摘  要:
2011年10月~2014年10月,为了了解花鼠种群与食物资源的关系,我们在凉水国家级自然保护区,采用样方法与标志重捕法对花鼠种群动态进行了研究,结果如下:2011年及2014年红松结实量呈爆发式增长,同期花鼠种群数量出现2个较高峰值;花鼠在2012年平均胎仔数达到最低值(1.04±0.13)只,同年越冬期生存率最低,达到(0.11±O.04);花鼠在2013年繁殖期后雌雄性比达到最高值1.17。数据分析表明,在研究期间,红松结实年际间波动明显。花鼠种群的波动基本与食物资源波动同步,在食物匮乏的年份繁殖力减弱,在食物充足的年份繁殖力提高。

摘  要:
Korean pine(Pinus koraiensis) is characterized by extreme fluctuation of annual seed production.We studied the relationships between this fluctuating food resource and Siberian chipmunks(Tamias sibiricus).We studied population dynamics of Siberian chipmunk by quadrat sampling and mark-recapture methods at Liangshui National Nature Reserve in Heilongjiang Province of China from October 2011 to October 2014.The chipmunk population reached two peaks in the mast years of 2011 and 2014.The mean litter size of chipmunk was lowest in 2012(1.04 +0.13) and wintering survival rate was only 0.11 ±0.04 in the same year.The ratio of females to males was 1.17;1 after the breeding season of 2013.Korean pine seed resources fluctuated strongly over the study period.The chipmunk population fluctuated in synchrony with food resources.Fecundity decreased in the year of food resource deficiency and increased in the year of seed abundance.
