The static chamber /gas chromatograph techniques and LI-8100A portable CO_2 analyzer were applied to observe continuously the emission flux of greenhouse gases emission from soils under the different tillage measures from the very start of 2017 to October. The results showed that,the soils with different tillage measures were the CH_4 sink. The fluctuation range of the absorbed flux was 0.010-0.080mg·m~(-2)·h~(-1). The soils with different tillage measures were the source of CO_2 emission; the fluctuation range of the the emission flux was 0.04-0.27mumol·m~(-2)·s~(-1). The soil CH_4 absorbtion flux was significantly and positively correlated with soil water content and significantly negatively correlated with soil temperature. CO_2 emission flux was significantly negatively correlated with soil water content and significantly and positively correlated with soil temperature. The traditional tillage got the maximum annual CO_2 and CH_4 comprehensive GWP among all the measures as 1586.24kg ( CO_2 ) · hm~(-2). The integrated GWP ranking of each treatment is: T >TS >NTS >NT. But there was no significant difference between NT and NTS. Therefore,no-till treatment had the greenhouse gas reduction effect.
