基于评价区水文地质条件,对中水水库修建后,可能对地下水环境产生影响的预测要点进行了分析。在确定会对地下水位及水质影响的基础上,分别采用浸没临界范围来预测水位的影响;采用评价标准浓度来反映对地下水质污染程度;根据设计预测情景模式,利用解析法及数值法对评价区地下水环境影响进行了评价。研究表明,在中水水库建设对地下水环境影响预测过程中,重点是确定浸没临界范围以及评价标准浓度来反映地下水环境影响程度,是该类地下水环境影响评价预测的要点。
Based on the hydrogeological conditions in the assessment area, the prediction points that may have an impact on the groundwater environment after the construction of the Zhongshui Reservoir are analyzed. On the basis of determining the impact on groundwater level and water quality, the submerged critical area is used to predict the impact of water level. The evaluation standard concentration is used to reflect the degree of groundwater pollution. According to the design prediction scenario, the analytical and numerical methods are used to evaluate District groundwater environmental impact was evaluated. The research shows that in the process of predicting the impact of the construction of the Zhongshui Reservoir on the groundwater environment, the key point is to determine the critical range of immersion and the evaluation standard concentration to reflect the impact of the groundwater environment, which is the key point of this type of groundwater environmental impact assessment.
