摘　　要：2014年3-5月,利用计算机声音分析技术对黑鹳(Ciconia nigra)育雏期的鸣声进行了分析和研究.结果表明:黑鹳育雏期的鸣声可分为正常鸣叫声和惊恐声2种类型,二者语句类型大致相同,无明显的差别,均为首音素之后接着出现不定个数的凸型音素,结尾时都是平型音素,总体的趋势都是声音由低到高,再由高到低的一个渐变过程;句子持续时间、句子中音素个数和音素间的时间间隔在正常鸣声与惊恐声间无显著性差异(P>0.05);但音素持续时间、最低频率和最高频率差异极显著(P<0.01).黑鹳主要通过音素的重复,即改变首音素后的平型音素或凸型音素的个数实现句型的改变,以表达不同的含义.The brood stage song of black stork were measured and analyzed during March to May, 2014. The results showed that：the brood stage song could be divided into two types including normal songs and scared calls,which had no obvious difference in the structure of the verses that the convex type note came after first note and end with flat note. The overall frequency trend on the song was being from low to high and then high to low. There was no significant difference between normal songs and scared calls in du- ration of verse,number of notes song and time interval between the notes（P〉0.05）. By comparison,there were highly significant differences in duration of note, maximum frequency and minimum frequency（P〈 0. 01）. Different meanings could be conveyed by different the verse type or note repetition in black stork, namely that the verse type could be changed by changing the number of convex type note and flat type note.
