摘　　要：猫儿山是华南地区的最高峰,为了了解其鸟类随着海拔高度变化的规律,利用网捕法和样线法对猫儿山地区的鸟类组成及分布格局进行了研究。结果表明,猫儿山地区共有鸟类268种,隶属于16目51科,其中留鸟130种,夏候鸟51种,冬候鸟15种,旅鸟72种。依据不同海拔的典型植被类型把猫儿山地区分成7类生境,其中低海拔的农田生境鸟类多样性最丰富,有156种。随着海拔的升高,猫儿山鸟类种数逐渐减少,G-F指数也表现相似的规律。猫儿山鸟类在区系组成上主要以东洋界鸟类为主,在181种繁殖鸟中,东洋界鸟类有149种,古北界鸟类有15种,其余为广布种。随着海拔的升高,东洋界的鸟类所占的比例逐渐降低,而古北界的鸟类所占的比例逐渐升高。猫儿山鸟类组成的垂直分布格局的形成是多种因素共同作用的结果。A study of the bird composition and distribution patterns was conducted in Mao＇ ershan region, South China＇ s highest peak, Northeastern Guangxi. Total of 268 bird species representing 51 families and 16 orders were recorded, including 130 residents, 51 summer migrant, 15 winter migrant and 72 passing birds. Based on elevation and vegetation, 7 types of habitat were categorized in this study. The most richness of bird species （156） was occurred farmland in lowland 〈 300 m. The bird species decrease as the elevation increase, 76 species in artificial bamboo （Phyllostachys heterocycla） and fir （Cunninghamia lanceolata） forest at elevation 300 - 600 m, 68 and 64 species in evergreen broadleaf forest （600 - 1 200 m） and evergreen and deciduous broadleaved mixed forest （1 200 - 1 700 m） in mid-altitudinal belt, 50 in mixed forest of deciduous broadleaved and conifer tress （1 700 -2 000 m）, 65 species in high elevation region （ 〉 2 000 m）. G-F index decrease with the increase of altitude and reaches the minimum in the peak of mountain. Of 181 breeding birds, 149 Oriental birds, 15 Palearctic birds and 17 widely distributed birds, inhabit different altitudinal gradient. The proportion of Oriental birds decreases and Palearctic birds increases with altitude increase. The vertical
