摘要
于2003年7月至2004年9月调查北京市区21个绿化带内利用植物鸟类和现有树种中鸟类食源树种的种类和数量,记录到利用植物鸟类52种,占栖息于市区绿化带内被调查鸟类的40·63%;鸟类食源树种48种,占市区绿化带内树种的54%。对目前城市绿化中存在的问题进行探讨,提出通过绿化树种的选择与搭配来招引城市鸟类的措施,以期为北京市生态城市建设提供理论依据。
The present paper investigated and analyzed species and quantities of the birds utilizing plants as total or part of their foods and the bird-feed trees at 21 separating green belts of Beijing urban area during the period between July 2003 and September 2004. Totally 52 birds eating seeds or fruits of plants and 48 bird-feed trees were recorded, and they accounted for 40.63% of birds habitated and 54% of the total trees appeared in the green belts, respectively. Based on the investigation and the analysis, problems existing in afforestation of Beijing urban area were discussed and measures of attracting urban birds through selections and arrangements of tree species were proposed. Therefore, results of the studies would provide theoretical bases for the ecological city constructions of Beijing.
