井灌区水量的过度开采,导致地下水位大幅度下降,工农业用水提水成本大幅攀升,并形成降深漏斗区,进而引发地质灾害。引黄河水进行回灌补源,效果虽明显,但易受农时、黄河水情影响,且费用较高。利用雨季雨洪资源,适时进行回灌补源,可遏制地下水下降势头,改善井灌区用水条件和生态环境。 The over-exploitation of water in well irrigation areas led to a drastic drop in groundwater table, a drastic increase in the cost of water for industry and agriculture, and the formation of a deeper funnel zone, which in turn triggered geological disasters. Reuse the Yellow River water recharge recharge, the effect is obvious, but susceptible to farming, the Yellow River water conditions, and the higher costs. Use rainy season rainwater resources, timely recharge recharge sources, to curb groundwater momentum of decline, improve well irrigation water conditions and ecological environment.
