sample line method in Kekesen mountain international Ovis ammon hunting grounds.Total 57 transect lines sampled,with 631.5 km,675 O.ammon recorded,including 239 males,436 females.O.ammon density was 1.07 ±0.02 per km2 ,male and female ratio was 1.8:1,the initial estimates the number of O.ammon hunting grounds was in 930-1 020.Based on determined age and sex,age distribution of O.ammon and the rationality of the population structure were analyzed,and the method to study O.ammon population structure was discussed combined visual observation with photo in this paper. |
