摘　　要：利用蝙蝠超声波探测器和CoolEditor 2 0 0 0声波分析软件研究了皮氏菊头蝠 (Rhinolophuspearsoni)的超声波信号 ,同时在野外研究了其捕食行为。研究结果显示皮氏菊头蝠是FM/CF/FM型的食虫蝙蝠。其回声定位信号的CF声波两端均附有短暂的FM信号 ,每次声波脉冲包含 2段信号 ,第 1段信号的CF频率为 (6 1 0 8±0 0 19)kHz ,持续时间为 (4 6 85± 3 72 )ms ;第 2段信号的CF频率为 (6 0 97± 0 0 3)kHz ,持续时间为 (35 12± 2 6 7)ms。在对皮氏菊头蝠的捕食行为研究中 ,通过运用生物多样性指数分析和Spearman相关性分析 ,结果表明皮氏菊头蝠在常绿阔叶落叶混交林中主要以式捕食鳞翅目 (Lepidoptera)、鞘翅目 (Coleoptera)等中型个体的昆虫 ,对食物种类及其体型具有选择性。此外 ,其形态与回声定位功能之间还表现出相关性。We used the Bat Sound Detector and the Professional Recorder to collect the echo of Rhinolophus pearsoni ,and then analyzed the echoes by the software Cool Editor 2000.It showed that this bat species is a kind of FM/CF/CM bat,the echolocation calls comprise two constant frequency signals which two modulated frequency signals attached.The frequency of first CF signal is (61 08±0 019)?kHz,the frequency of second CF signal is (60 97±0 03)?kHz.After researched the foraging behavior of R pearsoni in field,meanwhile,analyzed the food compositions by used Shannon Weiner diversity index and Spearman correlation analyses,it suggested that this bat captured the mid sized insects of Lepidoptera and Coleoptera etc.by flycatching method mainly in evergreen and deciduous broadleaf forest in summer.This species of bats showed feeding selective to the types and body size of prey.Meanwhile,it suggested that there maybe relativity between the echolocation signals function and morphological feature of R pearsoni .
