摘要
2015年7—8月对科克森山国际狩猎场盘羊的种群数量及密度进行了调查,系统分析了近几年盘羊种群变化情况,结果显示种群数量为930~1020只,密度为1.07±0.02只/km^2。并对雪灾、天敌、家畜等盘羊的受胁因素进行了分析,发现雪灾是导致盘羊种群数量下降的重要因素。通过管理部门进行有针对性地管理,目前盘羊种群稳定,保护成效明显。
Population and density of Ovis ammon （0. ammon） in Kekesen Hunting Grounds were investigated from July to August in 2015. And the change on the population of O. ammon was systematically analyzed. Results showed that the population was 930-1020, and the density was 1.07±0.02 argali/km2. Analysis on threaten factors of O. ammon such as snow disaster, natural enemy, live- stock, etc. showed that snow disaster was the key factor leading to a decline of O. ammon population. Through the effective management by relevant administrative departments, population of O. aramon was stable, and the protection effects were obvious.
