承德市大气环境质量的模糊数学综合评价

Fuzzy Comprehensive Evaluation of Chengde City Atmospheric Environment Quality

文章通过运用模糊数学方法,选用二氧化硫、二氧化氮、可吸入颗粒物、灰尘、硫酸盐化速率作为评价因子,参照国家大气环境质量标准,计算大气污染因子权重、权重分配系数和隶属度等对承德市双桥区、双滦区、开发东区、大学园区空气质量进行评价。综合评判结果表明,双桥区、双滦区大气环境质量达到中污染水平,开发东区、大学园区大气环境质量为轻度污染,承德市整体达到中等污染程度,与一般评价方法相比更客观。

In this paper, the method of fuzzy mathematics, selection of sulfur dioxide, nitrogen dioxide, particulate matter, dust, sulfation rate as evaluation factors, with reference to the standards for the quality of atmospheric environment, through to calculate the weights of the pollution factor, weights and membership of Chengde City double bridge area, Shuangluan District, Development Zone, University Park air quality evaluation.Comprehensive evaluation results showed that the Shuangqiao District of atmospheric environmental quality reached the level of heavy pollution, Shuangluan District atmospheric environmental quality to achieve the pollution level, development zone, University Park, the atmospheric environment quality is the mild pollution, overall level to medium pollution.
