摘要
通过近10 a大气污染物的监测数据,分析了辽阳市采暖期与非采暖期大气环境中污染物的变化情况。结果表明:采暖期污染物超标及近年来超标趋势加快是由于燃煤增加、气象条件不利和机动车增加等原因所致,并据此提出了扩大集中供暖面积、推广新的供暖方式、加大机动车尾气治理等防治对策。
Based on the monitoring data in past decade,the changes of pollutant contents in atmospheric environment were analyzed during the heating period and non-heating period in Liaoyang. The results indicated that the pollutants contents exceeded the standard during the heating period because of the increase of coal combustion and disadvantageous meteorological conditions as well as the increase of motor vehicles. Thus, some prevention and cure countermeasures were presented such as recommending the central heating, using the new heating ways and controlling the exhaust gas of motor vehicles.
