| 中文摘要: |
| 对1982—2009年宝鸡峡-羊毛湾灌区的地下水的水化学特征、水位动态和水化学动态进行分析和水质调查，采用Pearson指数法和逐步回归方法对地下水的矿化度与离子构成关系进行
相关分析，以揭示灌溉、黄土塬灌区外源引水、地下水开采与农业生产活动对地下水的水化学类型和水位、水质动态的影响及其演变规律。结果表明：地下水的矿化度变化主要受阴离
子（HCO3-、SO42-、Cl-）控制，Cr(Ⅵ)和NO-3-N是灌区地下水的主要污染威胁。同时，针对灌区面临的水资源和水环境问题，提出了水资源与农业生态环境的保育措施，可为黄土塬灌区地下水资源的利用与保护提供借鉴。 |

| Based on the data of 1982—2009, we analyzed the chemical characteristics, dynamic of water level and water chemical properties of groundwater and investigated the water quality in Baoyang Irrigation District. Using Pearson index law and Stepwise regression analysis, we also analyzed the correlation between the groundwater salinity degree and ion composition, so as to reveal the effects of irrigation, external water diversion, groundwater exploitation and agricultural production activities on the groundwater water chemical type, water level and water qua
lity dynamic in the loess tableland irrigation district. The results show that the groundwater salinity degree changes are mainly controlled by anions (HCO3-, SO42-, Cl-), and Cr (VI) and NO-3-N are the main threat of pollution to groundwater. Facing the problems of water resources and water environment in the district, we proposed some countermeasures for the conservation of water resources and ecological environment which may be used as reference to the protection and utilization of groundwater resources of loess tableland irrigation districts. |
