| 摘 要： | 内蒙古锡盟太仆寺旗天然草地转变为农田后,不同农垦年限下,土壤特性对CH4的吸收有不同的影响。结果表明:天然草地转变为农田后,降低了土壤吸收CH4的能力,CH4的吸收量随开垦年限的增加而逐渐降低,但垦殖20年以上的农田土壤对CH4累积吸收量差异不明显。相关分析表明:土壤有机碳含量、全氮含量是影响土壤CH4吸收的主要因子。

| Abstract: | CH4 Absorption of soil properties from natural grassland in Taipusi County,Inner Mongolia is studied with laboratory incubation method.Findings show that: CH4 absorption was reduced significantly after grassland was changed into cropland;however for croplands over 20 years,it makes little difference.For natural grassland,CH4 absorption of soil decreased respectively.Experimental result and analysis indicate that: soil organic carbon,total nitrogen are main influential factors of CH4 absorption of soil. |
