河南省啮齿动物地理分布的聚类研究

The Glires (Rodentia and Largomorpha) recorded in Henan province are 29 speices. Its fauna and geographical distribution has been studied by Lu Jiqi et al(1996). This paper gives a cluster analysis on geographical distribution about these Glires.The "yes" or "no" of distribution of the Glires in every zoo-geographical province were regarded as two component status(1 or 0). The relative coefficient was taken for the similar degree of Glires in every two zoo-geographical provinces. The cluster was taken by similar mean method. This paper discusses the characteristics of geographical distribution and the reasons of its formation, and gives a comparison among the cluster result and the geographical division of Glires in Henan province. It is clear that the Glires species was poor in plain and farming area, but the population of these rodent were enormous. The species diversity was more abundant in the forest mountains. Meanwhile, the mingle of Palearctic Realmspeices and Oriental realm speices were very notable in Henan province.
