| 摘要: |
| 分析了地下水相关定义及影响因素,通过试验区的布置对地下水位及水质进行观测,在一次灌水期间连续的30天左右时间内,地下水水位及水质随着灌溉时间呈现出一定的变化规律,灌区地下水中硝态氮的长期积累将会对灌区环境造成威胁,地下水位的上升可能导致盐碱地的发生,灌区应建立优化灌溉制度,通过技术及管理措施等减少地下水中硝酸盐含量。 |

| Abstract: |
| It analyzed the definition and influencing factors of groundwater, Through the layout of the experimental district can observe the underground water level and water quality, About 30 consecutive days in an irrigation period, it change with irrigation time on the groundwater level and water quality, the nitrate nitrogen will threaten the environment of irrigated district in groundwater on the long-term . it can lead to the occurrence of saline and alkaline lands when the rise of the water level, irrigation district should establish the optimized irrigation and through technical and management measures to reduce nitrate content in groundwater |
| Key words: groundwater; Shijin irrigation district; nitrate content |
