【摘要】：目的了解中山市2007—2016年環(huán)境空氣質(zhì)量的變化趨勢及基本狀況。方法收集中山市2007—2016年環(huán)境空氣污染物二氧化硫(SO_2)、二氧化氮(NO_2)、一氧化碳(CO)、臭氧(O_3)、可吸入顆粒物(PM_(10))和細(xì)顆粒物(PM_(2.5))的年平均濃度或特定的百分位數(shù)濃度監(jiān)測數(shù)據(jù),采用Spearman秩相關(guān)系數(shù)法和環(huán)境空氣質(zhì)量指數(shù)法分析其變化特征及基本狀況。結(jié)果中山市2007—2016年SO_2、NO_2和PM_(10)的年平均濃度總體呈下降趨勢(r_s分別為-0.976,-0.809,-0.873,P0.05)。2013—2016年SO_2、NO_2、CO、O_3、PM_(10)和PM_(2.5)總達(dá)標(biāo)率分別為100.0%,97.4%,100.0%,90.6%,98.0%和91.2%;近4年環(huán)境空氣質(zhì)量綜合指數(shù)由高到低依次為2013年2014年2015年2016年。2013—2015年主要污染物為PM_(2.5),2016年主要污染物為NO_2。結(jié)論中山市近10年SO_2、NO_2和PM_(10)年均濃度總體呈下降趨勢,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.
