摘要:
地下水资源在中国社会经济发展中发挥重要作用,特别是在地表水资源相对匮乏的北方地区。掌握一个地区地下水资源状况、动态变化特征及可开采潜力,对该地区的供水安全保障至关重要。本文选择雄安新区,在近年来开展的区域水文地质调查、监测及综合研究等成果基础上,结合前人研究,对雄安新区区域水文地质条件、地下水动态变化特征等进行分析总结;以恢复地下水降落漏斗为地下水可持续开采利用方案的目标,从白洋淀流域平原区尺度,设置现状开采条件、河流补水、工农业节水及地下水禁(限)采等不同情景方案,采用地下水数值模拟技术,综合分析不同情景30年后的预测结果,提出白洋淀流域平原区地下水可持续开采利用方案;在流域地下水可持续开采利用方案基础上,分析雄安新区地下水可开采的最大资源量,进而评价雄安新区地下水可开采潜力。结果显示,雄安新区区域水文地质条件相对简单,浅层富水性中等,深层富水性较强;地下水位为多年下降状态,近年来,浅、深层地下水整体呈企稳或回升状态,局部地区仍有所下降;地下水质量总体良好,且较为稳定。根据评价结果,雄安新区地下水可开采潜力约为1.80×108 m3/a,其中,浅层地下水可开采潜力约为1.50×108 m3/a,深层地下水可开采潜力约为0.30×108 m3/a。

Abstract:
Groundwater resources have played an important role in the national social and economic development, especially in the northern region where surface water resources are relatively scarce. It is very important for security guarantee of water supply to understand hydrogeology, dynamic characteristics of groundwater, and exploitation potential of groundwater resources in a certain area. The Xiong'an New Area was selected as pilot area to analyze and summarize the regional hydrogeology and dynamic characteristics of groundwater based on hydrogeological survey and groundwater monitoring in recent years as well as the previous achievements. Aiming at recovering groundwater depression cones as the sustainable exploitation strategy of groundwater, different scenarios were put forward, including current condition, river recharge, water-saving from agricultural and industrial water consumption, and decrease or prohibition of groundwater pumping. Using groundwater numerical simulation technology, the prediction results of different scenarios after 30 years were comprehensively analyzed, and the sustainable exploitation and utilization scheme of groundwater in plain area of Baiyangdian Watershed was put forward. The results show that the hydrogeology is relatively simple in Xiong'an New Area with normal water-bearing capacity in shallow aquifers and good in deep aquifers. The groundwater level has been declining for many years, and getting stable or rising up in the past one or two years. The quality of groundwater is good and stable both in shallow and deep aquifers. According the assessment, the exploitation potential of groundwater in Xiong'an New Area is about 1.80×108 m3/a, with 1.50×108 m3/a in shallow aquifers and 0.30×108 m3/a in deep aquifers.
