以孝义市克俄工矿复垦区田间定位试验为基础，于2010年5月至2011年11月利用LI-8100测定了不同施肥处理试验区玉米田土壤呼吸的季节动态变化，分析不同施肥处理土壤呼吸对土壤温度的敏感性。结果表明：不同施肥处理下，2011年试验区玉米农田土壤碳通量均高于2010年；并且随着玉米生长期的不同，土壤碳通量也发生相应的变化，尤其在玉米出苗、抽穗、灌浆期不同施肥处理间差异显著；不同施肥处理下土壤呼吸对土壤温度的敏感度Q10值也存在明显差异，表现为CK＜无机肥＜有机肥＋无机肥＜有机肥。

Based on the location experiment in the mining reclamation area of ke′e in Xiaoyi City ,the seasonal dynamic changes of soil respiration was determined by using LI-8100 of the corn field under the different fertilizer practice experimental from May ,2010 to November 2011 , soil respiration to the soil temperature sensitivity was analyzed under the different fertilizer measures. The results indicated that soil carbon flux in 2011 was higher than that in 2010 under the different fertilizer practice;soil carbon flux also changed during the different period of the corn growing , especially in the corn seedling stage ,heading stage and filling stage under different fertilizer processing;in the same time ,Q10 value which was the soil temperature sensitivity of the soil respiration varies significantly affected by different fertilization ,Its performance was CK<inorganic<organic+inorganic<organic.
