摘要

［目的］分析不同土壤水分变化及干湿交替对土壤CO

排放的影响，为绿洲农田土壤碳循环提供科学依据。［方法］选取新疆绿洲棉田土壤，通过室内控制模拟试验，以及用气相色谱仪分析CO

浓度。［结果］（1）与60%WFPS（土壤充水孔隙度）相比，40%WFPS对土壤CO

排放起到了显著的抑制作用（p

0.05），而80%WFPS对土壤CO

排放无显著性影响（p

0.05）。培养结束时，与60%WFPS的土壤CO

累积排放量相比，40%WFPS的土壤CO

累积排放量降低26%（p

0.05），而80%WFPS的土壤CO

累积排放量仅增加0.04%（p>0.05）。（2）多次干湿交替循环后，干湿交替处理下的土壤CO

累积排放量显著低于恒湿处理。在不同干旱强度处理中，重度干旱（SD）处理对土壤CO

排放速率响应程度大于适度干旱（MD）处理，但多次干湿交替循环后，SD处理下的土壤CO

累积排放量却显著小于MD处理。随干湿交替循环次数的增加，干湿交替对土壤CO

排放速率的影响显著降低，特别是对土壤CO

排放速率最高值的影响最大。［结论］在新疆绿洲棉田土壤中，干湿交替能降低土壤CO

排放量，降低量随干旱强度的增大而增大。

Abstract

[Objective] To evaluate the effects of soil water change and alternate drying and wetting on soil CO2 emissions in order to provide basis for soil carbon cycle in oasis farmland.[Methods] Soil samples were taken from oasis farmland in Xinjiang region

which was used for incubation experiment in laboratory. CO2 concentration was analyzed by meteorological chromatograph.[Results] (1) Compared with 60% WFPS(water filling soil porosity)

40% WFPS had a significant inhibiting effect on soil CO2 emissions(p<0.05)

while 80% WFPS was no significant influence on soil CO2 emissions(p<0.05). At the end of the experiment

compared with 60% WFPS

accumulation of soil CO2 emissions of 40% WFPS was reduced by 26%(p<0.05)

while accumulation of soil CO2 emissions of 80% WFPS was increased by 0.04%(p>0.05). (2) After multiple wet dry cycling

soil CO2 accumulative emissions under alternate drying and wetting condition was significant lower than that of constant moisture treatment(p<0.05). Under different drought intensity

the effect of severe drought on soil CO2 emission rate was higher than that of the moderate drought. But after multiple wet dry cycling

the effect of severe drought on the accumulation of soil CO2 emissions was lower than that of moderate drought(p<0.05). With the increased of drying and wetting alternation

the effects on soil CO2 emission rate was reduced significantly

especially for maximum soil CO2 emission rate.[Conclusion] Drying and wetting alternation can reduce soil CO2 emissions

and the amount of reduction increases with the increasing of drought intensity in Xinjiang oasis soil.
