【摘要】：目的了解中山市2007—2016年环境空气质量的变化趋势及基本状况。方法收集中山市2007—2016年环境空气污染物二氧化硫(SO_2)、二氧化氮(NO_2)、一氧化碳(CO)、臭氧(O_3)、可吸入颗粒物(PM_(10))和细颗粒物(PM_(2.5))的年平均浓度或特定的百分位数浓度监测数据,采用Spearman秩相关系数法和环境空气质量指数法分析其变化特征及基本状况。结果中山市2007—2016年SO_2、NO_2和PM_(10)的年平均浓度总体呈下降趋势(r_s分别为-0.976,-0.809,-0.873,P0.05)。2013—2016年SO_2、NO_2、CO、O_3、PM_(10)和PM_(2.5)总达标率分别为100.0%,97.4%,100.0%,90.6%,98.0%和91.2%;近4年环境空气质量综合指数由高到低依次为2013年2014年2015年2016年。2013—2015年主要污染物为PM_(2.5),2016年主要污染物为NO_2。结论中山市近10年SO_2、NO_2和PM_(10)年均浓度总体呈下降趋势,PM_(2.5)和NO_2是近4年主要污染物。
[Abstract]:Objective to understand the change trend and basic situation of ambient air quality in Zhongshan City from 2007 to 2016. Methods to collect data on the annual average concentration or specific percentile concentration of sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone, particulate matter, PMSP, and fine particulate matter, respectively, in Zhongshan City, 2007-2016, so _ 2 / S _ 2C _ 2, CO _ (2), O _ (3) O _ (3), respirable particulate matter (PMSP) _ (10 ~ (10) and fine particulate matter (PPM) ~ (2.5). The Spearman rank correlation coefficient method and ambient air quality index method were used to analyze its variation characteristics and basic conditions. Results the annual average concentrations of total annual average concentrations in Zhongshan City for the period 2007-2016 were -0.976- 0.809- 0.809- 0.873P0.05.2013-2016) and PM2.5), respectively.) the total attainment rates of the annual average concentrations were -0.976- -0.809- + -0.873P0.05. and PM2.5), respectively.) the total attainment rates of the annual average concentrations were 100.00 / 97.40.090.698.0% and 91.2%, respectively; in the last four years, the composite index of ambient air quality in 2013 was from high to low to that of 2014. The main pollutant in 2016, 2013-2015, is PMSP 2.5, and the main pollutant in 2016 is No2. 2. Conclusion in recent 10 years, the average annual concentrations of SO2No2 and PMs10) in Zhongshan City showed a downward trend.) and NO_2 were the main pollutants in the last 4 years.
