摘　　要：火山活动是地球深部碳循环的重要环节,火山区不仅在火山喷发期能够释放温室气体,而且在休眠期也能向大气圈中释放大量的温室气体。在当前全球温室气体减排的背景下,定量化地研究火山区对大气圈温室气体含量增加的贡献,对于识别自然因素和人类因素碳排放的相对规模、为国际碳排放谈判积累基础数据等均具有至关重要的科学价值和现实意义。本文对火山区温室气体的排放方式与特征、温室气体释放通量与成因的研究方法进行了简要概括,并综述了中国新生代典型火山区温室气体释放通量与成因的研究成果。结合国外温室气体排放研究现状,指出深入研究活火山(包括休眠火山)区的温室气体释放通量与成因对于估算火山来源温室气体的释放规模、建立火山未来喷发预测-预警体系、深入理解岩浆脱气过程与机制等问题均具有至关重要的现实意义和科学价值。Volcanic activities are of great importance to the global deep carbon cycle,which could release large amount of greenhouse gases during both eruptive and quiescent stages,resulting in climatic and environmental changes on local and even global scales. Under the context of global warming,quantitative studies on the contribution of volcanic activities to rising of atmospheric greenhouse gases concentration are critical to discriminating carbon emissions associated with nature and human and to accumulating essential data for geological carbon budget. In this study,we briefly reviewed types,characteristics and research methods of greenhouse gases emissions,and the current status of research on fluxes and origin of greenhouse gases emitting from volcanic fields of China. Based on internationally accepted theory in volcanic-related greenhouse gases,we proposed that,systematic studies on fluxes and origin of greenhouse gases emitting from volcanic activities would contribute to estimating scale of greenhouse gases emissions,volcanic monitoring and magma degassing.
