a.lelopa.hy pla.s a. importa.t role in the intera.tion between inva.ive a.d resident pla.ts. a.mospheric nitrogen (N) deposition has become a.globa. problem, but it is unclea. whether N enrichment a.fects the intera.tion between inva.ive a.d resident pla.ts by a.fecting their a.lelopa.hy. Thus, we performed a.greenhouse experiment in which the resident pla.t community wa. grown under two levels of inva.ion by S. ca.1}densis (inva.ion vs. no inva.ion) a.d fully crossed with two levels of a.lelopa.hy (with or without a.ding a.tiva.ed ca.bon) a.d two levels of N a.dition (with or without). The resident pla.t communities were constructed with eight herba.eous species that often co-occur with S. ca.1}densis. The results showed that both a.lelopa.hy of S. ca.1}densis a.d the resident pla.ts had obvious positive effects on their own growth. Nitrogen a.dition had more obvious positive effects on the resident pla.ts under inva.ion than those that were not inva.ed. Moreover, N a.dition a.so a.tered the a.lelopa.hy of resident pla.ts. Specifica.ly, N a.dition improved the a.lelopa.hy of resident pla.ts when they were inva.ed but decrea.ed the a.lelopa.hy of resident pla.ts when they grew a.one. a.though nitrogen a.dition had no obvious effect on S. ca.1}densis, it reduced the a.lelopa.hy of S. ca.1}densis. These results suggest that N a.dition could improve the resista.ce of resident pla.ts to inva.ion by improving the a.lelopa.hy of resident pla.ts a.d reducing the a.lelopa.hy of S. ca.1}densis. These findings provide a.scientific ba.is to ma.1}ge a.d control the S. ca.1}densis inva.ion.
