| 摘 要： | 以江西千烟洲农业生态系统内水稻田为对象,通过对不同深度土壤水中铁锰含量与三氮含量的相关分析,确定了包气带中影响三氮迁移转化的主要铁锰浓度场位。分析结果表明:120 cm以下深度铁锰含量呈显著性正相关,铁锰的伴随关系良好;在120 cm土层中三氮变化受铁锰浓度场的控制显著,其他土层并不明显;五个不同深度土层中铁锰与氨氮和硝酸盐氮的相关系数出现波浪形变化,并且在研究区域,铁锰均表现出对硝化反应的抑制作用。 |
| 关 键 词： | 铁锰 氮 迁移转化 相关分析 |

| Abstract: | Taking agri-ecosystems paddy field in Qianyanzhou,Jiangxi for example,the paper analyzed the relations between iron,manganese and nitrogen contents at different soil depths to determine the position where iron and manganese affected nitrogen transport and transformation in unsaturated zone.The results showed that the iron and manganese content had a significant positive relationship underneath 120cm.Nitrogen transport and transformation are affected obviously at the same depth,while not in other depths.The correlation coefficient between iron,manganese and nitrogen varies in wave among five different depths.Both iron and manganese have a negative effect on nitration in the scope of the study. |
| Keywords: | iron and manganese nitrogen migrate and transform correlation analysis |
