摘要: l984-1987年在青海湖黑马河湖滨地区,以耳标观察法对高原鼠兔繁殖期交配关系的研究表明:高原鼠兔种群中单婚制占39.73%;一夫多妻(2-5)占45.21% ;二夫一妻和多妻(2-4)占l5.07%,其中2只雄鼠必有1只为主雄,另1只为次雄。

Abstract: Adult sexual behavior and mating system in a marked population of plateau pika(Ochotona curzoniae),using marked ear-tag methods,were studied for a 4-year period.1984-1987 in Heimahe of Qinghai Lake. One male associated with one female(monogamy)is 39.73% of the pulation of plateau pika in the breeding season,and with two females or more than two (Polygamy)is 45.21% at the same home range or in different home ranges Another phenomenon is that sometimes there were more than one male, but among them one must be the dominant,which15.07% of the mating system of the breeding popu1ation.

Key words: Plateau pika, Mating system, monogamy, polygamy
