污染源半定量化的地下水有机污染风险评价

结合细河沿岸地区水文地质条件及地下水有机污染特征,通过AHP法确定权重,建立DRSIC模型,将评价结果与污染源荷载评价叠加,构建研究区有机污染风险评价模型.并通过研究区有机污染特征检验模型的合理性.结果表明:区内大部分地区有机污染风险中等或低.只有细河沿岸、杨士至于洪区一带污染风险处于高水平.评价结果较好的符合研究区有机污染现状.

Risk evaluation of groundwater organic pollution by semi-quantified hazard

Based on the hydrogeological conditions and the organic pollution characteristics in this study area, DRSIC model has been established to classify the vulnerability of groundwater. According to this vulnerability results and hazard load conditions, organic pollution risk assessment model have been built and verified by the groundwater organic contamination situation. The weighting of all models was calculated by AHP (analytic hierarchy process). The assessment results indicated that the levels of organic pollution risk along Xihe River and Yangshi to Yuhong Area was higher than the other areas. The assessment results are well reflected organic pollution status in this study area.
