摘要
选取攀枝花市西区2006-2016年度环境空气质量数据,运用Spearman秩相关系数分析环境空气质量变化,综合比较了西区在全国和四川省各城市的环境空气质量排名,分类比较了与西区排名相近的四个工业城市各指标每月及年均浓度值,得出西区近11年环境空气质量变化趋势及污染特征。研究结果表明,攀枝花市西区环境空气质量改善明显,但二氧化硫和一氧化碳仍处在较高浓度水平,臭氧已经成为影响空气质量达标率的主要污染物。
With the 2006-2016 economic and environmental data in western district of Panzhihua,this paper analyzed synthetically the changes of economic growth and environmental quality by Spearman rank correlation coefficient test, the rankings in environment quality of China and Sichuan province. Their monthly averaged values and annual average in western district of Panzhihua which the rankings was close to the other 4 industrial cities were classified and compared, which concluded that the air environmental situation and its development trend？and air pollution features of western district of Panzhihua. The results showed that ambient air quality was improved effectively; however sulfur dioxide and carbon monoxide were still higher level, ozone were the major pollutants which affected the atmospheric environment quality.
