摘要
研究周期竞争Lotka-Volterra系统，改进了两种群竞争排斥的充分条件，并且把竞争排斥原理推广到多种群的情形，给出了多种群系统中种群持久和灭绝的充分条件．
A periodic competitive Lotka-Volterra system is considered in this paper. Sufficient conditions for principle of competitive exclusion are improved. The principle of competitive exclusion is generalized to multi-species case, and sufficient conditions for permanence and extinction of multi-species periodic competitive system are given.
