大同市城郊地下水超采区的发展演变
|
摘要
大同市作为北方资源型缺水城市,地下水开采量超过其国民经济总供水量的80%,累计超采地下水量超过21亿m~3,形成了城西、城南、城北三大水源地漏斗区,超采区总面积为461 km~2,其中严重超采区136 km~2。文中主要是对大同市城郊地下水开采历史、超采区形成、发展及演变进行分析评价,进而为超采区的治理、修复提供科学依据。
Datong is seriously short of water resources,and the amount of groundwater exploitation has exceeded 80% of the total water supply of datong's national economy. The accumulative over-exploitation of groundwater exceeds2.1 billion cubic meters,forming the funnel area of three water sources in the west,south and north of the city. The total area of the over-exploitation area is 461 square kilometers,including 136 square kilometers of the seriously over-exploitation area. This paper mainly analyzes and evaluates the history of groundwater exploitation and the formation,development and evolution of overexploited areas in the suburbs of Datong city,so as to provide scientific basis for the management and restoration of overexploited areas.
