地下水库运行效果评价体系构建与应用研究

Construction and Application of Evaluation System for Operation Effect of Underground Reservoir

滨海地下水库是重要的地下水源地,建立科学的地下水库运行效果评价体系对于地下水资源的开发利用与保护具有重要的科学意义和应用价值。本文考虑了地下水库的水资源、水环境属性和经济社会效益,选取水量、水质、脆弱性、经济社会效益为评价指标,建立了一套新的地下水库运行效果评价指标体系。基于改进的模糊综合法,构建了适于地下水库运行效果评价的模型,且以大沽河地下水库为例综合评价了该地下水库的运行效果。结果表明,大沽河地下水库运行效果评价结果为Ⅲ类,整体运行效果临界安全。但是地下水库的脆弱性综合指数较高,抗污染能力较差,地下水容易被污染。

Coastal underground reservoir is an important source of underground water.The establishment of a scientific evaluation system for the operation effect of underground reservoir has important scientific significance and application value for the development,utilization and protection of underground water resources.In this paper,the water resources,water environment attributes and economic and social benefits of underground reservoirs are considered,and the water quantity,water quality,vulnerability and economic and social benefits are selected as evaluation indexes to establish a new evaluation index system for the operation effect of underground reservoirs.Based on the improved fuzzy synthesis method,a model suitable for operation effect evaluation of underground reservoir is constructed.Taking the Dagu river underground reservoir as an example,the operation effect of the underground reservoir is comprehensively evaluated.The results showed that the effect of Dagu river underground reservoir operation evaluation results forⅢclasses,the overall effect of the critical safety.However,the comprehensive index of vulnerability of underground reservoirs is high,the anti-pollution ability is poor,and the groundwater is easy to be polluted.
