摘要
本文以统计生态学方法，分析宁夏啮齿动物分布上的种间关系。结果显示：有１１５个种对间的种间关联达显著以上水平，其中正、负关联分别为４５个和７０个，正负关联达极显著水平的种对分别为２１个和２３个，完全关联和完全负关联的种对分别为７个和５０个。对啮齿动物分布的聚类分析表明，宁夏啮齿动物的地理区划分为２个动物地理省、５个动物地理州。
The interspecific associations on the distribution of Clires in Ningxia Autonomous Region were studied by using the methods of statistics ecology. The results showed that there are significant interspecific association between 115 species pairs, in which, there are 45 positive associations and 70 negative associations. There are most significant positive associations in 21 species pairs and negative associations in 23 species pairs respectively (P<0. 01), positive and negative associations completely in 7 and 50 species pairs respectively.The results of cluster analysis showed that the region can be divided into two zoogeographical provinces and five zoogeographical states.
