| Abstract: | In this paper, we study the general nonautonomous Lotka-Volterra competitive ecosystems. Some new criteria for the uniform persistence of a part of species and the extinction of other part of species are established. These results improve and extend the recent ones obtained by Montes de Oca and Zeeman in
