| 摘要: 对黄淮海平原典型集约农区N肥污染地下水的初步调查表明，该区地下水硝酸盐(NO-3)污染较严重，高产农区和高产田块污染程度明显高于中低产区和中低产田块；菜地污染程度较粮田严重；随着施N时间的推移和施用量的增加，地下水中硝态氮具有明显的积累趋势，潜在污染不容忽视；地下水NO-3含量与N肥施用量呈明显正相关关系。 |

| Abstract: Results obtained from investigation at intensive agricultural region in Huanghe-Huaihe-Haihe Plain demonstrate that nitrate pollution of ground water is serious in high-yield agricultural region and in high-yield farmland.Nitric nitrogen content in ground water is higher in vegetable-land than in grain land.Nitrate content in ground water accumulates obviously with the increase of N-fertilizer applied,so the potential pollution should not be ignored.Nitric nitrogen content in ground water has positive relation with the amount of N-fertilizer applied. |
