摘　　要：本文以SAS Lab鸟类声谱分析软件对采自青藏高原黑马河、玛多与花石峡、沱沱河的白腰雪雀不同地方种群的鸣叫与鸣唱的复杂性进行了分析 ,发现白腰雪雀的鸣叫相对变化率随着采样量的增加由 0 5 2 2迅速降低到 0 1 2 7和 0 1 1 9,表明其鸣叫声组成中音节类型较少。同时发现其声谱图结构比较简单 ,表现出高度的音节重复并多有谐波的现象。鸣唱结构相对复杂 ,不同鸣唱音节数随鸣唱曲目的增加 ,开始有明显的增加 ,当鸣唱曲目增加到一定值时 ,不同音节数的增加趋于平缓 ,几乎保持稳定 ;野外未发现任何相同的鸣唱型 ,但在不同鸣唱型之间具有不同程度的音节共享现象。依据雷富民等 (2 0 0 3)对鸟类鸣唱多样性和复杂性的评述 ,白腰雪雀鸣唱的结构模式符合“多音节序列不稳定变化型” ,其鸣唱曲目中音节的转换形式为“序列鸣唱”。然而 ,鸣唱模式中音节类型的有限性和鸣唱型的高度多样化表明 :白腰雪雀鸣唱的复杂性不仅体现在鸣唱型内较丰富的音节组成 。This paper analyzes the diversity and complexity of calls and songs of the white rumped snow finch recorded from Heimahe, Maduo, Huashixia, and Tuotuohe of the Tibet Plateau using SAS Lab avian song analysis software The results revealed that the value of the call rate changes quickly from 0 522 to 0 127 and 0 119, which reveals that there are fewer notes in calls. Calls were found from sonograms to be very simple with more harmonics and with high note repeat. Songs are more complex. The numbers of syllable types increase at the beginning period but are more stable when more song types are calculated. No one identical song type was discovered during the field recording and song analysis. However, different song types share more syllables. According to the diversity and complexity pattern reviewed by Lei et al. (2003), the song complexity patterns of the white rumped snow finch may belong to the “unstable changing in sequence of polysyllable” pattern with typical “serial song” from immediate variety of syllables. Futhermore, the limited syllable during a song type and the very complex and diversified song type in song repertoire suggest that song complexity of the white rumped snow finch may be caused by not only more rich syllables within a song, but also and even more for the organization and output of syllable sequence among different song types
