摘要
根据关中盆地水文地质条件及地下水分布特点,概化出区域地下水流数学模型和水文地质概念模型,在此基础上利用Visual Modflow建立了关中盆地区域地下水数值模拟模型,并利用地下水位长观孔对模型参数进行了识别,使模型具有较好的模拟仿真度。利用识别后的模型研究了引汉济渭后傍河水源地开采对渭河径流量及区域地下水位的影响,结果表明,傍河水源地开采激发渭河补给量占总开采量的73.3%,引汉济渭后通过减少傍河水源地开采量可增加渭河干流水量,并使得渭河沿线城市地下水位有不同程度的回升。
According to the hydrological and geological conditions and the distribution characteristics of groundwater of the Guanzhong Basin, this paper built mathematical model of groundwater flow and the hydrological and geological concept model of the region. Based on this, this paper used Visual Modflow software to establish the numerical simulation model of the groundwater of the Guanzhong Basin and used long-term observation holes to recognize the parameters of the model to make the model have a good simulation effect. The recognized model was used to study the influence of groundwater exploitation of riverside water source area after diverting water from Hanjiang River to Weihe River to the runoff of Weihe River and the regional groundwater level. The results indicate that the recharge of the Weihe River incited by the groundwater exploitation from riverside water source area comprises 73.3% of the total exploitation amount. The implementation of the water diversion project from Hanjiang River to Weihe Riv- er can increase the mainstream water amount of the Weihe River by decreasing the exploitation from the riverside water source area, and make the groundwater level of the riverside cities rebounded to various degrees.
