通过上下解方法及比较原理,得到了二维扩散Lotka—Volterra竞争系统的渐近传播速度.
The spreading speed of diffusion Lotka-Voherra competition system has been discussed. By using up- per-lower solution technique, comparison principle and some conclusions of the Fisher-KPP equation, the spreading speed of two dimension Lotka-Volterra competition system with diffusion is obtained
