岩溶水系统地下水资源保护区划研究—以聊城东阿岩溶水系为例

Research on Protection Division of Groundwater Resources in Karst Water System—Setting Dong'e Karst Water System in Liaocheng City as an Example

摘要:

针对地下水水质恶化的现象，以东阿岩溶水系统为研究区域，建立地下水资源保护区划模型，对水系统内浅层和岩溶地下水分别进行水资源保护区划，结果表明：浅层地下水无自然防护区，均需要人为防护与治理，重点防护区占总区域面积的1/2；岩溶地下水下马头水源地以及其影响区域为重要水源地防护区，一般防护区占总区域面积的60%，重点防护区占23.66%，刁山坡监测点以及其影响区域为浅层和岩溶地下水的修复治理区。

Abstract:

Aiming at the deterioration of groundwater quality, the model of groundwater resources protection zoning has been established by taking the karst water system of Dong’e as the research area. The water resources protection zoning of shallow water and karst groundwater in the water system have been analyzed. It is showed that:shallow groundwater has no natural protection area. They all need human protection and management. The key protection area accounts for 1/2 of the of total areas. The Karst ground water source area and its impact area are important natural protection areas. The general protection area accounts for 60% of the total areas, while the key protection area accounts for 23.66%. Diaoshanpo monitoring areas and its impact areas are shallow and karst groundwater remediation areas.
