安徽省城市空气质量状况评价
|
摘要
对安徽省城市空气质量进行分析评价,并利用空气污染综合指数和Spearman秩相关系数法得出空气质量的优劣及变化趋势。结果表明,安徽省城市空气质量总体上属轻度污染且呈下降趋势,其中二氧化硫和总悬浮颗粒物浓度下阵趋势明显,氮氧化物浓度则有所上升,未来将成为安徽省城市空气质量的制约因子。
We analyze atmosphere quality of cities in AnHui province, and obtain condition of atmosphere quality and its variation trend with comprehensive index of atmosphere pollution and spearman order relative coefficient method, The result shows that atmosphere quality in sities of AnHui province is lightly polluted totally, and degree of pollution is in descending trend, The concentration of SO2 and TSP is obviously in descending trend, but that of NOx is ascending and it will be restrictive factor of atmosphere quality in cities of AnHui province.
