摘　　要：2012年5月至2013年2月间,对梅州市区建筑区、城区斑块林地、周边农田和周边林地等四个不同的鸟类栖息地的鸟类取食情况进行了调查研究.结果表明:(1)梅州市区的鸟类取食集团的总数整体上随着城市化程度的提高呈减少趋势.(2)梅州市区的鸟类取食集团的物种数在总体上随城市化程度的提高而呈减少趋势.(3)某些鸟类的取食集团会随栖息地的不同而发生改变.(4)不同的鸟类取食集团的分布与不同的栖息参数有显著的回归关系.(5)食物丰富度、灌木层密度等因素是影响鸟类取食集团分布的主要因子.Foraging guilds of birds in Meizhou across an urban gradient were conducted from May 2012 to February 2013, which includes different urbanization level habitats of building areas, woody patch areas, the surrounding farmland and surrounding mountain areas. The results indicated that： （ 1 ） the numbers of the foraging guilds of birds tend to go down as a whole with the increasing of urbanization; （2） The species numbers of the foraging guilds of birds also tend to go down as a whole with the increasing of urbanization; （3） Some foraging guilds would change with the different urbanization level habitats; （4） Different foraging guilds had significant correlation with different urbanization level habitats; （5） Shrub cover and food abundance were the main factors influenced the distribution of most foraging guilds.
