摘要
本文以阿勒泰地区哈纳斯国家级自然保护区兽类为主，初步分析了其在调查区内各生态地理单元中的组成、分布特点和区系成份等。结果表明，该区哺乳动物种类甚多，有５０种。区系组成明显。区系特征上以耐湿性的北方种类（或泰加林种类）为主，占５２％；其它类型与北方类型在不同地段的渗透有明显差异。该区是国家级自然保护区，作为北方泰加林哺乳动物为主体的生存空间。
During August and September,from 1994 to 1996,we assessed the occurrence of medium and small-sized cats,ungulates and rodents in the Kanas National Natrue Reserve(KNNR),including southern parts of Altai Mountain.The aim of the research was to ascertain the status and the distribution types of the mammalian fauna of this region.The results are as follows: In an area of 5588 km 2,we recorded a total of 50 species from 6 different vertical belts situated between 800 and 3500m.Of these,34 species occurred in the pasture-grassland belt of the pre-southern foothill plain,35 species were found within the deciduous-coniferous mixed forest,32 species were encountered in the coniferous belt,16 species lived in the subalpine lawn belt,and 8 species and 3 species respectively,were distributed in the alpinelawn belt and high thunder belt. The mammalian fauna of KNNR belongs to the composition of the Northern type.The fauna is composed of 52% of the Northern type species,8% of the North-Western type species and the broad distributed species respectively 6% of the Middle Asian type and only 2% of the Highland type.The fauna of this mountain region is obvious of mixed origin as species of the Taiga Forest type and of the Middle Asian type (with particularly high densities) infiltrate into each other.This condition is typical for the forest belt.The number of the Northern type increases and Middle Asian type decreases with the rising elevation of the mountainous region.
