地下水如不进行统一管理,任意打井,过量开采,容易引起地下水位急剧下降、地面下沉、水质变坏和水源污染等恶果。维持地下水的平衡,需要借助于某些工程措施,在非用水季节将河道、池沼、沟渠里的水引入地下,贮存起来,这样可以补充地下水源的不足,保证地下水永续利用。 Groundwater without any unified management, arbitrary drilling, over-exploitation, easily lead to a drastic decline in groundwater levels, ground subsidence, deterioration of water quality and water pollution and other consequences. To maintain the balance of groundwater, we need some engineering measures to introduce the water in the rivers, ponds and ditches into the ground during non-use season to store the groundwater, which can supplement the shortage of groundwater sources and ensure the sustainable use of groundwater.
