物种相互作用的生态学理论主要依赖于Lotka、Volterra、Nicholson和Gause（例如，1973年5月）的竞争和捕食模型。这些模型一般忽略了空间结构，尤其是斑块性。本文引入细胞自动机（CA）作为一类新的空间种群相互作用模型。我们将讨论CA模型与更熟悉的反应扩散和斑块占用公式之间的关系，并将简单CA竞争模型的结果与相应的马尔可夫链斑块占用模型进行比较。这个比较揭示了一些因素，这些因素决定了什么时候简单的斑块占用模型是成功的近似，什么时候空间显式CA模型更合适。
The ecological theory of species interactions rests largely on the competition and predatorprey models of Lotka, Volterra, Nicholson, and Gause (e.g., May 1973). These models neglect spatial structure in general, and patchiness in particular. In this paper we introducecellular automata(CA) as a new class of models for population interactions in space. We will discuss the relations between CA models and the more familiar reaction-diffusion and patch-occupancy formulations, and compare the results of a simple CA competition model to the corresponding Markov chain patch-occupancy model. This comparison reveals some of the factors that determine when simple patch-occupancy models are successful approximations, and when spatially explicit CA models are more appropriate.
