从上海市水务部门了解到,自实施严格的地下水管理制度以来,该市地下水开发利用已由常规供水转为战略储备水源。目前,上海地下水开采量已大幅减少,回灌量已连续两年大于开采量。据介绍,上海已建立严格的地下水管理制度,凡地表水可到达的地方,原则上逐步停止地下水的使用,由此大幅压缩了地下水的开采量。2003年,上海市的地下水开采量为1亿吨,2012年减 The water department of Shanghai learned that since the implementation of a strict groundwater management system, the city’s underground water has been diverted from conventional water supply to strategic water storage. At present, the amount of groundwater exploitation in Shanghai has been substantially reduced, and the amount of recharge has been greater than that of mining for two consecutive years. According to reports, Shanghai has established a strict groundwater management system. Where surface water is reachable, the groundwater use will be phased out in principle, thereby drastically reducing groundwater extraction. In 2003, groundwater exploitation in Shanghai was 100 million tons, down from 2012
