The present study aimed to analyze the effects of piling height on greenhouse gas and NH_3 emissions during 41 weeks stacking of dairy manure, and the effects on global warming potential(GWP)and particulate matter 2.5(PM_(2.5))were also investigated. Emissions of CH_4 and N_2O were measured by the static chamber-gas chromatography technique and NH_3 was measured by the venting method. The results showed that CH_4 and N_2O cumulative emissions from manure in stack heights of 50 cm were significantly higher than that of 25 cm. However, the opposite trend was shown for NH_3 emission. Methane was the largest contributor to GWP, accounting for 61.41%~63.97% of the total value, N_2O being the second largest contributor at 32.71%~33.70%, and NH_3 contributing the least, accounting for only 2.33%~ 5.88%. GWP increased as stacking height increased from 25 cm to 50 cm, while PM_(2.5) forming potential decreased significantly. The present study suggested that the choice of manure management measures should be taken into consideration for multiple environmental problems.
