河南省啮齿动物地理分布的聚类研究

路纪琪等[1 ]对河南省啮齿动物区系与区划进行了研究 ,把河南省已知的 32种啮齿动物区系划分为豫西北太行山地森林省、豫西黄土台地农作省、豫东豫北平原及南阳盆地农作省、豫西伏牛山地森林省、淮南冲积平原农作省和豫南桐柏 大别山地森林省共 6个动物地理省。因为毛耳飞鼠(Ｂｅｌｏｍｙｓ ｐｅａｒｓｏｎｉｉ )、中华鼢鼠(Ｍｙｏｓｐａｌａｘ ｆｏｎｔａｎｅｒｉ)、针毛鼠 (Ｒａｔｔｕｓｆｕｌｖｅｓｃｅｎｓ) 3种动物尚无标本考证 ,故本文所列河南省啮齿动物计 2 9种。另据马勇等[2 ]研究 ,认为应恢复绒鼠平属 (Ｃａｒｙｏｍｙｓ)的分…

Cluster Analysis on the Gographical Distribution of Glires in Henan Province

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.
