相互作用的人群模型。他们试图获得对初始条件和假设细节相当不敏感的总体的显着特性。在对人口动态进行“统计机械”处理时，他们将 LVM 视为首要原则。然而，在 Lotka-Volterra 类型模型中，指定动力系统的参数是以群体而非个体的形式给出的。也就是说，每个物种的种群增长率（称为 Mal·husian 参数）是根据种内和种间相互作用给出的，而不是根据物种每个个体的特征（例如生存力、繁殖力、运动性和社会行为（例如帮助或攻击邻居））给出的。从这个意义上说，他们的处理方法并不完全是统计机械的，而是
models of interacting populations. They tried to obtain salient properties of popula tions which are rather insensitive to initial conditions and details of assumptions. In their 'statistical mechanical' treatment of population dynamics, they regarded LVM as a first principle. However, in Lotka-Volterra type model parameters specifying the dynamical system are given in terms of groups and not in terms of individuals. Namely, the growth rate of population of each species called Mal thusian parameter is given in terms of the intraspecific and interspecific interaction, and not in terms of the trait of each individual of a species, such as viability, fecundity, motility, and social behaviors such as helping or attacking towards neigh bors. In this sense their treatment is not fully statistical mechanical, but rather
