摘　　要：2012年4月至12月,采用样线法和样点法对岐山县南北两山的鸟类资源进行了调查,结果显示:岐山县南北两山共计鸟类71种,隶属于11目22科,鸟类种数占陕西省鸟类种数的15.27%,其中,北山有鸟类9目18科35种,南山观察到鸟类9目16科48种.在这些鸟类中,有国家Ⅰ级重点保护鸟类1种,国家Ⅱ级重点保护鸟类12种;中国特有鸟类6种;列为IUCN近危的物种3种;列入CITES附录Ⅱ的物种12种.按区系成分划分,广布种有62种,东洋界9种.按居留型划分,有留鸟52种,夏候鸟15种,冬候鸟3种,旅鸟1种.在此基础上,分析了岐山县南北两山鸟类资源的区系特征及分布型;并采用G-F指数法进行了多样性测度评估,结果表明北山G-F指数明显大于南山G-F指数;提出了针对性的保护对策.In order to learn about the avian diversity on southern and northern mountains in Qishan County, a survey has been done by the line transect method and the point count method from April to December in 2012. The consequence of the survey shows： There are 71 avian species on both mountains, belonging to 11 orders and 22 families, the number of avian species is 15.27% of the total avian species in Shaanxi Province, there are 9 orders, 18 families and 35 species on northern mountain, there are 9 orders, 16 families and 48 species on southern mountain. Of the total avian species abserved, 1 avian specie belongs to national protected rank one animals and there are 12 avian specie belonging to national protected rank two animals. 6 speices are endemic to China, 3 speices near threatened are listed in IUCN, 12 speices are listed in CITES II. By floristic element, there are 62 cosmopolitan species and 9 oriental realm species. By residence type, there are 52 resident birds, 15 summer migrant birds, 3 winter migrant birds and 1 passing birds. We analyze the fauna characteristic and the type of distribution, regarding G-F index as a measure to analyze bird species diversity. The result shows that the G-F index of Beishan is significantly greater than in Nanshan＇s and finally some relevant protection strategies are put forward.
