| 摘要: |
| 针对华北平原农业灌溉地下水超采的问题，以房山节水示范区为例，采用机井取水量定额管理的方法，基于水文地质模型软件GMS，对示范区地下水位进行模拟研究。结果表明：取水量定额管理后，示范区2020年模拟的地下水位比现状回升了3.34 m，比按现状取水量模拟的地下水位多回升了1.49 m。机井取水量定额管理可以提高地下水位的回升力度，是实现区域地下水采补平衡的有效措施。 |

| Abstract: |
| Aiming at the problem of groundwater overexploitation in North China Plain, a case of water-saving demonstration area in Fangshan, where the situation of groundwater overexploitation is serious, is investigated using the method of the water supply quota management of well. A groundwater simulation software GMS was used to simulate groundwater in water-saving demonstration area. The results showed that:After the water supply quota management, the simulated groundwater level in the demonstration area in 2020 would be recovered to 3.34 m, which is 1.49 m higher than the current management simulated groundwater level. Quota management can improve the strength of underground water level recovery and is one of the effective measures of groundwater dynamic balance. |
