Based on the related published papers, and by using Geographic Information System (ArcGIS 9.3), this paper analyzed the species composition and geographical distribution of threatened fishes in Yunnan Province of Southwest China. There were 83 threatened species living in the Province, belonging to 5 orders, 13 families, and 47 genera. Cypriniformes was absolutely dominant, with 64 species, followed by Siluriformes, with 16 species. Cyprinidae fishes had 51 species, accounting for 79.7% of Cypriniformes. The most species of Cyprinid fishes were of Barbinae (14 species), Cyprininae (10 species), and Cultrinae (10 species). The threatened fishes could be divided into two zoogeographical regions, i. e., Tibetan Plateau region and Oriental region, and their species composition and geographical distribution were resulted from the historical evolution adapted to the related environments. Whatever in rivers and in lakes, the Cyprinid fishes were both absolutely dominant, occupying 36.1% and 31.3% of the total, respectively. The Cyprinid fishes in rivers were mostly of endangered species, while those in lakes were mostly of vulnerable species. The factors affecting the threatened fishes in the Province were discussed from the two aspects of geodynamic evolution and present situation.
基于相关已发表论文，并利用地理信息系统（ArcGIS 9.3），本文分析了中国西南部云南省受威胁鱼类的物种组成和地理分布。该省有83种受威胁物种，隶属于5目13科47属。鲤形目占绝对优势，有64种，其次是鲇形目，有16种。鲤科鱼类有51种，占鲤形目的79.7%。鲤科鱼类中种类最多的是鲃亚科（14种）、鲤亚科（10种）和野鲮亚科（10种）。受威胁鱼类可分为两个动物地理区域，即青藏高原区和东洋区，其物种组成和地理分布是历史演化适应相关环境的结果。无论在河流还是湖泊中，鲤科鱼类均占绝对优势，分别占总数的36.1%和31.3%。河流中的鲤科鱼类大多为濒危物种，而湖泊中的大多为易危物种。从地质动力演化和现状两个方面讨论了影响该省受威胁鱼类的因素。
