摘　　要：土壤呼吸是土壤圈与大气圈碳交换的重要环节,其动态变化直接影响全球碳循环过程。近年来,土壤呼吸对全球变化的响应和适应规律成为学界关注的热点问题。本研究综合论述了近几十年国内外关于增温、CO2浓度升高、氮沉降、降雨格局改变(干旱和增雨)等全球变化因子对土壤呼吸影响的研究进展,系统探讨了全球变化对陆地生态系统土壤呼吸的影响过程及其调控机制。气候、生物和土壤因素在不同研究尺度上对土壤呼吸调控差异是造成当前全球变化对土壤呼吸差异性(正效应、负效应和无影响)影响的主要原因。基于目前的研究现状,探讨了当前在全球变化对土壤呼吸影响研究过程中存在的一些问题,并据此讨论了未来针对这些问题的具体解决措施和发展方向。Soil respiration,as the major pathways of carbon exchange between pedosphere and atmosphere,directly affect the process of global carbon cycle. In recent years,the response and adaption mechanism of soil respiration to global change have became a hot spot. This paper reviewed the research progress about the effects of global change on soil respiration over the past few decades in China and abroad,such as climate warming,N deposition,high CO2 concentration and changes in global rainfall pattern（drought and increased rainfall）,focusing on the process and regulating mechanism.The divergences in the impact of global change on soil respiration were mainly caused by regulated distinctions of soil respiration from climate,biological and soil factors at different studied scales,which contain positive,negative or neutral effects. Based on current researches,by discussing some existingproblems in the study of effect of global change on soil respiration,we put forward the specific approaches and future developmental direction.
