| 摘 要： | 本研究首次以我国内蒙古典型草原生态系统为研究对象，以密闭箱法对土壤－植物系统与大气间Ｎ２Ｏ和ＣＨ４气体交换进行了原位观测研究，通过结合实验室模拟实验研究表明，土壤含水量和温度对草原土壤－植物系统温室气体（Ｎ２Ｏ和ＣＨ４）排放通量有着重要的影响。在一定范围内，土壤含水量增加促进草原生态系统Ｎ２Ｏ排放和ＣＨ４吸收作用。温度升高促进草原生态系统Ｎ２Ｏ排放，但对ＣＨ４吸收的影响作用不明显。

| Abstract: | Using the closed chamber technique, the in situ measurements of N 2 O and CH 4 fluxes from temperate typical nature grassland soil-plant system was firstly conducted in the Inner Mongolia The effect of soil moisture and temperature was studied in the lab The results showed a great effect of soil moisture and temperature on N 2 O and CH 4 fluxes from grassland ecosystem To some extent, the increasing of soil moisture and temperature will improve N 2 O emission In the meantime, with the increasing of soil moisture, CH 4 consumption will be improved, but there is no significant relationship between temperature increasing and CH 4 absorbing |
