【摘要】 应用数值模拟方法,对洛河水面工程修建后,洛阳市盆地区地下水资源量变化进行了评价,并对洛阳市区主要水源地的开采潜力进行了分析。研究结果表明,洛阳市2007-2009年,地下水年平均可开采量为3.68×108m3,洛河水面工程的修建加强了洛河水对地下水的补给,年增加补给量0.8×108m3左右,目前伊、洛河对洛阳市地下水的补给量达到2.78×108m3/a。水面工程修建后,洛南水源地每天增加开采量6×104m3,漏斗中心区水位增加降深2m左右;李楼水源地每天增加开采量6×104m3,漏斗中心区水位增加降深2.2m左右。更多还原

【Abstract】 The changes of groundwater resources in Luoyang basin after the construction of the Luohe river surface project were evaluated by using numerical simulation method, and the exploitation potential of the main water source area in Luoyang city was analyzed.The research results show that the average annual exploitable amount of groundwater in Luoyang city was 3.68 × 108 m3 from 2007 to 2009. The construction of the Luohe river surface project has strengthened the recharge of the water from the Luohe river to the groundwater, with an annual increase of about 0.8×108 m3. At present, the recharge amount of the groundwater in Luoyang city from the Yihe and Luohe rivers has reached 2.78 × 108 m3/a.After the construction of the water surface project, the water source area in Luonan will increase the exploitation amount by 6 × 104 m3 every day, and the water level in the center of the funnel will increase the drawdown by about 2 m; The exploitable amount of groundwater is increased by 6 × 104 m3 every day in Lilou water source area,and the water level in the central area of the funnel is increased by about 2.2 m.更多还原
