沉水植物对城市景观水体净化机理及影响因素的研究进展

Research Progress on Purification Mechanism and Influencing Factors of Submerged Macrophytes on Urban Landscape Water

从城市景观水体的净化机理及影响因素等方面综述了研究进展,并对沉水植物的研究方向进行了展望。沉水植物净化机理主要包括吸收、分泌与竞争作用、生境改善作用和生物载体作用等方面;影响净化水体因素主要为性状特征、生长基质、不同水体条件及水生动植物间的相互作用等,提出了建议:进一步加强选育沉水植物优先级或先锋种、构建附植生物群落和组合群落的研究,同时结合碳达峰-碳中和的背景,以实现沉水植物更好的固碳、增加碳汇量的研究也会是生态修复的重要研究方向。

The research progress of purification mechanism and influencing factors of submerged macrophytes on urban landscape water was summarized,and the future research directions of submerged macrophytes was prospected in the paper.The purification mechanism of submerged plant mainly includes absorption,secretion and competition,habitat improvement effect and biological carrier,etc.Factors affecting purifying water include the submerged plant self-trait characteristics,matrix,different water conditions and the interactions between aquatic animals and plants,etc..Then,it is suggested to strengthen the research of priority or pioneer species selection of submerged macrophytes,the construction of attached biological community and combined community.Furthermore,combined with the background of carbon peak carbon neutralization,how to achieve better carbon sequestration and increase carbon sink of submerged macrophytes will be an important research direction of ecological restoration.
