摘　　要：通过对吉林省长春市采集到的11只蝙蝠标本的外形、头骨、牙齿和阴茎骨进行测量与对照,鉴定为东方蝙蝠(Vespertilio sinensis),是吉林省翼手目新纪录。用实时录音的超声波仪录制其正常飞行状态下的回声定位声波。结果表明,东方蝙蝠发出短的、宽带的、多谐波的陡坡调频型回声定位声波,能量主要集中在第1谐波。起始频率为83.66±2.08 kHz,峰频为34.54±0.88 kHz,终止频率为24.78±0.41 kHz,带宽为58.84±2.10 kHz,声脉冲持续时间和声脉冲间隔分别为2.63±0.27 ms和61.67±7.5 ms。Eleven bats were collected from the eaves and walls in Sheling town in Changchun City of Jilin Province. Based on the characteristics of morphology, skull, teeth and baculum, the species was identified as Vespertilio sinensis and it was first recorded in Jilin Province. Although widely distributed in the provinces around Jilin Province, the north of Korea and Far East of Russia, the echolocation calls of this species has rarely been examined. In this study, we recorded the echolocation calls of this species while the bats flew out from the eaves. The calls during flight were short, broadband, steep FM signals, with the energy concentrated in the first harmonic. The starting, peak and ending frequencies were 83.66 ± 2.08 kHz, 34. 54 ±0. 88 kHz and 24.78±0.41 kHz, respectively. The duration was 2.65 ±0. 27 ms, and bandwidth was 58.84 ± 2. 10 kHz. The echolocation calls of this species in Jilin were significantly different from those of the same species in Hokkaido, Japan, which produced long, gentle FM/QCF signals. The reason for the difference was probably due to geographical segregation of populations.
