为改变邯邢矿区岩溶水位持续下降、降落漏斗不断扩大的现状,实现泉水复涌,首先通过区域岩溶水资源的调查与供需平衡分析,得出泉水断流的主要原因是开采量大于补给量;其次,以岩溶地下水系统模型为基础,通过模拟预测表明：如果保持现有系统补给量与开采量不变,岩溶水水位仍将不断下降、达活泉及百泉断流、水生态环境持续恶化。为此,应用水资源区域配置的理念,建立了以百泉泉域水环境持续好转为目标的水资源管理模型,在邢台市区生活用水、农业用水基本保持不变,以及百泉泉域总开采量小于总补给量等约束条件下,解算得到了总用水量减少0.591 m~3/s、泉域总补给量减去总开采量盈余0.29 m~3/s的优化供水方案。通过模型模拟预测,按照此优化方案,泉域水位逐步恢复,10年后百泉和达活泉泉水重新复涌。
In order to change the karst water table continuous drop and the drop hopper continuously expanded status in Hanxing Mining Area and to realize the spring re-gushing,firstly with the investigation and the supply and demand balance analysis on the regional karst water resources,the main causes of the spring no-flow were the water mining value higher than the refilling volume. Secondary,based on the karst underground water system model as the basis,the simulation prediction showed that if the refilling volume of the available system retained and the mining volume unchanged,the karst water table would be continuously dropped,the Huo spring and the Bai Spring would be no water flow and the water ecologic environment would be continuously worst. Therefore,with the idea of the water resource regional allocation,a water resources management model was established to keep the water environment of Baiquan spring region continuously getting better as the target. The domestic water in Xingtai downtown and the agriculture water would be kept no change. As well as the total mining volume of the water in Baiquan Area was less than the total refilling volume and other restriction conditions,the calculation showed that the optimized water supply plan was obtained with the total water consumption volume reduced by 0.591 m~3/s and the total refilling volume of Baiquan Area with a surplus of 0.29 m~3/s and with the minus of the total mining volume. With the model simulation prediction,according to the optimized plan,the underground water table in the spring area would be steadily recovered and after 10 years,Baiquan and Dahuoquan spring water would be re-inflow.
