摘　　要：对灰眉岩鹀(Emberiza godlewskii)种群内鸣声的空间格局进行了研究。共获得24只个体的录音,平均每个个体录音34句。每个句子有多个音素构成,依据音素的形态,将其划分为7种类型,计算每种类型的音素在个体鸣唱中出现的比率。依据个体使用不同类型音素比率的差异,计算个体间的鸣声相异性指数。结果表明:邻居间鸣声的相异性指数(0.224±0.076)与非邻居间(0.245±0.050)无显著差异(T检验,P=0.095);鸣声相异性指数与空间距离无线性相关性(Mantel检验,P=0.227)。本研究区内灰眉岩鹀鸣声空间格局缺乏规律性,可能是生境受人为干扰严重,种群年际间个体变动大所致。An in situ recording was conducted to study the spatial pattern of son g sharing within Emberiza godlewskii population.A total of 24 individuals’ son gs were recorded,averagely 34 songs each individual.Each song consisted of mul ti-elements,and the elements were grouped by shape and classified into seven b road categories.The song dissimilarity index was computed for each pair of the individuals,according to the usage of each element category.No significant dif ferences were observed in the song dissimilarity index between neighbors （0.224 ±0.076） and non-neighbors （0.245±0.050） （T test,P=0.095）,and al so,there wa s no significant correlation between the song dissimilarity index and spatial di stance （Mantel test,P=0.227）.The song sharing within E.godlewskii popul ation had no definite spatial pattern,possibly due to the excessive human distu rbance on the habitat and the greater annual change of the individuals within th e population.
