摘要
安顺地区的河流在鱼类动物地理学上具有比较特殊的意义。自 1982到 2 0 0 0年对境内 6县 (市 ) 2 4个采集点进行系统考察 ,共获鱼类标本 3 12 5个 ,计 14 9种 ,分属 6目 2 0科 87属 ,其中有 15种为贵州省新记录。鱼类区系组成的特征集中表现为长江上游乌江水系和珠江上游红水河水系鱼类类群分布的边缘区和交替区 ,分水岭北坡和南坡在鱼类分布上的区域差异已反映出科和属的替代 ,鱼类区系在地理分布区划上应划归东洋区东亚南区的长江上游小区和南亚亚区的珠江上游小区。
Anshun Area is located at the middle of Guizhou Province, 105°15′E-106°31′E, 25°21′N-26°38′N. It has a special position in ichthyo geography for its special geographic characteristics and climate (lowest 4.2 ℃ , highest 23.7 ℃). Since 1982, 3 125 fish samples have been collected from 24 spots in 6 counties. All the samples belong to 149 species, 6 orders and 20 families. The characteristics of the ichthyofauna composition show that the substitute between orders or families has occurred in the distribution edge and the supersede area of the population as well as the south side and north side of the watershed area due to the difference in distribution area of fish population. The ichthyofauna of Anshun Area in geographic distribution division should be regionalized to the areas of upper reaches of the Changjiang River in south region of east Asia and the upper reaches of Zhujiang River in subregion of south Asia along the east Pacific Ocean.
