摘　　要：对1997—2015年间半散放赛加羚羊的繁殖性能指标与当地气候因子进行了相关性和线性回归分析。结果表明:年最高气温、年最低气温对雌性赛加羚羊盛期发情率影响最大;年最高气温对幼羔成活率影响显著(P<0.05)。本研究说明赛加羚羊自引入后对中心所在地半荒漠区气候环境产生了一个适应过程。The present study was conducted to examine the correlation between local climatic factors and reproductive characteristics of Saiga tatarica from 1997 to 2015 years. The results showed that highest and lowest temperature had the greatest impact on peak estrus rates of female Saiga tatarica. The annual maximum temperature had significantly affected the survival rate of lambs （P〈0. 05）. This study suggested that Saiga antelope experienced a process of adaptation for the local climate environment of the semi desert since the introduction of the center.
