摘　　要：随着物理科学的发展,偏微分方程的应用范围越来越广泛。而人口问题始终是制约我国发展的关键因素,预测我国人口的发展趋势,是我国人口发展战略的核心内容之一。应用一维迁移方程导出人口问题的数学模型,并得出偏微分方程的解。With the development of physical science,the application of partial differential equations is more and more extensive. Population problem is always the key factor that restricts the development of our country. It is one of the core contents of China＇s population development strategy to predict the development trend of China＇s population. In this paper,the mathematical model of population problem is derived by using one dimensional transfer equation,and the solution of partial differential equation is obtained.
