在陆地生态系统中，土壤呼吸是最大的碳通量组成部分之一。我们讨论了控制土壤呼吸的因素，同时集中在高山实验场进行的研究。土壤呼吸受土壤温度、土壤湿度、降雨事件、台风和根系呼吸的影响。我们认为，在高山实验场的土壤呼吸的时间和空间变异性和审查的变化，每年在日本森林土壤呼吸。在26项汇编的研究中，年土壤呼吸值范围为203至1，290 g C m− 2年−1，平均值为669 g C m− 2年−1（SD=264，CV=40）。我们注意到，需要更多的研究和数据合成的土壤呼吸和土壤碳动态在日本森林的准确预测。最后，比较了几种土壤呼吸速率的测量方法，并讨论了土壤呼吸速率对全球气候变化的意义。
Within terrestrial ecosystems, soil respiration is one of the largest carbon flux components. We discuss the factors controlling soil respiration, while focusing on research conducted at the Takayama Experimental Site. Soil respiration was affected by soil temperature, soil moisture, rainfall events, typhoons, and root respiration. We consider the temporal and spatial variability of soil respiration at the Takayama Experimental Site and review the variability of annual soil respiration in Japanese forests. In the 26 compiled studies, the values of annual soil respiration ranged from 203 to 1,290 g C m−2year−1, with a mean value of 669 g C m−2year−1(SD=264, CV=40). We note the need for more studies and data synthesis for the accurate prediction of soil respiration and soil carbon dynamics in Japanese forests. Finally, several methods for measuring soil respiration rates are compared and the implications of soil respiration rates for global climate change are discussed.
