草原土壤

放牧行为改变了土壤结构，有利于土壤微生物反硝化作用的发生，在一定程度上降低了草原土壤N2O的排放。

Results suggested that grazing behavior altered the soil structure which were benefit to microbiological denitrification so that N 2O emission from this steppe soil was reduced .

典型草原土壤全N、速效N和速效P含量以及速效P/全P和C/N比值低于高山草原，但速效N/全N比值和全P含量高于后者。

The total and available nitrogen , available phosphorus and the ratio of available phosphorus to total phosphorus and of organic carbon to nitrogen were all higher in alpine grassland than in arid grassland .

由于自养硝化作用在不同季节的发生，使得草甸草原土壤N2O的产生潜势也高、低起伏变化。

The increasing and decreasing of N2O production potential result from the appearance of autotrophic nitrification in different growing period .

实验结果表明：内蒙古温带草甸草原土壤N2O产生过程以硝化作用为主。

The research results showed that the heterotrophic nitrification is the important microbiological process of N2O production in this kind soil .

从而揭示了内蒙古温带草原土壤以异养硝化作用过程为主产生N2O和N2O排放通量较低的微生物学机理。

Thereby , the N2O emission flux from temperate grassland soils was lower because that the heterotrophic nitrification is key N2O production process in these soils .

以大量的室内模拟培养实验，以内蒙古温带草甸草原土壤为研究对象，利用AIM乙炔抑制法，模拟野外条件对原样土壤样品进行N2O产生过程进行研究。

In this paper , A lots of laboratory experiments using the acetylene inhibition method ( AIM ) were carried to investigate the N2O production processes in chernozem soil of meadow grassland in Inner Mongolia .
