摘要
层次分析法是一种定性和定量相结合的、系统化、层次化的分析方法,是决策者按照人类决策过程的"分解—判断—综合"的思想特点,对复杂系统的决策思维过程模型化、数量化的过程。通过分析和研究,从水质和水量两方面入手,建立了矿山水环境质量评价指标体系,应用层次分析法将各层次权重综合,计算出各层次要素对总目标的组合权重,最终确定影响矿山水环境的主要因素为矿化度、pH值、矿山疏排水量以及有机污染指标。
Analytic Hierarchy Process method is a combination of qualitative and quantitative, systematic, hierarchical analysis method. The decision makers have the decision - making process of complicated systems modeling and quantitative, in accordance with the ＂decomposition - judge - integration＂ decision- making process of human thinking characteristic.Through analysis and research, commence on the two aspects of quality water and quantity, the quality evaluation index system of mine water environment was established. AHP method was applied to integrate all layers＇ weights together and calculate the combined weights of elements at various levels versus the overall objective. Ultimately the main factors that impact mine water environment were determined as salinity, PH value, draining displacement of mining and organic pollution indexes.
