昆虫种群死亡过程的数字模拟

A MATHEMATICAL SIMULATION TECHNIQUE FOR MORTALITY OF THE INSECT POPULATION

昆虫种群的死亡过程,是影响种群数量变动的一个重要因素。在正确地构造昆虫种群的生长发育模型,并使种群发育时间的理论分布拟合实际资料的同时,必需正确地考虑死亡个体在种群中对数量变动的作用,才有可能全面地表达种群的增长与消亡的数量动态。 有关模拟种群的死亡过程的讨论已发表很多,其中多数只讨论种群总的死亡率(如Pielou,1969)。也有过一些比较详细的结果。

Most of simulation models for the mortality of the insect population issued in references are either of whole population, or of the mortalities in days. This paper deals with a mathematical simulation technique for the mortality in insect status, based on the "Boxcar Train" model. That is a simulation method of classified dying processes with the geometric progression form.
