| 研究以清远市针叶林为研究对象，测定其土壤全氮含量，并用空间插值法分析其含量分布状
况。结果显示：清远市针叶林土壤同一土层不同区域为中部土壤全氮含量最高，西北部和东南部针叶
林土壤全氮含量较低；不同土层全氮含量不同，随着土层厚度的增加，全氮含量不断减小；0~20 cm、
20~40 cm、40~60 cm 土层土壤全氮处于Ⅲ级水平，60~80 cm 土层土壤全氮处于Ⅴ级水平。 |

| Abstract: |
| This study took coniferous forest in Qingyuan city as the research object, the content of soil total
nitrogen was measured and its distribution was analyzed by spatial interpolation method. The results showed that
the soil total nitrogen content in different regions of the same soil layer of coniferous forest in Qingyuan city was
the highest in the central coniferous forest, while the soil total nitrogen content in the northwest and southeast
coniferous forest was relatively low. The total nitrogen content in different soil layers was different, and the total
nitrogen content decreased with the increase of soil thickness. The soil total nitrogen in the 0-20 cm, 20-40 cm and
40-60 cm soil layers was at the high level of Ⅲ , and the soil total nitrogen in the 60-80 cm soil layer was at the
low level of Ⅴ . |
