| 摘 要： | 论述了湿地氮素通过大气氮沉降、生物固氮、人为氮和径流氮输入等输入途径和植物收获、土壤NH3 挥发、反硝化气态损失、淋滤、径流输出等输出过程以及通过固氮作用、矿化(氨化)作用、硝化作用、反硝化作用等进行生物地球化学循环,提出量化氮与碳、磷之间的关系是目前研究中存在的主要问题,指出在湿地系统内氮迁移量及其与不同环境要素间的关系是下一步研究的主要方向,探讨了湿地氮循环对全球环境变化的影响. |
| 关 键 词： | 湿地 氮循环 矿化 硝化 反硝化 环境变化 |

| Abstract: | This paper illustrates the input ways including elevated N deposition,biological N fixation,man-made N and runoff N input;the output processes including plant harvest,soil NH3 volatilization,denitrification and leaching,runoff output,etc;and biogeochemical cycle of nitrogen through N fixation,mineralization (ammonification),nitrification,denitrification in wetlands as well as the relationship among them.To obtain quantitative relationships of N,C and P is one of the main problems in the present research,in which the key issue is to investigate relations between N migration amount and environmental factors in the wetland system.The influence of wetland nitrogen cycle on the global environment is also discussed. |
| Keywords: | wetland nitrogen cycle mineralization nitrification denitrification environment change |
