摘要
从2001年11月到2002年1月,沿城市化梯度对杭州城市的建筑区、城区斑块林地、西部山区等不同城市化栖息地的鸟类取食集团进行了研究.结果表明:(1)随着城市化程度的提高,鸟类取食集团的总数量在整体上呈减少趋势;(2)随着城市化程度的提高,鸟类取食集团的物种数在整体上呈减少趋势;(3)鸟类取食集团的结构组成在三类栖息地之间存在显著差异;(4)随着栖息地的改变,某些取食集团的鸟类也发生了相应的集团改变.
Studies were conducted to investigate the foraging guilds of winter birds in Hangzhou across an urban gradient from November 2001 to January 2002, which includes different urbanization level habitats of building areas, woody patch areas and west mountain areas. The results indicated that : (1)With the increase of urbanization, the numbers of the foraging guild tended to decrease as a whole. (2)With the increase of urbanization, the species number of the foraging guilds tended to decrease as a whole. (3)There was significant difference in the structures of the foraging guilds in 3 habitats. (4)Some kinds of foraging birds changed foraging guilds accordingly with the change of habitats.
