黎平县大气环境质量综合评价

Comprehensive evaluation of atmospheric environment quality in Liping County

为了评价黎平县大气环境质量状况,查明污染大气环境的影响因子,在参照国家大气环境质量标准的基础上,选取SO2、NO2、PM10作为评价因子,运用模糊数学方法对黎平县大气环境质量进行定量评价。结果表明:2010—2018年,黎平县大气环境主要污染因子为PM10,其中2014年主要污染物是SO2;2011—2014年为轻度污染,2015—2018年为清洁且空气质量指数呈现波浪型递增趋势;研究时段大气环境质量整体状况趋向好转。

In order to evaluate the atmospheric environment quality and to find out the factors influencing the atmospheric environment in Liping County,we selected SO2,NO2 and PM10 as the evaluation factors according to relative national standards,and carried out quantitative evaluation of the atmospheric environment quality of Liping County by using fuzzy mathematics method.The results showed that the main pollution factor of the atmospheric environment was PM10 from 2010 to 2018,while the main pollutant was SO2 in 2014.The atmospheric environment quality level was light pollution from 2011 to 2014;the atmospheric environment quality level was clean and the air quality index was increasing in a wavy trend from 2015 to 2018.The overall situation of the atmospheric environment improved from 2010 to 2018.
