发布时间：2019-07-12 12:38
【摘要】：根据十堰市2013-2015年的空气质量数据,对十堰市空气质量状况及PM_(10)、PM_(2.5)、SO_2、NO_2的浓度变化特征进行了分析。结果表明,十堰空气质量达标率逐年上升,SO_2、NO_2、PM_(2.5)年均浓度呈逐年下降趋势,PM_(10)、PM_(2.5)有着显著的相关性,各项污染物浓度春、冬季高于夏、秋季,且在12月至次年1月监测结果最高、6-8月份监测结果最低,4个因子不同季节的日变化规律基本一致,但各因子之间的变化规律又不尽相同。
[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.
