摘　　要：氮沉降作为土壤生态系统中的一个关键生态因子,显著影响生态系统的结构和功能。为系统阐述氮沉降对土壤呼吸的影响,综述了氮沉降对土壤根系、土壤微生物、土壤动物呼吸以及土壤含碳矿物质化学氧化的影响,分析了不同氮沉降量梯度对土壤呼吸的具体影响,并对土壤呼吸领域未来的研究方向作出展望,以期为后续深入监测、研究土壤呼吸及相关生命活动提供理论参考。Nitrogen deposition,as a critical ecological factor in the soil ecosystem,significantly affects the structure and function of ecosystems.To systematically elucidate the impact of nitrogen deposition on soil respiration,the effects of nitrogen deposition on soil root respiration,soil microorganism respiration,soil animal respiration and chemical oxidation of soil carbon‑containing minerals were reviewed,and the specific effects of different nitrogen deposition gradients on soil respiration were analyzed.In order to provide a theoretical reference for subsequent in‑depth monitoring and research of soil respiration and related life activities,the future research directions in the field of soil respiration were prospected.
