摘要
用抛物方程的比较原理和上、下解方法，证明了一类半线性时变种群扩散系统广义解的唯一性。
The paper proves the uniqueness of the solution for a class of semilinear time varying population systems with diffusion by the comparison theorem of parabolic equation and the method of super solution and lower solution.It provides a theoretical base for further study of population system.
