title: [Allelopathy of invasive weeds: a simulation study with cellular automata model].
abstract: Cellular automata model is a simulation approach to describe the complicate behavior of a system, and suitable to study the spatial and temporal dynamics of plant community. In this paper, the model was used to simulate the different sensitivity toall invasion process of an allelochemicals-containing exotic species to the community of two native species with different sensitivity to allelochemicals, and the spatial and temporal dynamics of native and invasive species. The simulation was conducted by biological response and negative exponential distribution models, and the results showed that exotic species could successfully invade the community of two native species with different sensitivity to allelochemicals, but only coexist with one sensitive and one resistant species. The resistance of plant community to invasive weeds depended on its species function structure.
