摘要: 动物生长数学模型的研究是生态学和遗传学理论中重要的研究领域之一。广泛地研究T动物生长过程(Wemouth等,1930; Laird, 1964, 1965a, 1965b, 1966a, 1966b; Laird等,1965; Laitd等,1967; Kidwell等1969)。高原鼠兔(Ochotona curxoniae)是高寒草甸生态系统的主要初级消费者之一(刘季科,1982),定量地探讨其体重生长规律,是估计种群的生物生产量和能量动态必不可少的资料。有关自然条件下,高原鼠兔体重生长的研究,还尚乏报道。本文旨在报道其自然种群中,个体平均体重生长的逻辑斯蒂一指数饱和(Logistic-exponential saturation)动态数学模型,为分析高原鼠兔种群生产量动态提供子模型,亦为科学地制订管理该鼠种的对策提供理论根据。

Abstract: Many studies on models of growth of body weight in animals have been reported. This paper provides a model of growth of body weight in plateau pika (Ochotona curzoniae) under natural conditions. The data of growth of body weight in plateau pikas were obtained from the Haibei Alpine Meadow Ecosystem Reseach Station, Academia Sinica, from May to September in 1979 and from April to October in 1980 and 1981 (Tab. 1 and Tab. 2).

Key words: Plateau pika, Ochotona curzoniae, Population productivity ecology, Body Weight growth, Dynamic mathematical model
