Background  Although plant diversity is postulated to resist invasion, studies have not provided consistent results, most of which were ascribed to the influences of other covariate environmental factors.    Methodology/Principal Findings  To explore the mechanisms by which plant diversity influences community invasibility, an experiment was conducted involving grassland sites varying in their species richness (one, two, four, eight, and sixteen species). Light interception efficiency and soil resources (total N, total P, and water content) were measured. The number of species, biomass, and the number of seedlings of the invading species decreased significantly with species richness. The presence of  Patrinia scabiosaefolia  Fisch. ex Trev. and  Mosla dianthera  (Buch.-Ham. ex Roxburgh) Maxim. significantly increased the resistance of the communities to invasion. A structural equation model showed that the richness of planted species had no direct and significant effect on invasion. Light interception efficiency had a negative effect on the invasion whereas soil water content had a positive effect. In monocultures,  Antenoron filiforme  (Thunb.) Rob. et Vaut. showed the highest light interception efficiency and  P .  scabiosaefolia  recorded the lowest soil water content. With increased planted-species richness, a greater percentage of pots showed light use efficiency higher than that of  A .  filiforme  and a lower soil water content than that in  P .  scabiosaefolia .    Conclusions/Significance  The results of this study suggest that plant diversity confers resistance to invasion, which is mainly ascribed to the sampling effect of particular species and the complementarity effect among species on resources use.
