【摘要】 氮是引起水体富营养化的关键生源要素之一。近年来，全球水体富营养化问题依然突出，开展水体氮削减过程及机理研究具有重要意义。被称为“地球之肾”的湿地生态系统具有氮吸收、转化和截留等功能，作为主要初级生产者的湿地植物在其中发挥着重要作用。在分析湿地生态系统脱氮过程的基础上，重点从植物种类及多样性、根系分泌物、植物凋落物等方面阐述了植物调控湿地生态系统脱氮过程的机制，并对未来需要重点关注的问题进行了展望。建议从植物氮偏好性、植物多维多样性、植物-微生物群落相互作用、根系分泌物不同组分、脱氮过程产物组成等方向进一步深入深究脱氮过程的植物调控机制，为湿地生态系统削减氮污染提供理论依据和技术指导。更多还原

【Abstract】 Nitrogen is one of the critical factors that causes water eutrophication.In recent years, water eutrophication in the world is still severe, and it is of great significance to studying the processes and mechanisms of nitrogen removal in water bodies.The wetland ecosystem, known as the kidney of the earth, has the functions of nitrogen absorption, transformation, and interception, and as the main primary producers, wetland plants play a vital role in the nitrogen removal function of wetland ecosystems.This paper analyzes the mechanism of plants regulating the nitrogen removal process in wetland ecosystems, focusing on the effects of plant species and diversity, root exudates, and plant litter on the nitrogen removal process of wetlands, and discusses the problems that need to be focused on in the future.It is suggested to further study the plant regulation mechanism from the aspects of plant nitrogen preference, plant multidimensional diversity, plant-microbial community interaction, different components of root exudates, and product composition of nitrogen removal process, so as to provide the theoretical basis and technical guidance for reducing nitrogen pollution by wetland ecosystems.更多还原
