摘　　要：化感作用已成为园林植物相互关系研究的热点和焦点之一。从化感作用的概念、争论焦点、研究方法、化感物质的成分及作用机制等方面系统地总结了国内外园林植物化感作用的研究成果,指出现阶段研究存在的6个方面问题并进行了分析讨论:①科学文献少,经验材料多,研究不够深入;②研究对象尚待明确,应更多基于指导实践的目的,选择实际中人工配置频繁的观赏种及品种进行研究;③化感作用的证实缺乏说服力,应区分化感作用与其他植物应激机制,注重研究化感在整个植物相互关系中的作用和地位;④实验室和自然环境之间的差异导致说服力降低,建议将实验室研究与自然环境模拟实验相结合来进行研究;⑤化感作用物质的报道少;⑥化感物质的作用机制研究不够深入,应深入研究园林植物化感作用的机理及一般规律,以指导园林植物配置。Allelopathy of ornamental plants has becomes a focus topic in recent years.This paper systematically reviewed the domestic and overseas researches on the conception,arguments and methods of allelopathy,components and mechanism of allelopathic substances.It is concluded that there were six problems in the research of this field.（1）Little scientific literatures and comparatively more empirical materials could be found,and researches were not thorough enough.（2）Research objects need to be defined,and the research should focus on the application of allelopathy in the plant arrangement of landscape gardens.（3）The existence of allelopathy in the real environment needs to be confirmed.Allelopathy should be distinguished from other stress mechanisms in future researches,and the emphasis of researches should be the roles of allelopathy in interaction.（4）The differences of conditions between laboratory studies and natural environments led to less convincing experimental results.The laboratory methods should be combined with natural simulation test in the future allelopathy researches.（5）The reports about allelochemicals were few.The allelochemical researches should focus on the ornamental plantsand their varieties.（6）The research on the mechanism of allelopathy was not thorough enough.Researchers should deepen the research on the mechanism of the allelopathy and find general rules in order to guide arrangement of ornamental plants.
