摘要
汞矿区的污染问题越来越受到重视，对汞矿区进行环境风险评价显得尤为重要．风险评价方法和模型的研究是进行环境风险评价的重要内容．根据汞矿区的区域环境敏感目标以及污染事故类型，结合层次分析法的原理，建立层次分析模型，通过两两比较构造判断矩阵，利用和积法进行计算，得到层次排序并进行一致性检验，从而得到各污染事故类型的相对重要性，为下一步的污染风险管理提供可靠依据．
The pollution problems of mercury mine are getting more and more attention, and to carry out environmental risk assessment for mercury mine is particularly important. Researching the methods and models of the risk assessment is an important content for the environmental risk assessment. According to the sensitive target of regional environment and the pollution incident type of the mercury mine, combined with the principle of Analytic Hierarchy Process, the hierarchy structure model was built. Then, the comparing judge matrix was structured. Used the sum and product method to calculate, got the hierarchical sorting and detected it with the consistency test, then the relative importance of pollution accident types was obtained. The result provided a scientific basis for risk management.
