摘　　要：全球环境变化一直是人们广泛关注的热点问题,由人类活动和化石燃料燃烧引起的温度持续升高、温室气体排放增加、极端天气频繁发生等现象对土壤理化性质及微生物活动产生深刻影响。N_(2)O作为一种具有强增温潜势的温室气体,对生态环境造成极大威胁。因此,全面深入地探究全球变化下不同环境因子对土壤N_(2)O排放的影响有重要意义。论文综述了模拟全球变暖、CO_(2)浓度倍增、降水格局改变以及氮沉降对土壤N_(2)O排放的影响及微生物作用机制,阐述不同变化因子对N_(2)O排放的交互效应。温度升高、CO_(2)浓度增加和氮沉降均能促进N_(2)O排放,但不同变化因子交互作用对N_(2)O排放的影响存在差异。未来应加强对多个变化因子交互作用的研究,不仅有助于进一步了解N_(2)O产生的影响因素,而且能为将来土壤生态系统对全球环境变化的响应研究和预测模型的建立提供理论基础。Global environmental change has been a hot issue of widespread concern. Phenomena, such as continuous temperature rise, increase of greenhouse gas emissions and frequent occurrence of extreme weather caused by human activities and fossil fuel burning, have a great impact on soil physical and chemical properties and microbial activities.As a greenhouse gas with strong warming potential produced, N_(2)O poses a great threat to the ecological environment.Therefore, it is of great significance to comprehensively and deeply explore the impact of different environmental factors of global environmental change on soil N_(2)O emission. In this review, the effects of simulated global warming,CO_(2) concentration doubling, precipitation pattern change and nitrogen deposition on soil N_(2)O emission and microbial mechanism were summarized, and the interaction effects of two different global environmental change factors on N_(2)O emission were expounded. The increase of temperature, CO_(2)concentration and nitrogen deposition could promote N_(2)O emission, but the interaction of different change factors has different effects on N_(2)O emission. In the future, we should strengthen the research on the interaction of multiple change factors, which will not only help to further understand the influencing factors of the production of N_(2)O, but also provide a theoretical basis for future research on the response of soil ecosystem to global environmental change and the establishment of prediction models.
