| 摘要: |
| 分析土壤小样本的结果表明,无机氮在根层土壤剖面上是不均匀分布的。这种垂直的空间变异不仅适用于铵态氮,也适用于硝态氮。氮矿化势在根层土壤剖面上的空间变异反映出土壤中有氮素转化的某些热点的存在。 |

| Spatial Variation of Mineral Nitrogen and Nitrogen Moneralization/Immobilization Potential in Soil Profile of Root Layer |
|

|
| Abstract: |
| The distribution of mineral nitrogen and nitrogen mineralization/immobilization potential in soil profile of the upper root layer were investigated by taking small soil samples.The investigation showed that neither ammonium nor nitrate did evenly distribute along the profile.The spatial variation of nitrogen mineralization/immobilization potential in the soil profile indicated that there were somehot spotsregarding nitrogen turnover in soil. |
| Key words: Mineral nitrogen nitrogen mineralization/immobilization potential soil profile root layer spatial variation |
