摘　　要：通过观察比较秦岭羚牛与黑斑牛羚(Connochaetes taurinus)运用头上2只洞角的争偶攻击行为,采用野外观察与录像观察相结合的研究方法,描述了2种动物的部分攻击行为,通过比较攻击行为差异,证明秦岭羚牛的角在争偶攻击行为中还有瞄准对方角的作用,可以准确的将自己的角顶到对方的角。Golden Takin（ Budorcas taxicolor bedfordi） is a kind of animal with two hole horns,the horn function and structure of the animal were analyzed by comparing with those of blue wildebeest（ Connochaetes taurinus） to attack for mate competition. By combining field and video observation,different aggressive behaviors were carried out between these two kinds of animals. The results demonstrated that the horn of Golden Takin had function to aim at the horn of fighting opponent with higher accuracy.
