摘    要:2002年至2003年,对九寨沟自然保护区兽类进行了6次野外考察。调查确认,保护区有兽类78种,其中东洋界种类50种,古北界种类25种,广布种3种;有10种分布型。保护区兽类物种分布体现了较高的南北类群渗透性和残遗性;有20种国家Ⅰ、Ⅱ级保护动物,其中Ⅰ级6种,珍稀性较明显;有四川林跳鼠、四川毛尾睡鼠、沟牙田鼠等稀有小型种类;随着海拔增加,兽类分布呈现古北界种类增多,东洋界种类减少的趋势,但在海拔3200~3600m,古北界和东洋界种类都仍然丰富,仍然表现出区系的过渡性特征。

关 键 词:九寨沟自然保护区  兽类  区系

Abstract:From 2003 to 2004,the mammal fauna of the Jiuzhaigou National Nature Reserve was surveyed. Six separate surveys were conducted during this period. A summary of these collections showed that there are 78 species mammals in the Jiuzhaigou National Nature Reserve. An investigation of the biogeographic origin of this mammal fauna indicates that 50 species belong to the Oriental realm, 25 species belong to the Palaearctic realm, and 3 species are widely distributed. Ten general patterns of distribution were noted among the 78 species of mammal. This reserve's mammals show a very high south-north penetrability and antiquity.Twenty species in this reserve have been identified as nationally protected rare mammals; six of the species are first grade protected rare mammals. In addition, there are many rare small mammals in the reserve, such as the China jumping mouse(Eozapus setchuanus), Chinese Dormouse (Chaetocauda sichuanensis) and Bedford's vole (Proedromys bedfordi). There is a distinct trend for an increasing proportion of Palaearctic mammals and decreasing proportion of Oriental mammals as one ascends from 2 000 - 3 600 m . However, 3 200 - 3 600 m there is an abundance of both Palaearctic and Oriental species. These results show that this mammal fauna is broadly in transition in this area, including at elevations above 3 200 m.
