提出了实行计划生育人口复杂巨系统的数学模型 ,它是一组无穷维分布参数一阶线性偏微分方程系统 .该模型含有孩次、节育及绝育等与计划生育有关的系数 ,而 Sharpe-Lotka模型没有 ,因此本文所提出的模型克服了 Sharpe-Lotka模型简单粗糙的不足 .

In this paper,we present the mathematical model of the complex huge sys- tem about family planning′s population that is a differential system with a group of lin- ear partial differential equation of first order.This model consists of some coefficients that concern with sterilization and contraception and fetal order that are not included in Sharpe- Lotka model,and so it overcomes the simplicity and crudity of sharpe- Lotka model.
