摘要：

<正> 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).The growth of body weight is divided into two stages:the young (0-29 days of life) and the juvenile (29-80 days of life). Body weight remains stable in the adult stage (after 80th day of life). The growth of body weight is quick in 0-29 days and slow in 29-80 days. A model of growth is constructed with the boundary problem of the Logistic equation (1)(1)wherew = body weight (g.)t= age in dayk= saturation boby weightr1 = instrinsic growth rateWi = mean born body weightws = mean observed value of body weight at 29th day of lifefor 0-29 days. The parameter r1 is only estimated according
