摘　　要：目的研究深圳市2006—2016年大气污染物浓度变化趋势。方法收集深圳市7个国控环境监测点2006—2016年空气中SO_2、NO_2、PM_(10)的逐日日均浓度,其检测采用大气质量连续自动监测系统行监测,系统以光谱法仪器(差分吸收光谱仪)为主。结果深圳市2006—2016年空气中SO_2、NO_2、PM_(10)的年均浓度总体呈下降趋势,SO_2从0.0314 mg/m^3下降至0.0087 mg/m^3,NO_2从0.0520 mg/m^3下降至0.0376 mg/m^3,PM_(10)从0.0672 mg/m^3下降至0.0433 mg/m^3;每年日均浓度符合《环境空气质量标准》(GB 3095-2012)的天数和空气质量亦逐年上升。季节趋势看,每年冬、秋季各污染物平均浓度较高,夏季最低。结论深圳市2006—2016年SO_2、NO_2和PM_(10)浓度总体呈下降趋势,空气质量逐年明显改善,但相对发达国家空气质量标准,仍有较大提升空间。Objectives To study the trend of concentration of air pollutants in Shenzhen from 2006 to 2016. Methods Daily concentrations of SO2, NO2 and PM10 in the air were collected from seven national controlled sites in Shenzhen from 2006 to 2016. The determination was carried out by a continuous automatic system for monitoring atmospheric quality, mainly analyzed by spectroscopy （DOAS）. Results The annual average daily concentrations of SO2, NO2 and PM10 in Shenzhen from 2006 to 2016 were in a decreasing trend, the concentration of SO2 decreased from 0.0314 mg/m3 to 0.0087 mg/m3, NO2 decreased from 0.0520 mg/m3 to 0.0376 mg/m3 and PM10 decreased from 0.0672 mg/m3 to 0.0433 mg/m3, respectwely. The quality of daily average concentration of ambient air, assessed by the GB 3095-2012 Ambiant air quality standards, was also increasing year by year. For seasonal trends, the average concentration of pollutants in summer was the lowest, which was higher in winter and autumn. Conclusions The concentration of SO2, NO2 and PM10 in Shenzhen from 2006 to 2016 showed a downward trend, and the air quality had been improved year by year; comparing with the developed countries, efforts to control air pollution should be intensified.
