英文摘要	在北京选择一典型猪场，对不同季节育肥舍的氨气浓度进行了为期1年的试验测定，2004-2005年试验期间每2个月测定1次，每次测定3-4d，每2h采样一次，并根据二氧化碳平衡原理，对猪场不同生长阶段的育肥猪氨气排放通量进行了估算。结果表明，2005年1月舍内氨气的平均浓度为（10．09±4．60）mg·m^-3。2004年7月舍内氨气平均浓度为（3．44±2．34）mg·m^-3，5月舍内氨气浓度为（6．29±4．07）mg·m^-3，11月舍内氨气浓度为（6．98±2．63）mg·m^-3，夏季舍内氨气浓度日夜变化不显著，冬季每日最低氨气浓度出现在9：00-17：00时段；育肥猪饲养期间的氨气排放通量为每头107．18—424．42mg·h^-1。; Ammonia concentration in animal housing facilities has been one of the high concerns because of its significant effects on human health, animal behavior and the environment. To investigate NH3 emissions flux from finishing pigs, ammonia concentration measurements were taken from pig farm houses for one year. Every two months, each collection data of 72-80 h were scheduled in 2004-2005. The results indicated that NH3 emission was strongly related to temperature and seasonal variation. The NH3 emission flux per pig was estimated based on ventilation rates calculated by application of carbon dioxide mass balance method. The NH3 concentration and emission flux varied diurnally and seasonally. The concentrations of NH3 averaged （10.09±4.60）mg·m^-3 in January, （3.44±2.34）mg·m^-3 in July, （6.29±4.07）mg·m^-3 in May and （6.98±2.63）mg·m^-3 in November, respectively. The concentrations of NH3 were lower between 9：00 am-17：00 pm during winter season, which greatly related to temperature and ventilation rate. NH3 emission flux from pig house varied between 107.18-424.42 mg·h^-1 per pig.
