分析了肇庆市2013年七星岩风景区和市区的空气质量。监测结果表明，七星岩与市区的各类大气污染物呈现类似的月际变化规律，普遍呈夏季污染较轻但秋冬季污染较严重的态势。七星岩的臭氧浓度显著高于市区，PM10与 PM2.5浓度略高于市区，与市区相比，大多数月份七星岩具有较低的 SO2、NOx与 CO 浓度，表明七星岩的空气一次污染较轻，但二次污染严重。七星岩风景区空气质量差于市区，大量天然源 VOC 叠加少量人为排放的气态污染物生成较多二次污染物是导致自然风景区空气质量差于市区的重要原因。

The air quality of the downtown area of Zhaoqing and the Qixingyan scenic spot was compared.The re-sults showed that the monthly change of the air pollutants in both areas was similar.The air pollution in the summer was better than that in the winter in general.The concentration of ozone in Qixingyan was significantly higher than that in the downtown area.However,the concentrations of PM10 and PM2.5 in Qixingyan were a little higher than that in the downtown.The relatively low concentrations of SO2 ,NOx and CO were found in most of the months in Qixiangyan,which showed that the first pollution in Qixingyan was much less serious than the secondary pollution. The air quality in Qixingyan was worse than that in the downtown.The VOC from the natural sources plus the air pollutants from the human activities produced the secondary pollution that was the main drivers causing a worse air quality in Qixingyan.
