| 摘 要： | 冯家山灌区是陕西省渭北黄土台塬大型灌区之一 ,在灌溉过程中 ,由于片面提高地表水利用率而忽视地表水、地下水联合开发加之灌溉技术落后等原因 ,在灌区诱发了一些生态环境负效应。在分析灌区环境地质问题的基础上 ,运用地理信息系统 (GIS)技术 ,将GIS与模糊综合评价模型集成 ,对灌区地质环境质量进行评价 ,并针对不同地质环境质量分区探讨了水资源合理开发利用模式

| Abstract: | Fengjiashan Irrigation area is one of the biggest irrigationareas in Wei Bei loess plain of shaanxi province, on account of one-sidedly enhancing surface water's utilization during irrigation, ignoring combinative explore between the surface water and the ground-water and lagging irrigation technology, a lot of negative effects of ecological environment have induced. On the basis of analyzing of the environment-geological problems, and applying of geographic information system technology, integrates GIS and fuzzy comprehensive model, the geological-environment quality of the irrigation area is divided into four types. the modes of rational exploring and utilizing water resources is put forward. |
