摘　　要：运用似乎不相关线性模型原理,对具有捕食与被捕食关系的Lotka-Volterra模型的参数给予估计,得到从定量的角度分析种群关系的新途径,为分析具体的应用问题提供了一个新的方法,并对加拿大猞猁与雪兔两种群关系的生态学典型例子进行了具体的定量分析,得出两种群稳定的各项参数估计值。The principle of seemingly unrelated linear model is used to estimate the parameters of the I^tka-Volterra model which has a predator-prey relationship between two species. A new way is found to analyze the relationships of population from the view of quantitation, meanwhile provide a method of analyzing the specific application prob- lems. The typical example of Lynx and Snowshoe hare is given to check the method, and the estimated values of oarameters are finally obtained through calculation.
