植物化感作用与生物多样性

本文简要地阐释了化感作用的含义、基本特征以及作用机制，并结合生物多样性理论，综述了化感作用研究中化感物种的多样性、化感物质的多样性及其释放途径的多样性，具体讨论了化感作用对物种多样性、遗传多样性及生态系统多样性中的种群生态、协同进化、土壤生境、生态系统功能和生物入侵等方面的可能影响。文中提出了化感作用的利用、管理应与生物多样性保护相统一的看法，并指出对化感作用与生物多样性的关系以及相互影响机制进行本质的探索，特别是对植物化感作用的生态服务功能与价值评估与探讨，可为保护生物学和系统生态学提供理论基础，这也是今后工作开展的一个重要方向。

Allelopathic Effect in Plants and Biodiversity

The definition, basic characteristics and fundamental mechanism of allelopathy are illustrated simply. On the basis of correlation with biodiversity theory the diversity of species, allelo-chemicals of allelopathic effect and their released pathways were summarized. Then the possible effects of allelopathy on biodiversity of species, genetic diversity and community ecology, co-evolution, soil habitation, ecological function and biological invasion in biodiversity of ecosystem were discussed concretely. An important idea on the combination between the utilization and management of allelopathy and the biodiversity protection was proposed. Meanwhile an essential study on the relationship and mutual influence mechanism between allelopathy and biodiversity, especially, its service function and values in ecosystem, should be considered a new approach for biological scholars, which will establish a academic basis for protection biology and chemical ecology.
