In order to reveal the impact on greenhouse gas emission in different modes of sheep manure composting, the greenhouse gases(GHGs) emission rules and global warming potential(GWP) of five intact composting treatments, such as pure sheep manure(Y), sheep manure and wheat straw(YC), sheep manure and soil (YT),sheep manure,wheat straw and soil (YTC),sheep manure,cattle manure and wheat straw(YNC),were studied by using the static chamber gas chromatography techniques. The results showed that compost temperature and air temperature in greenhouse both took on a descending-rising trend during composting period. Adding wheat straw could increase the compost temperature. However, adding soil could decrease the compost temperature. The emission flux of CO_2,CH_4,a nd N_2O under each treatment took on an ascending-descending-being stable trend during the whole composting period. The maximum emission flux appeared on 15 d or so after composting. Moreover, the total emission flux of N_2O, CH_4 and CO_2 decreased respectively in the sequence of YT > Y > YNC > YC > YTC,Y > YNC > YT > YTC > YC and YC > YNC > Y > YT > YCT. The emission flux of CO_2,CH_4 and N_2O was positively correlated with the compost temperature to different extent. The contribution to GWP got lower in sequence of YT > YTC > Y > YC > YNC. YT was recommended to apply based on the GHGs emission amount and realistic compost constituent.
