中文摘要:
      研究白洋淀对区域地下水的补给量,对雄安新区生态水城的建设具有重要意义。目前对湖水与地下水补给量的计算,主要基于同位素测试以及水位和水温长序列监测等方法,具有较高的计算成本和局限性。以人工甜味剂为示踪剂,在查明安赛蜜、三氯蔗糖、糖精、甜蜜素4种典型人工甜味剂在白洋淀和浅层地下水空间分布的基础上,通过构建白洋淀的金龙淀内安赛蜜时序特征,结合淀内补排特征和气象监测数据,厘清金龙淀对地下水的补给量。计算结果显示:4种人工甜味剂在地下水中的平均浓度分别为0.11、0.14、0.04、0.05 μg/L,在白洋淀内的平均浓度为1.16、2.17、0.21、0.38 μg/L。金龙淀内安赛蜜浓度在监测时间段内介于0.73~1.31 μg/L,其向地下水的渗漏率为0.75×104 m3/d,年渗漏量为273.75×104 m3。研究结果表明:在研究区南部和白洋淀内水环境受人类活动干扰最为严重,在后期的水生态环境保护和治理中需对该区域进行重点研究;白洋淀是雄安新区地下水主要补给来源,其对区域地下水量和水质均有重要影响,精确刻画白洋淀与地下水的交互补给作用,能够为雄安新区水资源的科学调控提供重要支撑。
英文摘要:
      Clarifying the infiltration volume of the Baiyangdian Lake to the groundwater is crucial to the establishment of ecology-water city in Xiongan New Area. Currently, the isotope test, long time series monitoring of water table and water temperature are used to calculate the recharge volume of the lake to the groundwater. However, these methods are costly and have certain limitations. Here, we used four representative artificial sweeteners (AS) as anthropogenic tracers, namely acesulfame (ACE), sucralose (SUC), saccharin (SAC) and cyclamate (CYC), the spatial distribution of which in surface water and shallow groundwater were described, and then the time series of ACE in the Jinlongdian Lake were used to calculate the lake’s recharge volume to the groundwater considering its recharge and discharge characteristics and the climate monitoring data. The average contents of ACE, SUC, SAC, and CYC in the groundwater were 0.11, 0.14, 0.04, 0.05 μg/L respectively, whereas those in Baiyangdian Lake were 1.16, 2.17, 0.21, 0.38 μg/L respectively. The concentrations of ACE were in the range of 0.73-1.31 μg/L in the Jinlongdian Lake during the monitoring time, and its recharge volume to the groundwater was 7.5×103 m3/d, the annual recharge volume was 2.7375×106 m3. This result demonstrates that the water environment of the Baiyangdian Lake and the groundwater in the south part of the study area are significantly affected by anthropogenic activities, and therefore these regions should be protected and restored in the future. Baiyangdian Lake is the main recharge source of the groundwater, it has a significant effect on the volume and quality of the groundwater. The accurate description of the interaction between the Baiyangdian Lake and the groundwater can provide scientific support for the management of water resources in Xiongan New Area.
