摘　　要：目的对唐山南湖中央生态公园大气环境质量进行监测,分析首要污染物和超标污染物,评价园区大气质量状况。方法采用功能分区法进行采样点布置,共设7个采样点,位于上风侧的某公园作为对照点。测定大气中的二氧化硫(SO2)、二氧化氮(NO2)、臭氧(O3)、总悬浮颗粒物(TSP)、可吸入颗粒物(PM10)、细颗粒物(PM2.5)质量浓度,计算各指标的空气质量分指数和不同监测区域的空气质量指数,对园区大气环境质量进行评价。结果园区大气中PM2.5质量浓度高于国家Ⅱ级标准,其余指标均未超标;各监测区域中,植物园SO2、TSP、PM10、PM2.5质量浓度最高,其空气质量分指数也最高。园区空气质量指数为115.6,空气质量分级为三级。结论在本研究的监测时间内,PM2.5是园区的首要污染物和超标污染物,园区空气质量分级为三级,质量状况为轻度污染。Objectives To monitor and assess the atmospheric environment quality and analyze the primary pollutant and the pollutants beyond the national standard limits in South Lake Central Ecological Park in Tangshan city. Methods The sampling spots were arranged according to the construction status and the distribution of functional areas in the park,and seven monitoring areas were selected. The control point was in another park located at the windward side. The concentrations of SO2,NO2,O3,total suspended matter( TSP),PM10and PM2. 5in the ambient air were determined. The air quality of each selected area and the whole park area was assessed by calculating individual air quality index( IAQI) and air quality index( AQI). Results PM2. 5was the primary pollutant in the park and the concentration of PM2. 5in the whole park was higher than the national standard limits.Other pollutants were all lower than the standard limits. In seven monitoring points,the levels of SO2,O3,TSP,PM10,PM2. 5and IAQI in the botanical garden were the highest. The AQI in the park was 115. 6 and the air quality was grade Ⅲ. Conclusions PM2. 5was the primary pollutant and the only pollutant beyond the standard limits during the monitoring period. The air quality was grade Ⅲ,the status of air in the park was mild polluted.
