摘　　要：棉田间套复合体系是以提高棉田整体经济效益为目标而发展起来的现代农业种植体系,不仅能有效地缓解粮棉、经棉和果棉争地矛盾,实现棉花与其他作物同步增产增收,还可以作为协调粮食安全与生物多样性保护之间矛盾的有效手段。近年来,棉田间套复合体系越来越受到人们的重视和应用。本文系统总结了棉田间套复合体系提升生态系统服务功能的研究进展,如增加生物多样性、增加系统生产力和经济收益、提高光热利用效率、改善棉花品质、控制病虫草害等。并从地上光热资源和地下根系生态位互补、种间促进作用增加资源有效性、化感作用减轻病虫害最终促进邻居植物生长方面解析其潜在的生态学机制。最后对今后的研究方向进行了展望。Cotton-based intercropping systems are one of modern agriculture farming systems aiming at improving overall economic profitability of cotton field,which not only release the competition for land between other crops and cotton and increase growing area and yield of both crops,but also represent a mechanistic approach to reconciling crop production and biodiversity conservation.Recently,cotton-based intercropping systems have been widely focused and applied.Here,we reviewed the potential of cotton-based intercropping systems to reinforce agroecosystem services and functioning,including promoted plant biodiversity,improved overall productivity and economic profits,increased light use efficiency,improved cotton quality,reduced pest and disease occurrence,and suppressed weed growth.Further,the underlying mechanisms behind the enhancement of agroecosystem services and functioning by cotton-based intercropping systems through niche complementarity,interspecific facilitation,and allelopathy between intercropped species were summarized in the paper.Finally,the research prospects were also pointed out.
