| 摘 要： | 本文根据华北平原地质和水文地质条件，对可调蓄地层、调蓄空间、调蓄水源以及调蓄有利地带进行了系统分析。在此基础上，计算出华北平原地下水最大可调蓄空间为1478.05×108m3，现状地下水位埋深条件下的可调蓄空间为326.29×108m3。制定了地下水调蓄有利地带的选取原则，华北平原地下水调蓄的最好地带是山前冲洪积扇和中东部平原的古河道带。本文在山前冲积扇地带选择了7处地下水调蓄有利地带进行专门研究，提出了各调蓄有利地带调蓄空间、调蓄水源以及调蓄方式。7处调蓄有利地带利用当地水源调蓄方案实施后，地下水可增加补给量为16.68×108m3/d。运用地下水数值模拟方法对3处有利地带的调蓄效果进行了模拟分析，结果表明地下水调蓄方案实施后对地下水供水环境的恢复效果十分明显。 |

| Abstract: | According to the geological and hydrogeological conditions in the North China Plain, this paper systematically analyzed the strata, storage space, water source and advantageous areas for adjusting groundwater storage. The alluvial-pluvial fans and ancient stream channels are the advantageous areas for adjusting groundwater storage, whose space has been calculated. The maximum space for adjusting groundwater storage in the North China Plain is 1478.05×108m3, 70% of which is in alluvial-pluvial fan areas, while the rest 30% is in ancient stream channel areas. Judging from present condition of groundwater level, the space for adjusting groundwater storage is 326.29×108m3, 88% of which is in alluvial-pluvial fan areas, and the rest 12% is in ancient stream channel area. In this paper, we selected 7 advantageous areas, which were Chaobaihe alluvial-pluvial fan, Yongdinghe alluvial-pluvial fan, Tanghe-Dashahe alluvial-pluvial fan, Hutuohe alluvial-pluvial fan, Shahe-Minghe alluvial-pluvial fan, Anyanghe alluvial-pluvial fan and Yuhe-Huangshuihe alluvial-pluvial fan. The space for adjusting groundwater storage in these areas was calculated and the water sources and methods of adjusting groundwater storage were discussed. The total space for adjusting groundwater storage was 45.9×108m3. This paper advanced two projects for adjusting groundwater storage: the first project was the artificial recharge of groundwater by using local water resources, and the second project is the internal adjustment of groundwater systems by decreasing groundwater exploitation after implementing South-to-North Water Transfer Project. If the first project of adjusting groundwater storage is implemented in the 7 advantageous areas, groundwater recharge yield would increase 12.37×108m3/d. The effects of adjusting groundwater storage in Chaobaihe alluvial-pluvial fan, Yongdinghe alluvial-pluvial fan and Hutuohe alluvial-pluvial fan were estimated with the method of groundwater numerical analog. The results showed that groundwater environment would be remarkably improved after actualizing the projects of adjusting groundwater storage. |
