| 摘 要： | 秦岭生态保护区地表径流众多,南北气候差异明显,因而孕育了种类丰富的野生鱼类。实地鱼类资源考察、检视鱼类标本以及参考鱼类分类、分布的文献表明,区内现有野生鱼类共7目16科75属141种（亚种）。通过物种多样性G-F指数的比较分析表明：区内鱼类的物种多样性在邻近省份中是最高的,而且该地区的鱼类区系地跨古北界和东洋界,具有显著的过渡区特点;区内不同水系间鱼类组成差异显著。目前,秦岭生态保护区野生鱼类的物种多样性正面临来自不合理捕捞、水工程建设、环境污染以及生态破坏等多方面的压力。为恢复和保护这一地区的野生鱼类的物种多样性,本文提出了有针对性的建议。

| Abstract: | Due to particular geography such as complex topographic form,temperate weather,abundant rainfall etc.,the diversity of wild fish species in the Ecological Protection Zone of Qinling Mountains was very high.A total of 141 species or subspecies,belonging to 75 generas,16 families and 7 orders,had been investigated by now.Compared with the adjacent Provinces,such as Sichuan,Gansu,Hubei and Henan,G-F index analysis of the species diversity showed that the Ecological Protection Zone of Qinling Mountains ranked t... |
