朝阳市区内不同空气自动站点间数据差异性分析

2017年朝阳市区内4个空气自动站点位的优良天数差异明显,整体上呈现"两高两低"特点,即河畔小区、农业园区数值相对较低,西梁、八里堡数值相对偏高。通过分析2017年取暖期、非取暖期间各点位监测到的污染物数据特点,结合地域气候条件、气象参数等因素,分析产生这种差异性的原因,并提出相应污染防治措施。

The difference of excellent days among the four air automatic sites in Chaoyang city during 2017 is obvi- ous, showing the characteristics of ＂two high and two low＂ in general. The Hepan Community and Agricultural Park are relatively lower. Xiliang and Balipu Community are relatively higher. Based on the analysis the charac- teristics of pollutants data which monitored during heating period and non-heating period in 2017, combined with regional climatic conditions and meteorological factors, this paper analyzes the causes of this difference and puts forward the corresponding pollution prevention and control measures.
