摘　　要：植物个体间的竞争是植物种群和群落中的普遍现象,一直是生态学家关注的焦点,尤其是植物在生长过程中与邻体的地上竞争。在环境水分胁迫或营养胁迫条件下,植物根系间的地下竞争同样重要。然而,有关植物体地上、地下竞争模式的相关理论一直存在分歧和争论。该文扼要介绍了植物地上、地下竞争的概念及模式,简要阐述了植物对称性竞争与非对称性竞争相关研究的理论模型及其检验方法,概述了影响植物间竞争甚至改变竞争模式的主要因素及其意义,讨论了研究物种对称性竞争和非对称性竞争的模式和机制对生态学其他研究领域的影响和重要意义,并对植物对称性竞争与非对称性竞争的相关研究进行了展望。Competition among plant individuals is a critical process within a population and community and has long been a research focus in ecology, with particular attention on aboveground competition during growing seasons. The belowground competition of plant roots is equally-important, especially under water and nutrition stresses. Yet, our theoretical foundations for understanding the similarities and differences on belowground vs. aboveground completions remain immature. In this paper, we review up-to-date concepts and the understanding of aboveground and belowground competitions, summarize the relevant theories and associated conceptual frameworks, and pre-sent ways for testing these models for symmetric/asymmetric competitions. Additionally, we discussed the major variables involved in these processes and models. Finally, we shared our views on modeling competition for ad-vancing ecological research in the future.
