摘要
近年来我国经济高速发展,于此同时国家近年的规划也越来越提倡节能减排,从而使我国空气质量得以大幅度改善.但在东北地区的冬季,尤其是11月份到次年1月份的雾霾天气一直比较严重.根据2018年的全国城市空气质量排名,长春市空气质量排名第28位,AQI综合指数4.07,主要污染物来源于PM 2.5.针对长春地区的城市特殊性,选取净月开发区大学城周边主干道,实测2018年11月至2019年1月PM 2.5在大气中的浓度,所测数据与中国环境总站对长春地区分布点上传的监测数据进行了综合对比分析,由对比实验检测点逐时数据采样发现,测试样本中12月的PM 2.5浓度变化最为强烈,本文对长春地区与实验检测点的数据进行了对比分析,并在实验监测点各时段污染物浓度对比分析的基础上,总结了污染物产生的原因,并根据国家现行相关政策提出了建设性对策.
In recent years,the air quality in China has been greatly improved with the rapid development of economy and the promotion of energy saving and emission reduction.But haze weather in Northeast China has always happened.According to the 2018 city air quality ranking,Changchun is ranked 28th,the composite index is 4.07,the main pollutant is PM 2.5.In view of the city particularity of Changchun area,the main road around the university town of Jingyue development zone is selected to measure the concentration of PM 2.5 from November to January 2018 and the monitoring data of Changchun area by China Environmental General Station.Time-by-hour data sampling and detection of the point of detection in contrast experiment The change of PM 2.5 concentration in December was the strongest in the test sample.The data of Changchun area and the experimental detection point were compared and analyzed,and the pollutant concentration in each period of the experimental monitoring point was compared and analyzed.And according to the current relevant policies of the country put forward constructive countermeasures.
