摘 要:依据1983—1993年的调查资料,初步分析了北京地区鸟类区系的特征和华北两个亚区在北京的分界线。提出北京鸟类区系具有比较浓厚的北方鸟类区系和季风区鸟类区系的特点,位于华北区两个亚区接界处的特征也十分突出,且与东北区长白山亚区和蒙新区东部草原亚区鸟类区系关系密切。初步建议将两个亚区的分界线划在张坊—长操—高崖口—长陵—石城—古北口—北庄—熊儿寨—靠山集一线。Based on an avifauna survey in Beijing area which had been undertaken from 1983 to 1993, a preliminary analysis of characteristics of the avifauna and the dividing line between Huang-Huai Plain Subregion and Loess Plateau Subregion in Beijing was made. It was shown that in Beijing avifauna there were distinct characteristics of the North China avifauna, the Pacific monsoon area avifauna and the contact zone avifauna between Huang-Huai Plain Subregion and Loess Plateau Subregion. Moreover, some close relationships were found between Beijing fauna and Changbai Mountain Subregion fauna, as well as between Beijing fauna and East-Meadow Subregion fauna. It might be more reasonable that the two subregions be divided by a line along Zhangfang, Changcao, Chanling, Shicheng, Gubeikou, Beizhuang, Xongerzhai and Kaoshanji.
