由抽水试验成果谈济南长孝水源地回灌补源

通过4.5万m3/d开采性抽水试验的观测表明长孝水源地具有较好的富水性及调蓄能力，开采潜力巨大。为保证长孝水源地的长期开采，应尽早采用外引内拦等工程措施，在孝里铺洼地地区实现地表水的回灌补源。这对提高城市供水保证率，恢复当地生态环境均具有十分深远的意义。

Study on Artificial Groundwater Recharge of Changxiao Water Source By Pumping Test in Jinan City

Through exploitation pumping test observation with the water amount of 45000 m3/d of No.1 Changxiao water source, it is showed that Changxiao water source has a good water enrichment and storage capacity and exploitation potentiality. In order to ensure long term extraction of Changxiao water source, some countermeasures should be adopted, such as outward water diversion and internal water stop. Thus, artificial groundwater recharge of surface water in Xiaolipu depression area can be realized. It will have a very significance in improving rate of water supply in city, and recoverying local ecological environment.
