摘要: 对阿拉善荒漠地区开垦、轮牧、过牧、禁牧4种不同干扰条件下子午沙鼠(Meriones meridianus)的种群空间分布格局进行了研究。在2016年的4月、7月、10月采用铗日法调查了子午沙鼠种群数量,并采用最近邻体距离法对不同干扰条件下的子午沙鼠种群空间分布格局进行了分析。结果表明,子午沙鼠平均密度为0.53只/hm^2,禁牧区子午沙鼠种群密度相对最大,为0.60只/hm^2,开垦区相对最小,为0.39只/hm^2,轮牧区和过牧区居中,分别为0.55和0.56只/hm^2;子午沙鼠在开垦区、轮牧区、过牧区、禁牧区的各个季节表现均为集聚分布。

Abstract: In the present study, the population spatial distribution pattern of Meriones meridianus under varied interference conditions(reclamation region, rotational grazing region, over grazing region and banning grazing region) in Alxa desert area was assessed. In April, July and October 2016, the population size of Meriones meridianus was investigated by trap-day method, and the population spatial distribution pattern of Meriones meridianus under varied interference conditions was assessed by nearest neighbor analysis method. The results showed that the average density of Meriones meridianus was 0.53 per hm^2; the highest population density of Meriones meridianus was observed in banning grazing region(0.60 per hm^2) followed by over grazing region(0.56 per hm^2) and rotational grazing region(0.55 per hm^2), and the lowest density was observed in reclamation region(0.39 per hm^2); the Meriones meridianus population exhibited an aggregated distribution pattern in reclamation region, rotational grazing region, over grazing region and banning grazing region in all seasons.
