生物群体有限增长的条件

CONDITIONS OF FINITE GROWTH FOR ECOLOGICAL GROUPS

用数学方法研究了生物群体的增长问题，考虑非齐生灭过程的系数与真分布的关系，获得了使生灭过程有真分布的普遍性条件。

In this paper, the growth problem of ecological groups was discussed uppon applying mathematical metheods. The relationship between sure distribution and coefficients of non homogeneuous Birth and Death processes was considered. We obtained general conditions so that Birth and Death processes have sure distribution. Based uppon these properties the growth of ecological groups can be finite.
