安徽省阜阳地区深层地下水资源的开发利用

Exploitation and Utilization of the Deep Groundwater Resource in Fuyang Area,Anhui Province

阜阳地区深层水指蕴藏于４０ｍ以深第四第及上第三系的松散岩类孔隙水，下限深度一般３００～９００ｍ属承压水。水位埋深６～２０ｍ，集中开采区２０～４０ｍ。按５０ｍ水位降深估算，天然储量＊约３８．５×１０８ｍ３。深层水以水质优良、储量较大且难以更新为主要特点。其中６６００ｋｍ２范围内蕴藏有高碘地下水，有的已达到国家饮用天然矿泉水标准。６００ｍ以深水温可达３０℃以上，为有待勘查和开发的地热水资源。深层水是目前阜阳地区城镇集中供水的唯一水源。近年来，随着各地竞相抢采深层水的强度逐年加大，合理开发利用深层水资源、保护地质环境，已成为区内水资源开发利用中最突出的问题。开发深层水须以勘查和监测资料为依据，在区域性统一规划可利用总水资源的基础上，实行分质供水、优水优用。要开发高碘地下水和地热水资源，兼顾资源效益。

The deep groundwater means water derived from the unconsolidated Quaternary and tertiary porous formations deeper than 40 m The estimated depth in this paper is about 300 900 m at maximum It is the confined groundwater,characterized by good water quality,abundant water amount but the renewal is diffcult In recent years,exploitation of the deep groundwater has been increased rapidly and the rational exploitation and protection has become the key issue The regional deep groundwater resource is scientifically regulated based on the monitoring data and the total groundwater resource to coordinate the relations of resource benefit,economic interest and environmental nature
