摘要:

为从源头对饮用水源地实施有效保护,对河流型饮用水源地选址合理性进行科学评估,从法律制约、环境质量、水资源保障和环境风险角度,选择28个关键影响因子构建水源地选址评价体系.基于层析分析法建立评价体系数学模型,采用文献分析和专家问卷调查相结合的方法确定各级影响因子的权重,并将单准则下的权重进行合成.依据法律法规、技术标准和统计数据对影响因子进行分级和分值量化.通过因子的分值和权重进行加权计算,可给出选址评估建议.

Abstract:

To effectively protect drinking water resources,a scientific assessment on site selection of River drinking water resources was carried out.Twenty-eight key factors including law,environmental quality,water resources assurance and environmental risk were selected,and based on analytic hierarchy process(AHP),a mathematical model of assessment system was established.The weight of factors was defined by the method of document data and expert questionnaire,and these weights were synthesized under single criterion.These influence factors were classified and quantized with laws,technical standards and statistical data.According to the calculation of factor scores and weights,the recommendations of site selection can be given.
