摘　　要：目的克服传统化学危害监测重点区域判断存在的主观局限性和结果不确定性问题,提高化学危害监测重要区域选择的科学性。方法通过对化学危害监测重要性影响因素的统计分析,构建化学危害监测区域重要性排序的科学量化模型,并利用Spearman秩相关系数分析,比较主客观赋权法的指标权重,利用Kendall相关性分析对三种排序方法进行综合判断,提出一种结合了相似度组合排序法(K-WTV)和相似度组合赋权法(S-AEF)的方法对化学危害监测区域重要性进行排序。结果以某大型城市某地区作为化学危害监测区域,以其为应用实例,S-AEF结合K-WTV法计算所得结果与乘法合成法、最优赋权法、博弈论赋权的计算结果相似度分别为0.659、0.913、0.659,大于临界值,且基本符合现实经验的判断,证明本文方法的可行性。结论此方法结果具有客观性、可行性和适用性,并且更加科学合理,可为解决化学危害监测区域重要性排序等不确定性问题提供一种新思路。Objective To overcome the subjective limitations and uncertainty of results in the traditional judgment on key areas of chemical hazard monitoring and to improve the scientific selection of important areas of chemical hazard monitoring.Methods Based on the statistical analysis of the factors affecting the importance of chemical hazard monitoring,a scientific quantitative model was constructed to rank the importance of chemical hazard monitoring areas.The index weights of subjective and objective weighting methods were compared by Spearman rank correlation coefficient analysis,and three ranking methods were judged comprehensively by Kendall correlation analysis.In this paper,a spearman-based combined AHP,EWM,and FAHP assignment method(S-AEF)and a Kendall-based W,TOPSIS,and VIKOR integrated ranking method(K-WTV)were proposed to rank the importance of chemical hazard monitoring areas.Results As an example,taking a certain area of a large city as a chemical hazard monitoring area,the similarity between the results calculated by S-AEF combined with the K-WTV method and multiplicative synthesis method,the optimal weighting method,and the game theory weighting method was 0.659,0.913,and 0.659,respectively,which were larger than the critical value and basically consistent with the judgment of practical experience,which demonstrated the feasibility of this method.Conclusions The proposed method was objective,feasible,applicable,and scientifically reasonable.It can provide a new idea for solving uncertain problems,such as the ranking of the importance of chemical hazard monitoring areas.
