提出了温带通气土壤中甲烷浓度的准连续观测。进入土壤的甲烷通量是根据土壤表面的浓度梯度计算的。根据个别地点土壤空气中甲烷的渗透性，在温带森林土壤中观察到年平均吸收率在 0.09 至 1.3 g CH 4 m -2 yr -1 之间。从大气到土壤的甲烷通量季节性较弱，夏季吸收率比冬季高约 50%。这表明进入土壤的甲烷通量主要受土壤中的传输阻力控制，而不是受潜在的微生物分解速率控制。 DOI：10.1034/j.1600-0889.1990.00002.x
Quasi-continuous observations of the methane concentration in aerated soils of the temperate zone are presented. The flux of methane into the soil is calculated from the concentration gradient at the soil surface. Depending on the permeability of methane in soil air at an individual site, yearly mean uptake rates between 0.09 and 1.3 g CH 4 m -2 yr -1 have been observed in temperate forest soils. The methane flux from the atmosphere into the soil shows only a weak seasonality with an about 50% higher uptake rate in the summer than in the winter months. This indicates that the methane flux into the soil is mainly controlled by the transport resistance in the soil rather than by the potential microbial decomposition rate.
