中文摘要	在甘肃省石羊河绿洲灌区连续4 a冬小麦保护性耕作田间定位试验的基础上,用静态箱-气相色谱法研究了5种耕作措施下,冬小麦田从前季灌浆期到后季分蘖期期间CO_2排放通量的变化规律.结果表明:不同耕作措施下,CO_2排放通量在观测期内呈现"高-低-高"的双峰型变化曲线;秸秆翻压处理CO_2排放通量最高,传统耕作CO_2排放通量介于免耕不覆盖处理和秸秆翻压处理之间;传统耕作与免耕不覆盖两处理CO_2排放通量间差异性显著;CO_2排放通量与耕层(0～30 cm)土壤温度和土壤含水量呈显著正相关,其中土壤含水量对CO_2排放通量的影响大于土壤温度对其的影响.
英文摘要	Based on the four years field experiment on winter wheat with different tillage measures in Hexi Oasis Irrigation Area, the variations of CO_2 emission flux form five winter wheat fields under different tillage measures during former filling stage to later tillering stage were measured by static chamber-gas chromatographic techniques. The results were as follows: during observation period, the CO_2 emission flux under different tillage measures showed bimodal curve; the CO_2 emission flux of conventional tillage with stubble incorporated(TIS) was higher than any other treatments;the CO_2 emission flux of conventional tillage(T)was lower than that of conventional tillage with stubble incorporated(TIS),but higher than that of no-tillage without stubble retention(NT), significant differences of CO_2 emission flux were found between the conventional tillage(T)and no-tillage without stubble retention(NT); the CO_2 emission flux in the 0～30 cm soil layer was significantly correlated to the soil moisture and soil temperature.
