摘要
统计了昆明市2013年全年每日PM2.5浓度和气象参数。分析表明昆明城区PM2.5的污染主要与气象条件和建筑施工扬尘两个重要因素有关,影响PM2.5的污染气象因素为气温、风速、雨量、湿度、气压等;大拆大建的施工扬尘,是昆明市PM2.5和空气污染的主要来源,其他则来源于工业排放、交通扬尘、汽车尾气排放。昆明市PM2.5的污染防治,应以建筑施工扬尘的污染防治为重点。
The daily meteorological data and PM2.5 concentration of the whole year of 2013 was used to analyze the factors causing PM2.5 pollution in Kunming. The results showed that PM2.5 pollution in Kunming city correlated closely with meteorological conditions and dusts from the construction sites. The meteorological conditions such as temperature, wind speed, rain, humidity, and air pressure impacted the dispersion of dusts. In the meantime, the dust emissions from the construction sites in Kunming city were the main sources of PM2.5. Industrial, transportation, and tail gas contributed a significant part of particle materials. The key should be put on controlling the dust from the construction sites in Kunming.
