安徽省重要城市地下水应急供水水源地现状研究

近年来安徽省采取实地调查、资料研编、水量的估算和推算等方法,进行了全省17个重要城市地下水应急供水水源地的调查评价研究工作。在深入分析全省水文地质条件、了解地下水资源的分布规律和开发利用现状、摸清重要城市地下水的赋存条件和富水地带及水源地开采潜力的基础上,提出了地下水应急供水水源地的选择原则、开发利用程序及保护措施;初步选择出远景地下水应急水源地37个,评价总应急供水量116.7~145.2×104m3/d,可供2 224~2 884万人基本生活使用和5 685~7 060万人维持生活使用,为全省各重要城市应急供水机制建设提供可靠的地下水资源保障。

THE PRESENT SITUATION ABOUT GROUND WATER USED AS WATER SOURCE FOR EMERGENCY SUPPLY IN IMPORTANT CITIES IN ANHUI PROVINCE

In recent years,taking site investigation and information review,estimating and water quantity calculation,assessment on ground water used as water source for emergency supply was made in 17 important cities in Anhui province.Based on analysis of hydrological geology condition,the groundwater resource distribution and utilization status,the paper put forward： selection principle of the groundwater source to be used as emergency water supply,utilization procedure,and protection measures.Chosing 37 ground water emergency as water supply source with 116.7-145.2 million m^3/d.It can be supplied for 2 224-2 884 people to maintain their basic daily life and 5 685-7 060 million to survive.It is important for the emergency water supply mechanism of urban construction to provide reliable guarantee of groundwater resources.
