沉水植物生长和腐解对富营养化水体氮磷的影响机制研究进展

Research advances on the influence mechanisms of submerged plants growth and decomposition on nitrogen and phosphorus in eutrophic water

沉水植物作为湖泊、河流等生态系统的主要高等植物,在修复富营养化水体中的作用日益受到重视,合理利用沉水植物是去除富营养化水体氮磷的有效途径。沉水植物对水体氮磷的迁移转化影响包括生长和腐解两个阶段。文章综述了沉水植物生长对富营养化水体氮、磷的净化效果和净化机制,分析了沉水植物腐解对氮、磷迁移转化的持续影响,并提出了今后沉水植物净化氮、磷的研究方向,为沉水植物推广应用于修复富营养化水体提供理论基础。

As the main higher plants of lakes, rivers and other ecosystems, submerged plants have attracted a great deal of attention in restoration of eutrophic water. Rational utilization of submerged plants is an effective approach to remove nitrogen and phosphorus from eutrophic water. Submerged plants affected the migration and transformation of nitrogen and phosphorus during their growth and decomposition processes. In this paper, the purification effects and mechanisms of submerged plants on nitrogen and phosphorus in eutrophic water were reviewed. The influences of submerged plants decomposition on migration and transformation of nitrogen and phosphorus were analyzed. The possible direction for future research was put forward as well. This paper aims to provide theoretical basis for application of submerged plants in remediation of eutrophic water.
