在植物入侵过程中，河流可能起到扩散剂的作用，通过水支持水溶物向下游移动（如Stani-forth & Cavers, 1976; van der Pijl, 1982; Schneider & Sharitz, 1988; Skoglund, 1989）。此外，破坏性洪水造成的周期性扰动通常会破坏或破坏大部分河岸植被（Ellenberg, 1988），从而创造出开口，为幼苗的建立和随后的定植提供合适的栖息地和有利的营养条件（Walker, Zasada & Chapin, 1986）。因此，外来物种被成功引入并归化的河岸栖息地可能成为随后传播到邻近景观的焦点（Pyšek, 1991,1993）。
In the process of plant invasion rivers may act as dispersal agents, supporting downstream movement of diaspores by water (e.g. Stani-forth & Cavers, 1976; van der Pijl, 1982; Schneider & Sharitz, 1988; Skoglund, 1989). Moreover, periodic disturbances resulting from destructive flooding generally destroy or damage a large part of riparian vegetation (Ellenberg, 1988) thus creating openings that provide suitable habitats and favourable nutrient conditions for seedling establishment and subsequent colonization (Walker, Zasada & Chapin, 1986). Consequently, riparian habitats into which an alien species was successfully introduced and naturalized may serve as foci for subsequent spread into the adjacent landscape (Pyšek, 1991, 1993).
