摘要: 采用最近邻体法、T 形取样法和负二项分布法对内蒙古达茂联合旗腾格淖尔地区的大沙鼠和子午沙鼠空间分布格局进行了研究。结果表明, 大沙鼠一年四季均为聚集分布, 子午沙鼠在冬春季为均匀分布, 在夏秋季为聚集分布。二种群间在冬春季为聚集或均匀分布, 在夏秋季为明显的聚集分布。对二者空间分布格局进行相关性检验, 冬春季二者为负相关, 夏秋季为正相关。

Abstract: The spatial patterns of the populations of Rhombomys opimus and Meriones meridianus in Tengenor area of Damaolianheqi Banner were studied during the period from October 1995 to October 1996. They were analyzed by means of the nearest individual, T-distance sampling and negative binomial distirbution. The results were shown that Rhom bomys opimusis in a state of collecting distribution around the all year but Meriones meridianus is of even distribution in summer. Collecting or even distribution is the states in winter but remarkably collecting distribution in summer between both populations shows negative relative in winter but positive one in summer.
