The situ observation was conducted by using the static chamber-gas Chromatograph technique to observe the soil CO_2 and CH_4 emissions under drip irrigation and furrow irrigation. The results showed that,during the growing seasons in 2012 and 2013,soil CO_2 and CH_4 emissions were significantly affected by different irrigation methods in the vineyard. Compared to furrow irrigation, the annual CO_2 and CH_4 emissions reductions under drip irrigation reached (3 530.341611.97) kg/(hm~2 ? a) and (0.3920.424) kg/(hm~2 ? a)in 2012,and (2 198?43713? 97)kg/(hm~2 ? a) and (0.1360? 192)kg/(hm~2 ? a) in 2013;The differences between the CO_2 emissions under different irrigation treatments were both significant (p< 0.05) in 2012 and 2013. If modifying all the existing furrow irrigation vineyards to drip irrigation vineyards in Ningxia,the Global Warming Potential (GWP)reduction amounts of CO_2 and CH_4 emissions could be estimated as about 70 771 400 kg CO_2 equivalent in 2012 and 44 025 800 kg CO_2 equivalent in 2013 respectively. Thus, drip irrigation system which can effectively inhibit the purge losses of CO_2 and CH_4 emission from soil is an irrigation method and has greater reduction potential for emissions of CO_2 and CH_4.
