摘　　要：针对民航业、农业中的人鸟冲突问题,在保护鸟类的前提下,以鸟声驱赶设备为代表的无伤害驱鸟技术成为近年的研究热点。收集北京常见的鸟类——喜鹊Pica pica、灰喜鹊Cyanopica cyana的正常鸣声、受惊鸣声及其天敌苍鹰Accipiter gentilis的正常鸣声进行研究。利用声谱分析方法测量音节的持续时间(Ds)、主能峰频率(Fhp)、基频(Ff)、组成句子的音节个数(Ns.v)和句型等声学特征参数。发现北京地区所采集上述鸟种的鸣声句法结构简单,句型为相同音节的不断重复。在利用鸣声录音制作鸟声驱鸟设备时,此类鸟声便于编辑、修改和使用,并可通过变换多种方式提高使用效果,从而为缓解人鸟冲突提供更多无伤害方法建议,更好地保护鸟类。Bird calls become hotspot in mitigating the conflicts between birds and humans,especially in agriculture and civil aviation.The study was conducted by recording and analyzing normal calls and scared calls of Pica pica and Cyanopica cyana,and normal calls of Accipiter gentilis in Beijing.The acoustic characteristics of all the records were measured in duration of syllable（Ds）,frequency of the highest power peak（Fhp）,fundamental frequency（Ff）,number of syllables in verse（Ns.v）and verse type.The structure of all the verses is simply formed with repeat syllables.The results will be useful in giving suggestions on utilizing the calls and promoting the effects,so that to facilitate the comprehensive control and application on conflicts between birds and humans.
