Abstract: According to A = P + R energy balance equation, the energy flow through the population of plateau pika, a dominant and widespread species in the Kobresia humilis meadow, has been studied.The research area is located at the Haibei Alpine Meadow Ecosystem Research Station (Lat. 37°29’-37°45’N, Long. 101°12’-101°33’E) with an altitude of about 3250 meters above sea level.

摘要: 本文对栖息于高寒草甸优势种小哺乳动物——高原鼠兔(Ochotona curzoniae)种群的密度、食物的摄入、消化和同化、平均每日代谢率(ADMR)、每日能量收支(DEB)、种群的生产量(P)和呼吸量(R)进行了长期研究的基础上,按照 A=P+R的途径,估计了通过高原鼠兔种群的能流。
