| 2010年到2013年，每年夏天，作者采用地图样带法对新疆木垒国际狩猎场天山盘羊(Ovis ammon karelini)的种群数量开展了调查，2010年和2011年调查区域面积为94.67 km2，2012年和2013年调查区域面积为72.97 km2。结果表明，2010年和2011年盘羊密度分别为(1.33±0.29)只/km2、(1.59±0.40) 只/km2由于狩猎活动干扰，2012和2013年盘羊密度显著下降，分别为(0.35±0.08) 只/km2、(029±0.17) 只/km2。在总计4次调查记录的83群319只个体中，大部分为雌性，说明这一区域是雌性天山盘羊主要的夏季栖息地。群体大小从1 ~ 17 只不等，平均群体大小为(3.84±0.35)只。食物资源的相对缺乏导致木垒国际狩猎场天山盘羊平均群体大小明显小于天山山区其他区域的种群，而相对较高的幼羊与雌羊比(45.5 : 100)说明木垒国际狩猎场适宜盘羊生存，为天山盘羊的理想生境。 |

| The information of Tianshan argali (Ovis ammon karelini) that distribute in eastern Tianshan Mts. has been rarely reported except Gao et al. (1997). In order to know the status of Tianshan argali since Gao’s report, from 2010 to 2013, we investigated the population of Tianshan argali in Mori International Hunting Ground of Mori County every summer by using the strip transect sampling method. The size of survey area is 94.67 km2 in 2010 and 2011, 72.97 km2 in 2012 and 2013. The results showed that, the densities of Tianshan argali in this hunting ground in 2010 and 2011 are 1.33?0.29 ind/km2 and 1.59?0.40 ind/km2 (Table 1). However, by using the non-parametric Mann-Whitney U test, the population density significantly decreased to 0.35?0.08 ind/km2 and 0.29?0.17 ind/km2 in 2012 and 2013 due to the continuous hunting for local museum. During the 4 times survey in summer from 2010 to 2013, totally 319 individuals in 83 groups were recorded, mostly are female groups (70 individuals in 31 groups) and Mother-offspring groups (106 female individuals and 80 lambs in 33 groups), only 11 male individuals in 10 groups, and 52 individuals in 9 groups are can’t recognized due to the long distance. This indicated that Mori International Hunting Ground was mainly inhabited by the female argali and their lambs. The group size of Tianshan argali Mori International Hunting Ground ranges from 1 to 17 (Fig. 1), with the mean group size is 3.84?0.35 individuals per group, which is significantly smaller than other parts of Tianshan Mountains due to relatively low level of food resources. And the relatively higher lamb to female ratio (45.5 : 100) indicated that Mori International Hunting Ground is the ideal habitat for Tianshan argali. |
