| 摘 要： | 武陵山区位于长江三峡南侧，是长江上中游支流的分水岭。区内分布有鱼类175种，其中特有种和稀有种分别有7种和6种，经济种50余种。文中结合地史演变和古生物资料对本区鱼类物种多样性的形成及其在动物地理区划中的地位作了讨论，认为沿武陵山脉存在一条动物地理区界线，该线南抵苗岭，北经鄂西山地伸达秦岭东麓。该线界分开了东洋区东亚亚区的华东小区和华西小区，即洞庭湖水系属于华东小区，清江和乌江应归为华西小区。

| Abstract: | Wulin Mountains region is situated on the border between Guizhou plateau and Dongting Lake plain, and is the watershed of the upper and middle reaches of Changjiang River. 175 species and subspecies of fishes have been recorded in Wulin Mountains, about occupying 17% of the total freshwater fishes in the China, belonging to 6 orders, 18 families and 83 genera. All of them are the endemic freshwater fishes of Asia, with exception of Anguilla japonica that is migration species. About 50 species have commercial value, of which 7 species are endemic species in the region and 6 species are endangered throughout China. In this paper, the process and the position of the ichthyofauna in the zoogeographic division were analyses. Considering the differences between east and west slopes of Wulin Mountains range as remarkable, a zoogeographical boundary line suggested was lied on the Wulin Mountains. The line divided the part of South east Asia Subregion into two areas. Namely, Dongting Lake plain is belonged to the East China, Qinjiang river and Wujiang river are situated in the West China. |
