【摘要】：根據(jù)十堰市2013-2015年的空氣質(zhì)量數(shù)據(jù),對(duì)十堰市空氣質(zhì)量狀況及PM_(10)、PM_(2.5)、SO_2、NO_2的濃度變化特征進(jìn)行了分析。結(jié)果表明,十堰空氣質(zhì)量達(dá)標(biāo)率逐年上升,SO_2、NO_2、PM_(2.5)年均濃度呈逐年下降趨勢(shì),PM_(10)、PM_(2.5)有著顯著的相關(guān)性,各項(xiàng)污染物濃度春、冬季高于夏、秋季,且在12月至次年1月監(jiān)測(cè)結(jié)果最高、6-8月份監(jiān)測(cè)結(jié)果最低,4個(gè)因子不同季節(jié)的日變化規(guī)律基本一致,但各因子之間的變化規(guī)律又不盡相同。
[Abstract]:Based on the air quality data of Shiyan City from 2013 to 2015, the air quality status and the concentration variation characteristics of PM_ (10), PM_ (2.5) and SO_2,NO_2 in Shiyan City were analyzed. The results showed that the rate of reaching the standard of air quality in Shiyan increased year by year, the average annual concentration of SO_2,NO_2,PM_ (2.5) decreased year by year, and there was a significant correlation between PM_ (10) and PM_ (2.5). The concentration of pollutants in spring and winter was higher than that in summer and autumn, and the monitoring results were the highest from December to January of the following year, and the monitoring results were the lowest from June to August. The diurnal variation of the four factors is basically the same in different seasons, but the variation law among the four factors is not the same.
