【摘要】 我们于1975年和1981年两次对梵净山的鱼类进行调查,共采获1千余号标本,计有4目7科14亚科35属48种和亚种,占贵州鱼类总种数的23.7％。其鱼类区系具有以下特点:4个目中,鲤形目的种类最多,有38种和亚种,占79.2％,7个科中,鲤科鱼类为最大的类群,有33种,占68.8％。梵净山鱼类区系的物种组成以鲤形目以及鲤科鱼类为主体,此特征与我国各水系的鱼类区系组成是基本一致的;鲤科鱼类的10个亚科中,鮈亚科(10种,占30.3％)和鲃亚科(8种,占24.2％)的种类最多,为该区鲤科鱼类的主体,是该区鱼类区系的特征之一;根据对鲤科鱼类的起源与分化的研究,将中国的鲤科鱼类分为三个地理类群的理论,在梵净山鱼类区系中,东亚类群种类最多,有22种,占66.7％,其次为南亚类群,有11种,占33.3％,高原类群缺如;该鱼类区系中,有少数种类具跨水系分布的现象,是由于河流袭夺引起的。更多还原

【Abstract】 Fanjinshan Mountain is situated in the juncture of Jiankou, Songtao and Yingjiang County, in the northeast part of Guizhou Province and located at 27°49′50″-28°1′30″ Nand 108°45′55″-108°48′30″E. It is a water shed between Wujiang and Yuanjiang River systems. Water resources in the area are rich. There are eight big rivers in the area, which are separately belonging to the Wujiang and Yuanjiang River systems. In 1975 and 1981, the survey on fish on Fanjinshan Mountain Carried out. Some over one thousand specimen were obtained, including 48 species and subspecies belonging to 4 orders, 7 families, 14 subfamilies and 35genera, or of 23.7% of fishes in Guizhou Province. The characteistics of the fish-fauna are as following: Ⅰ. The number of Cypriniformes is maximum. There are 38 species, of 79.2%. Among 7 families, Cyprinidae is the biggest one, altogether 33 species being collected,of 68.8%.The formation of fish-fauna in Fanjinshan Mountain, is similar to each river system in China, which take Cypriniformes and Cyprinidae as a principal part. Ⅱ. Among 10 subfamilies of Cyprinidae, Gobioninac (10 species, of 30.3%) and Barbinae (8 species, of 24.2%) are maximum in number. It is the characteristics of the principal part of Cyrinidae, and also one of the fish-fauna in the area. Ⅲ. According to the classification theory of Chinese Cyprinidae,which has three geographical types due to the origin and differentiation of Cyprinidae, the species of those of East Asia are maximum in number, 22 species, of 66.7%; those of South Asia being then second, 11 species, of 33.3% in the fish-fauna of Fanjinshan Mountain area. It is out of existence of those of Plateau. Ⅳ. In this fish-fauna, a few species have a appearance of being dispersed in different river systems because of the river running to another.更多还原
