In order to study the effects of warming on the decomposition of soil organic carbon (Rh) under Asia monsoon climate and soil properties, we designed a field soil warming experiment for a cultivated Andisol. Raising the soil temperature by 2℃ in the heated plots appeared to increase Rh during the cool seasons (winter to early summer) by approximately 2-13% compared to the non-heated control plots. In contrast, during the warm seasons (summer to Autumn), soil warming induced the decreased Rh in the heated plots, about 10-18% lower relative to the control plots. Our results suggest that 2℃ temperature raise can have drastically different impact on soil organic matter decomposition between warm and cold season most likely through its effect on soil moisture regime, highlighting the importance of accounting for temperature vs. moisture interaction in the models when predicting soil carbon dynamic under climate warming scenario.

为了研究在亚洲季风气候和特性下，变暖对培养的Andisol的变暖经验的影响秋季，土壤变暖诱导了加热地块的降低，相对于对照地块，低约10-18％。 ETS ETS ETS ETS ETS ETS ETS ETS在土壤湿度方面的ETWECT，强调了在模型中预测气候变暖场景下的土壤碳动态时，在模型中考虑了温度与水分相互作用的重要性。
