摘要
根据肥城盆地的自然条件和社会经济情况,以地下水的开采价值和原位价值为基础,建立肥城盆地岩溶地下水价值评价指标体系和分级标准,利用GIS技术进行指标空间分区和叠加分析,并采用模糊数学方法对肥城盆地地下水价值进行评价。结果表明:研究区地下水价值较高和高的区域主要分布在东南部奥陶系石灰岩地区和西北部寒武系石灰岩地区,这些区域也是研究区岩溶水的直接补给区,应加大对这些区域的保护。
According to the natural condition and social economic situation of Feicheng basin,this paper built the karst groundwater value evalua-tion index system and grading standards with groundwater ＂mining value＂ and ＂in situ value＂ as the foundation,through GIS-based spatial zoning and overlay analysis,and used the fuzzy mathematics method to evaluate the value of Feicheng basin groundwater. Results show that the area of higher and high groundwater value are mainly distributed in the Ordovician limestone areas in northwest and southeast Cambrian limestone areas and these areas are the direct recharge areas of karst water of the study area and the protection should be strengthened.
