摘要：
This paper discusses a randomized n-species Lotka-Volterra competition system. We show that this system is stable in time average under certain conditions. Furthermore, there is a stationary distribution of this system, if extra conditions are satisfied. Also we give the extinction condition of this system. Finally, numerical simulations are carried out to support our results. (C) 2012 Elsevier Inc. All rights reserved.
