【摘要】：根据2013年11月1日至2015年10月31日中国环境监测总站对山东省17个地级市的空气质量指数(AQI)的逐日监测数据,结合各地级市的地理位置和不同季节的气候特点,从宏观角度对山东省空气污染的时空分布特征进行分析。结果表明:山东省空气质量状况存在明显的地域差异,东部沿海地区空气质量普遍较好,内陆城市污染相对严重,且沿海城市的AQI呈现由东南向西北逐渐增大的趋势;山东省AQI变化具有明显的季节特征,呈现冬季污染较重、夏季污染较轻的季节特点;虽然春季发生空气污染的频率比秋季高,但是秋季发生污染时的污染程度较春季严重;4个气象区中,空气质量最好的是半岛地区,其次是鲁南地区,鲁中和鲁西北地区的空气质量较差。
[Abstract]:According to the daily monitoring data of air quality index (AQI) of 17 prefecture-level cities in Shandong Province from November 1st 2013 to October 31st 2015, combined with the geographical location and climate characteristics of different seasons in each prefecture-level city, The spatial and temporal distribution characteristics of air pollution in Shandong Province are analyzed from a macro perspective. The results show that there are obvious regional differences in air quality in Shandong Province, the air quality in the eastern coastal areas is generally good, and the pollution in inland cities is relatively serious. The AQI of coastal cities increased gradually from southeast to northwest, the AQI variation of Shandong Province had obvious seasonal characteristics, showing the seasonal characteristics of heavy pollution in winter and light pollution in summer. Although the frequency of air pollution in spring is higher than that in autumn, the degree of pollution in autumn is more serious than that in spring. Among the four meteorological regions, the air quality is the best in the peninsula area, followed by the southern Shandong region. The air quality in central Shandong and northwest Shandong is poor.
