中文摘要	文中通过静态箱采样,利用TurboMatrix 100型热解析仪与气相色谱联用法,分析了环境因子,如水分、温度、光照和玉米秸秆添加等对绿洲干旱区土壤羰基硫(COS)和二硫化碳(CS_2)交换通量的影响。结果表明:干旱土壤COS和CS_2的平均通量分别为1.17、3.28pmol·m~(- 2)·s~(- 1),淹水土壤COS和CS_2的平均通量分别为- 11.11、- 3.41pmol·m~(- 2)·s~(- 1),干旱土壤作为COS和CS_2的源,淹水土壤则为其汇,且淹水土壤交换强度高于干旱土壤。与淹水土壤相比,玉米秸秆的添加使得COS和CS_2的交换强度分别提高了34.2%和149.27%。同时测得COS具有明显的日变化规律,干旱土壤总交换量基本平衡,表现为微弱的释放,淹水土壤总体表现为较强的吸收。CS_2则表现不明显。水分和温度虽然与交换通量之间没有显著相关性,但对交换方向和强度有重要影响。对以上过程的讨论提示我们非生物产生和消耗过程存在的可能性。
英文摘要	A static chamber enclosure method was used to determine the role of Oasis soil in arid area in carbonyl sulfide(COS) and carbon disulfide(CS_2 ) exchange with the atmosphere. The influence of several environmental factors,such as soil,moisture,light and corn straw adding on the exchange fluxes was studied by laboratory culture experiment. Results showed that dry soil acted as the source with the averages of COS and CS_2 fluxes were 1.17 and 3.28pmol·m~(- 2)·s~(- 1),respectively. The flooded soil was the active sink for COS and CS_2,with the averages were - 11.11 and - 3.41 pmol·m~(- 2)·s~(- 1),respectively. Exchange of COS and CS_2 in flooded soil was stimulated after addition of corn straws,which were 34.2% and 149.27% more rapidly than the control. COS exchange fluxes showed a distinct diurnal variation. Release and uptake of COS were nearly balanced in dry soil,with weakly emission of 0.23pmol·m~(- 2)·s~(- 1). While COS uptake was obviously observed in flooded soil. CS_2 exchange rates didn’t change significantly with the diurnal. Soil moisure or temperature showed no significant correlation with the exchange fluxes,but revealed the important impact on the intensity and direction of exchange fluxes. The aboved discuss hinted us the possibility of abiotic production and consumption process presence.
