摘要

摘要: 人工湿地氮转化途径主要包括微生物的硝化反硝化作用、植物的吸收和湿地基质的吸附等。水位变化作为水文机制的重要方面，直接或间接的影响人工湿地环境各种形态氮质和量的变化。阐述了人工湿地氮转化机理和影响因子，并从湿地环境植物形态特征及生长发育、理化性质（DO、pH、Eh）和微生物的硝化反硝化强度三方面对水位变化响应的角度总结了国内外的相关研究进展，并提出研究中存在的问题和相关的建议：加强不同水位变化模式（水位变动幅度、水位变动周期）对人工湿地各种形态氮转化影响的研究，通过水位调控改善植物生长策略、提高微生物硝化反硝化强度，实现增强人工湿地脱氮功效的目的。

Abstract: The major nitrogen transformation pathways in constructed wetlands include nitrification and denitrification of microbe, plant uptake and adsorption by substrate. As an important aspect of hydrological processes, water-level change can directly or indirectly affect the quality and quantity of nitrogen in various forms. The nitrogen transformation mechanism and influence factors of constructed wetlands were expounded, and the relevant research achievements of the wetland plants' morphological characteristics and growth, the physical and chemical properties (DO, pH, Eh), and the intensity of microorganism nitrification and denitrification in response to water-level changes in wetland were summarized. The problems existing in previous studies were pointed out and some suggestions put forward, including strengthening researches on the influence of different water-level change modes (such as change range and period) on nitrogen transformation in various forms in the constructed wetlands, and increasing the nitrogen removal effect through improving plant growth and enhancing the intensity of microorganism nitrification and denitrification with water level control.
