摘　　要：土壤呼吸是当前碳循环研究领域中的一个引人关注的热点问题,也是陆地生态系统向大气释放CO2最大的源,具有多方面的生态意义。综合评述了国内外有关土壤呼吸研究成果与测定方法,阐述了影响土壤呼吸的主要因素分别有温度、湿度、植被类型、土壤理化性质和人类活动等,概括了土壤呼吸及其各分量的不同测定方法及特点,并讨论了土壤呼吸今后的努力方向。Soil carbon plays an important role in global carbon cycle. Soil respiration is hot topic in the area of carbon cycle research. It has become the largest source that terrestrial ecosystems releases CO2 to atmosphere, and is also an index for many functional processes of ecosystems. Based on the research on soil respiration of other scholars, factors having an effect on soil respiration are temperature, humidity, the types of community, physical and chemical property of soil, etc, respectively. Some methods of measuring soil respiration and its characteristic were introduced. Finally, the paper made a summary of achievements on soil respiration in the world and suggested emphases of further study in this field.
