Overview on the Measurement Techniques for Methane Emission from Ruminants

GAO Zhi-ling et al(College of Resources and Environmental Science,Agricultural University of Hebei,Baoding,Hebei 071000)  
Several commonly used measurement techniques such as mass balance techniques,micrometeorological mass difference techniques and tracer methods were summarized.It was indicated that the accuracies of these techniques were not significant different.However,their flexibilities,representativeness and adaptabilities were much different.For example,mass balance techniques and micrometeorological mass difference were strongly limited due to the alternation of the animal living conditions,difficulty of separating the ruminant methane emissions from the manure,or expensive equipment.The micrometeorological mass difference techniques were limited due to incomplete measurement of gas plumes,overestimation or complex farm situation and wind conditions.Tracer method might be limited in some cases due to the relatively high uncertainty.Among these techniques,inverse dispersion technique and tracer method might have great potential in determining methane emission factors from ruminants due to their great flexibilities,representativeness and wide adaptability.
