摘要
陕北风沙滩地区地处干旱半干旱地区,矿产资源丰富,生态环境脆弱。地下水是区域内生产生活用水的主要来源,同时也是控制区内生态环境演化的重要因子。在查明该区域地下水补径排条件与生态环境关系的基础上,应用地下水流数值模拟技术,以地下水开发-生态环境响应-地下水调控为主线,分析了地下水开发方案下的生态环境响应,确定了区域地下水开发的合理阈限,为区域地下水开发利用与生态环境的良性发展提供技术支撑。
The wind-blown sand area of northern Shaanxi lies in an arid and semi-arid area, where mineral resources are abundant and the eco-environment is vulnerable. Groundwater is not only the main source of water for production and living uses, but also the key factor of maintaining the regional eco-environmental evolution. The authors made clear the relation between the groundwater recharge and discharge conditions and eco-environment and then analyzed the eco-environmental response in the groundwater exploiration plan by using the groundwater flow numerical simulation technology and raking the groundwater exploitation-eco-environmental response-groundwater regulation and control as the main line. Finally, they determined the rational threshold limit values for groundwater exploitation. A technological support was provided for the groundwater exploitation and utilization and environmental improvement.
