Statistic analysis showed that soil temperature as the driving factor to the diurnal variation of soil respiration. Soil temperature and soil moisture were the dominant environmental factors affecting the seasonal variation of soil respiration and explained 87% of its variability. LAI and root biomass were positively related to soil respiration rate, indicating that biotic factors also affected the seasonal variation of soil respiration. However, soil properties such as soil organic content, total nitrogen content, and C/N ratio had poor correlations with soil respiration. Top-dressing nitrogen fertilizer increased soil respiration significantly.

统计分析表明：土壤温度是玉米生态系统土壤呼吸日变化的驱动因素；土壤温度和土壤水分是影响土壤呼吸季节变化的关键因素，二者可以解释玉米生长季土壤呼吸时间变异的87%；LAI和根系生物量与土壤呼吸速率呈正相关，说明生物因子对土壤呼吸季节变化也有影响；土壤有机质、全氮和碳氮比等土壤理化特性与土壤呼吸速率的关系较弱；玉米生长季追施氮肥明显促进土壤呼吸速率。
