英文摘要	在规模化猪场内选择垫料育肥猪舍作为试验舍,以传统水泥地面育肥猪舍作为对照,利用多气体分析仪对试验舍和对照舍春夏两个育肥季节的NH_3、CO_2、CH_4和N_2O含量进行了连续3d的监测。结果表明:试验舍 NH_3、CO_2和N_2 O的平均含量分别只有对照舍的40%、70%和77%,存在显著性差异(P＜0.05);夏季由于温度高,垫料易于厌氧发酵,加大了CH_4排放,试验舍CH_4平均含量高于对照舍,但两者之间无显著差异(P= 0.089),春季试验舍的CH_4平均含量低于对照舍,两者之间差异显著(P＜0.05);试验舍中NH_3含量变化在春季和夏季无显著差异(P=0.072),CO_2、CH_4和N_2O则存在显著性差异(P＜0.05),夏季试验舍CO_2含量低于春季,但NH_3、CH_4和N_2O含量高于春季试验舍。说明垫料型猪舍能够改善舍内环境,减少有害气体排放。; To investigate ammonia and greenhouse gas concentration condition in swine barn,a hoop structure barn as experiment barn and typical swine barn with brick-concrete floor as control were chose at a confined swine farm in Beijing,gases concentration were measured for 3 consecutive days during spring and summer seasons using INNOVA 1312 multi-gas monitor. The results showed that the average NH_3,CO_2 and N_2 O concentration in experiment barn was by 40%,70%,77%,respectively,compared with control barn(P＜0.05).The average CH_4 concentration in hoop structure was higher than that in the control barn in summer,but lower in spring.The concentrations of CO_2,CH_4 and N_2 O had significant different(P＜0.05)between summer and spring season in the hoop structure,but NH_3 had no significant different,the CO_2 concentration was lower in summer,NH_3,CH_4,N_2O concentration was higher in summer than that in spring.The hoop structure barn could improve indoor environment and mitigate gases emission.
